Why I Can’t Recommend PfSense To Fix Bufferbloat For Gamers

[@Jax7787]

Pfsense now has a patch available via the netgate forums that finally FINALLY resolves the issues it has had with its UPNP implementation. The underlying issues were that MiniUpnp's implementation on BSD needed needed the ability to add the correct outbound NAT rules corresponding to the ports it used for inbound port forwards, as well as nat anchors to be implemented on the miniupnp nat rules so they are followed before other outbound nat rules. The patch was created too late to be included in the last release, but it will be in he next release, and can be manually installed. I have yet to test it, but it looks like this problem has actually been solved. *Edit. The UPNP Fix has been added to PfSense CE 2.7.0. Pfsense will finally work for gamers with multiple systems, just enable UPNP set and forget!

[@partlyawesome]

What was this patch? did it work? Please let me know!

[@oriwan3786]

Well I’m a gamer by heart and an IT network engineer by profession. I’m using pfsense since years. Yes pfsense is complex but it is pretty straight forward. I never had any problems to setup the configuration needed for a game. Running on a dedicated server with a 4x Intel NIC with LAGG interface to a managed switch. I never had any bottlenecks on my WAN link (1gb FTTH) . The problem is you need to have deep network knowledge and understanding to setup. Still if you want to have a free firewall pfsense is the best currently.

[@VonCarlsson]

The problem, if you will, is getting over that initial knowledge hurdle, and it's a rather steep hurdle. One that most people are simply not willing to put in the required effort in order to overcome. Not because they're stupid or lazy, but rather because it's very technical and unless that interests you in the first place it's going to be major pain in the ass. As such, I think the video's conclusion is correct: it's not recommended for the average user; not even if the population in question consist primarily out of gamers.

[@steveburgess23]

Agree with this 100% though I’m running pfsense 4.4 with just upnp enabled without a static Nat rule and have a network status of reported as “moderate” buy the consoles and have zero issues with latency spikes. Forwarding the ports manually to get an “open” status has no noticeable effect on latency. If the router has plenty of memory there shouldn’t be an issue with these types of latency spikes anyway.

[@hothardwarehive1526]

@@VonCarlsson Well for the average users, bufferbloat shouldn't be an issue either as it is almost imperceptible until you are having a lot going on your network (traffics, many users) and you have some high bandwidth to reach the Internet.

[@haydenw8691]

Sophos Home UTM is also free for home use. Only limitation is the 50 IP address limit. It is also even more locked down than pfsense in the initial configuration and the installer takes a bit of work to succeed with a USB stick.

[@hothardwarehive1526]

@@haydenw8691 I would strongly suggest to use Sophos XG Home Free Edition instead as the interface is much better and is a Next Generation firewall that can do anything (IDS, IPS, Anti-virus and more). The only drawback that kept me switching from pfSense to Sophos was their abyssmal IPSec speed. Both of their own hardware (low-end to mid-end at least) or the software version (Pro or home edition) don't use the AES capabilities of modern processor(Intel and AMD) for encryption and everything falls back on the main cpu(s) (the advertised speed by Sophos for VPN speed are not achievable even at the lowest security settings). In pfSense you just enable the use of the encryption capabilities (AES offload) and you're back at your full ISP speed.

[@kanarie]

If you want to shape 500+Mbit (I've tested up to 750Mbit), get a router based on fast ARM chips and OpenWRT compatibility. E.g. Linksys WRT1900ACS or Linksys WRT32X. Flash to OpenWRT, set up SQM and use the "cake" traffic shaper to get perfect fairness of bandwidth as well as bufferbloat mitigation.

[@Monsieur2068]

For anyone seeing this now there is testing currently on a version of miniupnp to fix this, looks to be tested in pfsense 2.5.

[@JasonVanPatten]

I'm not terribly surprised by the troubles you ran into. pfSense is FreeBSD using the "pf" packet filter. I like pf a *LOT* from a firewall/protection/security perspective. It's highly flexible and configurable. But it defaults to "NO!!!!" Nothing about creating pf rules is simple and easy; while pfSense has made it a lot easier, it's still very much a manual process which will lean *more* towards security and *less* towards convenience.

[@RobinCawthorne]

It's easier to predefine the rules in a script or create it a config via the GUI and use it for a baseline in the future. pf and iptables are both unbelievably versatile!

[@JasonVanPatten]

Oh, I know. I've been using both for ... ever ... it seems. But the challenge Chris is/was trying to solve isn't really *easy* to do with pf. It *IS* doable, but not very simply. Again: it's aimed at security-over-convenience. much to the chagrin of some.

[@ddallmann1373]

pf is much easier to understand when compared to ip tables, if you don't have a tool to manage ip tables.

[@hothardwarehive1526]

The problem is using UPnP which no one should really use if they care about network security. pfsense since 2.4.4 has addressed this issue and you can set it up properly (see my reply above).

[@CMDRSweeper]

Same here actually, I am operating PFSense on my network, granted since it is just me I haven't seen these issues appear myself. However, I am not a strict gamer, I run my own VPN to gain access to my network, I have VLAN setups to split networks, and I have servers running that needs outside access from time to time. Stuff I have learned to set up correctly, but yes, PFSense defaults to no rather than yes, so you often have to figure out what it is denying and then figure out how to say yes in the most secure way.

[@mmmcrispyful]

I have been using pfSense for over 5 years now. I'm using it right now. We have two PS4's and two gaming PCs. I have never encountered an issue with getting the systems to play on the same game simultaneously. We play Fortnite Battle Royale with all systems since it supports cross-platform play, and we play a lot of The Division 2 on PC. No issues playing together. The simplest fix for the "Strict" issue that all games report with pfSense is to enable Hybrid Outbound NAT and add the Host PCs or consoles (eg. 10.0.1.15/32). No need to port forward or create any inbound rules. Outbound rules for each host and UPnP is all you need for the strict issue. The only issue with these settings that I have experienced is voice chat in The Division 2 does not work when set to Hybrid Outbound NAT, setting it to Automatic Outbound NAT fixes the issue. If you're having issues with multiple hosts and if you haven't already tried it, I recommend enabling NAT reflection mode's Pure NAT (System -> Advanced Firewall & NAT). As for reducing or eliminating buffer bloat using pfSense, well, that is a ripe PITA. I have tried multiple times before version 2.4.4 to get this working effectively, I have given up many times. Since it's been made a lot easier with 2.4.4, I will test it out and see how it works.

[@Felix-ve9hs]

I first used OPNsense (pfSense Fork) to use FQ_CoDel but needed weeks to research and tweak it, but with the Ubiquiti EdgeRouterX i needed 5 minutes to set up the Smart Queue. It works just as fine as my OPNsense Router, but has way fewer features and you can't use Custom Hardware

Great vid as always Chris. I think an up-to-date video-explanation from you in regards to "all things network" or something like "setting up your PC network for gaming" would be hugely popular.

[@jeffm2787]

If you use an OpenWRT system to pass traffic to the PFSense box via a transparent bridge using Cake the results are great. At that point however you might as well just run OpenWRT (LEDE). I just gave up with my SG-3100 in Favor of a Ubiquiti USG as I found the response is much much better. I may build another transparent bridge and use Cake, always trying to balance that 24/7 power usage with what I want.

As a newbie to all this, you've at the very least saved me from messing with PfSense. My brother moved in with me, I have two gaming PC's and multiple other devices and I need them all to work with a relative minimum of hassle. Looking forward to the video about whatever thing it is that's working better for you!

[@kirk1240]

I use pfsense with FQ_CODEL on an Intel NUC8I7HNK. Even with 1gbit the processor sits on single digit load %. You need to set up the queue and port forwarding (use hybrid NAT), but once its done, it works.

[@DavidGoettler]

I agree. I spent weeks troubleshooting only to realize this cannot be done. I caved and bought a USG to use a smart queue.

[@shimme01]

I am absolutely excited for the next video on bufferbloat control. My last two routers (Netgear R7800 and ER-X) have been inspired by your content and I use them in tandem for my current setup with the netgear acting as an AP. I lose about 30Mbps (180 to 150) off my package with QoS enabled, but its good enough for now. I tried OpenWrt on my R7800, but it was not using all the cores for QoS so I think I got around 100Mbps from it.

[@yukiseekyo]

PFSense is one of those Firewall Distro that go by security first and not supposed to be a one click solution to do everything but one you get it work then its a match made in heaven, untangle is the best one for gaming since it uses linux and apparently the BSD networking stack is a lot more strict on what it allows, comparing to linux that is more lax and most consumer routers uses the linux kernel as the back bone of the os.

Plus it supports geoblocking which is good i guess

[@permissionBRICK]

I finally managed to fix this. Apparently there is now a patch for the problem of UPNP not being able to switch ports, if the port is already in use, which claims you shouldnt need static port mapping anymore, which will be rolled out in the release after 2.4.0, but is available as a manual patch now. Also I had a separate issue, where upnp would just refuse to open my nat on pfsense, even though it seemed to be working, and it turned out I had not one but two other separate routers in my network which were running in wifi client mode, however were still running upnp server, since apparently you need to disable this separately, and the games tried to forward ports on these routers instead of my pfsense.

[@devidby0]

Had this issue with R6 Siege. I have 3 OpenVPN clients on my PFSense so I route each computer over a separate OpenVPN which allows me to have up to 4 devices playing together online. If you forget to enable you have to exit the game and reset states. Not a set and forget by any means but it does work. So far is the only issue I have had with PFsense over the years of using it.

[@solidus1983]

This is why i use OpenWRT with Cake SQM, however you could check the kernel log to see if nf_conntracks is working which is part of UPnP, if it doesn't it will show an error like "nf_conntrack: default automatic helper assignment has been turned off for security reasons and CT-based firewall rule not found. Use the iptables CT target to attach helpers instead."

[@swmike]

I run OpenWRT on WRT1200AC which provides enough throughput to do ~500 megabit/s using CAKE / FQ_CODEL (I personally use this on a 250/100 megabit/s connection and I am not even close to running the CPU full). If you install OpenWRT on the same PC hardware that you installed pfSense on you should be able to easily get full gig forwarding speed, with same UPNP etc support, and enable SQM to fix bufferbloat. You install basic OpenWRT and then you add the sqm_scripts package and the equivalent luci package, and then you can configure this from LUCI, quite easily. openwrt.org/docs/guide-user/network/traffic-shaping/sqm

[@Zeratuhl]

Don't create manual rules for a specific game. Flip the NAT rule mode to manual and change the default outbound LAN-wide rules for the complete *-* (-500) port range to not use randomization with the "static port" checkbox. Works in Warframe and will enable multiple clients to play simultaneously.

[@ectotrix7399]

Hello, i'm gonna test that but i don't understand how is it different from what he did. I think he did 1 rule for each host with the "static port" checkbox.

[@Djhg2000]

So what would the advantage be with UPnP as opposed to NAT hole punching? The latter allows for direct UDP packets between clients and doesn't require the horrible mess of UPnP, in addition to requiring zero manual configuration. Apparently some games already use this.

[@nimeq]

The distinction is upnp doesn't require an outside server to open the connection ports. UPNP is fully reliable in the sense it will forward the port to the client, NAT hole punching is dependent on the router to accept the connection establishment between unknown remotes. Also neither of these provide any authenticity to the connection, they're just methods to make a connection over two clients that aren't directly connected to the internet.

@@nimeq > The distinction is upnp doesn't require an outside server to open the connection ports. UPNP is fully reliable in the sense it will forward the port to the client, NAT hole punching is dependent on the router to accept the connection establishment between unknown remotes. But they both require an external node for coordination of connections. NAT hole punching doesn't add much to the process of establishing connections and pretty much all but the extremely paranoid routers allow creating UDP connections. In one of the NAT hole punching strategies you essentially assert that there is a UDP "server" at the endpoint and send packets until the router figures out that the packages it's getting on the outgoing port are related. It can be blocked in theory but distinguishing between NAT hole punching and bulk data on a side channel is in practice, without deep packet inspection, literally impossible half of the time because you look like a UDP "client" initiating a connection. The only way you'd detect is to store a table of dropped invalid packets and cross reference them with every subsequent packet, resulting in first of all a massive table and then something like O(n) overhead for each packet. > Also neither of these provide any authenticity to the connection, they're just methods to make a connection over two clients that aren't directly connected to the internet. I'm a little confused by this statement. Authenticity is well outside the scope of both implementations, so I don't see why you're bringing that up?

[@nimeq]

@@Djhg2000 You're right, I have no idea what was thinking, I guess I've been working too long on STUN (Which has a different purpose). UPNP allows you to run a classic server, as opposed to having to use p2p connection establishment strategies. Not that it's really that important for your triple-A games these days, since you can't run your own server anyway. Not that you can't also just edit the firewall rules for it.

[@jamescater66]

Thanks for sharing the dslreports site with the buffer bloat test. I can improve my buffer bloat rating from C to A by enabling QoS on my Netgear router and reducing the download speed by 45% (350 => 200 Mbps). This reduces peak throughput of course, however fixing the ping spikes in game is priceless so worth the hit IMO

[@araemo]

Why in the world do games require a specific source port? I understand the server needs one because the clients need to know what to connect to (though, server browsers/matchmaking systems could list/provide the port as well..). But it needs to track per-client state anyway, there's no good reason to require the clients to use a specific source port. Just grab a random ephemeral (49152-65535 on windows) port and go from there... Is there ANY good reason for a game that doesn't run a listen server requiring a specific port on the clients?

[@squid11160]

Fairly sure it's not a source port, but rather a listen port on the client. Some games offload server capabilities to one of the clients if a client has a port open (GTA Online, for example), and for that it makes sense. However if that's not the case, I'd say it's poor design. One might argue that offloading server capabilities to clients is also poor design because it allows for easier cheating.

I use Traffic Shaper on pfSense and Bufferbloat is very good with it on a Multi WAN 450 MBit/s connection. Of course it runs on a i7 CPU. pfSense is doing nothing by it's own and that's good and what you want! You have to allow everything you want and setup correct. I don't know what you did there wrong, but I never used UPnP or NAT-PMP. It's also not recommenced. You should not forward any port for a game. I have multiple clients running the same game on the network and everything runs fine.

[@fusedOG]

The games will run fine but certain functions will not work depending on the game. If you have a strict NAT in Black Ops 4, you cannot invite players on the Internet to your party for example. However, you can still play the game just fine and even be invited by other players their party. My experience with pfsense is identical to what Chris ran into in this video. I.e, requiring static port outbound NAT to get past Strict NAT in games, as well as multiple players on the LAN having issues playing once this option is enabled. Also, I didn't use UPnP at all due to security concerns. I wish more games did UDP hole punching like Overwatch does. That game is flawless.

@@fusedOG I've never seen strict NAT or something similar. Can you tell me a game beside BO4 to test with? I only use static port for VoIP.

[@ianjameslake]

A simple solution for windows machines is to run NetLimiter. It can limit programs upload and download speeds (or the whole connection). This allows you to play games, while doing a download/upload. You just set the upload/download speed to 80-90% (or so) of it's maximum speeds. You can also get routers that can set limits per machine. Search for bandwidth throttling.

[@BattleNonSense]

While you can be somewhat successful with bandwidth throttling (I'm using Netlimiter a lot as you can see in my Netcode analysis videos), it quickly starts to show its limits as soon as you have 3+ users on your network using the internet at the same time.

[@ianjameslake]

@@BattleNonSense Yeah, the only way to make that work is for everyone to run netlimiter, or run a router that limits them. Which as you indicate doesn't work great with a 3+ people, as limiting them to 1/3rd the bandwidth each, doesn't suit most households.

[@jasongaunt]

Jesus @ Battle(non)sense this video (and yourself) came out of the blue from a KZbin recommendation and you really hit the nail on the head. I've used pfSense in SOHO environments without issues for years and thought I'd use it at home as my Draytek Vigor simply cannot cope with anything more with 220 mbit, I tried for 3 days to get the latest stable build of pfSense to work and had exactly the same issues with multiple xbox and Warframe. To make matters worse, Warframe on xbox does NOT let you change the ports it uses, only enable IPv6 for chat :( I believe the problem seems to be a poor (or buggy) implementation of UPnP IGDv1 with "miniupnpd". You can trick pfSense into mostly working by enabling PureNAT and restricting what addresses each device can grab through UPnP by adding an allow rule under UPnP settings, and then limiting one of the consoles to static port (leaving the other defaulting to dynamic), however even though we could play two games separately we could not join the same session. To make matters worse, when a party invite was sent, the sender received an invite back to themselves, weird :) I've abandoned pfSense for now and will be trying OpenWRT on x86/64 but I fear as it also uses miniupnpd it may suffer from the same problem. The only difference is OpenWRT is Linux kernel based whereas pfSense is FreeBSD based. For now, you've got a new subscriber, keep up the good work :)

[@darkpsion]

There is absolutely no need to forward ports nore enable upnp for any game with a server on the internet. The only way you would ever need to do this is if you are hosting the server or the game uses some weird peer to peer server but this is far and few between. Your router uses PAT and is a one to one connection to the server out on the internet thus another computer on your network will also connect to the same server successfully. The source port is generated randomly ensuring the connection returns to the correct source pc.

You should be commended for making your own custom router but it's good you're showing people why we need router companies to get on the ball and start offering this feature with hardware accelerated support. It's still experimental on routers that allow it so I cannot recommend it as a good options. More gamers would benefit from going in to their routers if they can and dealing with ethtool -c (coalesce) or -k (offload) settings and ensuring the bad ones are disabled and that you're packets aren't being held up. While I run games with cake on a R7800 netgear cake itself is only helping out problems on my end. Cake and FQ codel will not fix bad hops or problems on other hops. The tech is great but only if you're you have a ton of people on the LAN making Upload wan problems or you want to ensure latency/bandwidth in a situation of that nature. Openwrt offers you more be it a router or customizing you're own pc to do so. Ask dave or come to openwrt forums or contact me for help.

[@BattleNonSense]

The issue is the UPnP implementation in PfSense. I evenually moved to Untangle (see the later video). I also collaborated with Dave Taht and Sebastian Möller on this video. kzbin.info/www/bejne/gputiJKpasyEb7s

[@MikaelKKarlsson]

Fortunately there has been more consumer routers coming out with actually working QoS features over that last year. I waited for Ubiquity to come out with something semi-consumer that wasn't built upon an ancient processor, but grew tired and gave the TP-LINK Archer C2300 a shot. Very fast and excellent latency under load. Sure the config isn't too sexy, but home routers don't need that. It even works out of the box, though that's almost frowned upon by some people.

Hi. Why don't you try openwrt on an x86 machine? Works absolutely fine and it has fqcodel as well as fqcake!

[@BattleNonSense]

I as not aware that you can run it on x86 CPU's. since when is that a thing? :O I might try that, thanks!

[@bioresadent]

@@BattleNonSense I don't know for how long it has been supported, but I've been using it for a while as my home router with an Intel g3258 cpu and had no problems at all. I dropped it due to being overkill for my internet bandwidth but it got the job done just fine :) glad I helped.

[@leexgx]

@@BattleNonSense needs to have cpu support AES-NI or it not work (any low end i5 will blow away any edge routers included cpus) Interesting you had issues with upnp maybe the NAT settings needed changing or they fixed something to make it more secure but broke upnp, the problem with a lot of these router software people tend to be Linux programmers and don't really like UPnP and lock it down to the point it brakes stuff (or it's NAT setting that's making the issue) I use an Asus router running asuswrt-merlin that does seem to support a lot of options and most of them in hardware acceleration still also as you have some pretty powerful if not expensive routers that have full support for Asus Merlin because asus has the Source Code open (most of the settings keep it hardware acceleration on)

PFsesne leans more toward security than convenience so this isn't surprising. You do have to set up a lot of rules to get things working, but this also gives you more control over your network as a result. Set and forget out of the box, isn't the point of PFsense.

[@FreeRoamingHumans]

The root of the problem is IPv4. Its flaws already became apparent in the 90s, which is why IPv6 came to be. But instead workarounds like NAT and UPNP were invented to mitigate the issues with IPv4. Now while more and more ISPs switch to IPv6 (simply because they run out of addresses), the routers and modems they provide typically block all inbound traffic, because 'Inbound == bad'. So we inherit all the drawbacks of IPv6, most of which come down to lack of adoption, but gain none of the benefits. Rant over. Thanks for your attention.

when "enable UPNP" means "check here but do other things to get UPNP working"... *edit* untangle > pfsense.

I gave up on wireless and began using a powerline adapter. Keep in mind that it's heavily dependent upon the wiring in your house. If it's old as shit, you're out of luck. I was getting bufferbloat on wireless 2 feet away from the router. Doesn't matter how good your wireless is.

[@BattleNonSense]

true. sadly for powerline anything that uses a motor, or compressor (fridge) is an issue too - switching on the lights can be a problem as well - basically anything that causes high frequency noise as that interferes with the powerline signals.

[@FractalHalia]

wrong if you don't use airtime fixes which is linked here the difference isn't day and night it's like being in another dimension. arxiv.org/pdf/1703.00064.pdf Stop using busted wireless. This goes for any gamer on wireless who gives a damn.

Edgerouter Pro is still affordable for home use. What is the SmartQueue limit of Edgerouter Pro?

[@marciets1752]

I have the edgerouter 4. About the same as the Pro. I have 360/36 setup in Smartqos. Get 300/30 with these settings

[@kanarie]

200-ish. The ER-Pro is based on an old chip (ER-Lite/USG too), so you'll get better performance with the ER4. Currently shaping 300+170Mbit with "cake" on the ER4, but that's a load balanced connection so it can use a CPU for each line.

[@kwinzman]

I am lucky to just get a new 1000 Mbit Down / 50 Mbit Up connection. Can anybody recommend a smart queue router that can handle this?

[@kanarie]

You'll have to build it yourself probably, because shaping that kind of speed requires something fast like x86. Not even the dual core 1.8Ghz Linksys WRT32X has enough CPU power to shape 1 gbit.

hi, what program u said u testing and not have the problems u find on pfsense? i not have router just an old cable modem

[@bobhumplick4213]

an r6220 from netgear, used from ebay for about 25 dollars, is a great router for openwrt. good for at least 100meg internet with sqm enabled. maybe up to 200 meg. its a dual core at 800mghz and has 128mb of ram. you have to install openwrt yourself and setup sqm but its worth it and cheap

[@kanarie]

That's a great little router with the same SoC as the Edgerouter ER-X. I can confirm you can shape just about 200Mbit with it on OpenWRT and cake.

[@Skanic]

Does the Edge router also work with a 4G modem/router?

[@LongTimeAgoNL]

Hi Battle(non)Sense, Due to your BufferBloat video last year I decided to do a bit of digging as I also suffer from that issue. However... I bought a 'probable' solution and I'm not sure if it will work, but according to some users it should be better. Due to me being in the Netherlands and having Ziggo as a provider I am 'locked' to a router. I need to have the router/modem combination in my network, that only hosts 4 ports. This thing is so poorly optimized for anything other than streaming and TV signals, your gaming connection can vary from very low pings, to massive spikes that the game does not register immediately as they are really short, only when a user starts to watch netflix or when a device starts to download a massive update or sync its files. But I bought the NetGear Nighthawk S8000 and will connect all my wired deviced to this thing as it has QoS and other "pro gaming" network features. Is it possible you can test these so called "Gaming Switches" that have QoS to enhance gaming network performance?

[@BattleNonSense]

Sadly QoS as sprovided in most consumer hardware is garbage, especially when it comes to switches.

[@Ristogod]

I was going to build a pfsense router with some old hardware until I saw this. Now not so sure. I have a ER-4 today on a 400Mbps connection, but was hoping to go to a 1Gbps fiber option in the fall. What would be a good replacement for the ER-4?

[@ltonchis1245]

OPNsense is the alternative and I think someone mentioned about a package for better qos of gaming

Gotta admit my pfsense box likes getting fussy on certain games with upnp, but i read the title as pfsense with codelq not working? But your problems were with UPNP?

Hello Chris, great video again! I've been trying to fix this problem for a long time. I have a 200 Mbit/s cable connection (Vodafon Germany) and when running the speedtest, I immediately get bufferbloat over 1000ms. Online gaming sucks on this connection but it's the best i can get here.

I don't have much experience with those features. Any advice you can give?

I used to have a cable ISP line in the past as well. I had quite a lot of issues running games on that line due to packet loss and high jitter. I had used a Fritzbox 6430 as modem/router/gateway. Prioritizing ports didn't work for me either. Changing to another ISP with VDSL2 was the one and only solution for me.
