For the dynamic DNS issue, I use Duck DNS, which is free and lets you update your IP with a simple curl call which you can execute in a cron task. This way, you'll always have your IP up to date.

[@sophiophile]

I'm sure someone like Jeff owns his own domain. If he hosts the primary NS himself, it's easy as pie. If it's hosted by Google Domains, also easy as pie.

[@jan_harald]

@@sophiophile well, not easy as pie exactly, self-hosted, you would need to set up some way to actually update that, which would probably mean setting up stuff like TSIG keys and whatever, and then using those keys on the machine updating the records, and such...but yeah, it's not that hard either, and most dns hosting services do indeed have pretty easy APIs

[@miniskulljob]

@@sophiophile he said in the video that he uses a vps to send the IP to it, and then manually change it in the DNS records of his domain. Also, I don’t know why are you telling this to me. I just shared an option that I think it’s quite good, like many others shared their own options.

[@jan_harald]

@@lidbergtech neither cloudflare nor zerotier can be self-hosted, lol but sure, it's easy to use one of the many ways to get the job done, if you don't care about that and do note we were talking about "If he hosts the primary NS himself", not "how can it possibly be done"

[@StooStranger]

I use Google Domain + DDNS on my Edgerouter, now same thing on my OPNSense box. Pretty much plug and play

[@thebeatconnect1]

For people with CGNAT, what you can do is setup a VPS as the middle man. Setup wireguard onto the vps and on a device on your home network, and you can setup wireguard on the vps to forward requests or ports to your home network. This is basically what services such as tailscale do. I use this setup to host a mail server on my local network. No need to open ports on my network

[@sporqist]

This. Relatively easy to setup, you can host servers literally anywhere* as long as there is internet and it's super flexible. Just remember to have the clients keep their connection alive so the VPS is allowed to talk back to them.

[@cvetelingeorgiev1527]

What if I have a corporate network with public static IP and I want to establish a VPN between that and the LAN network of a 4G broadband router behind CGNAT. I need to access an IP camera in that 4G router's LAN

[@MiguelSantos-wp1ym]

Or just use IPv6

[@GreenCinco12Official]

One thing to add (especially for macbook/iphone/ipad, not tried it on windows/android): If you still want to use your private vpn for security reasons (like public wifi) you can enable "On Demand Activation" in the client. Then activate whatever you need and set your home wifi SSID as an exception. This way if you have enabled the vpn profile it will automatically connect to your vpn whenever you're not at home (depends on your configuration). Really helpful if you have public wifis that are set to automatically connect and you are in range without knowing it. You have to disable split tunnel (or change the allowed IPs correct) but I'm not 100% sure how to do that at the moment. I suggest you create a second profile for it but importing the same profile a second time works when you name it something else.

[@jordanmccallum1234]

If you need a privately hosted VPN and must be behind a CG-NAT, your best bet is to set up set up a one-to-many IPSec tunnel with NAT traversal. It'll require a bunch more setup & understanding of networks, so for most people Tailscale & Zerotier are better, but it can be done. Also minor thing, no RaspberryPi has cryptographic extensions, which is why it's so slow. If you need more speed it's *possible* you've got a router with AES-NI instructions, otherwise your home PC, old laptop, or an SBC that's a little beefier than a Pi would do the trick.

[@-argih]

Tailscale have been working wonders for me, is technically an overlay network but is using wireguard under the hood, they have clients for Truenas (using the truecharts repo), OpenWRT, PFsense and even there are some experimental clients for RouterOS (mikrotik). I'm limited by my 10mbps upload speed but the overhead is not so much so I can stream 1080p content without transcoding.

[@francocastilloAR]

WireGuard does not take advantage of AES-NI.

[@enochliu8316]

Wireguard does not uses AES, but ChaCha, a cipher that works faster on this machine. It uses ARX instructions.

Good video. It would have nice to also cover local dns resolution. Especially from mobile clients that's handy. And a comparison to other options like zerotier would have been nice, too. That should be enough content for a 2nd video :)

[@CarMaintenanceGuy]

I already had Pi-Hole installed. I followed this video after pausing, replaying at a slow speed to see what I was missing. I was able to get the VPN running perfectly on my Pi 4 Model B with my Samsung 22 Ultra. It worked so effortlessly on the first try. Now I can use public wifi and not be worried about people monitoring what I an doing. Thanks for posting this video.

[@christiansantiago3007]

Very informative. Been looking for a new use for the Pi 4 that used to be hooked up to my tv.

[@danielberglv259]

I am behind NAT and use Windscribe to deal with this issue. They offer port forwarding and can be a great alternative to dealing with NAT. I run Windscribe in a Docker container and Wireguard in another container. When I need to connect to my home network, I connect through the Windscribe IP to get into the Windscribe container which is then setup to forward the connection to the Wireguard container. It does of cause provide a bit more overhead because you are basically nesting VPN connections, but I have not had any issues with my use cases.

[@JohnArnoldUK]

And just like that something I'd been meaning to set up for years was done thanks to this video. I was hoping to waste a whole afternoon setting this up but annoyingly I was done in about 10 minutes. Thanks Jeff!

[@thewebmachine]

1:36 traceroute can also show more than one hop if you are using a separate router from your ISP's modem. In that case, you'd likely see two hops, one of which is the router in front of the modem.

[@JeffGeerling]

Ah true. So not a bulletproof method!

[@thewebmachine]

Indeed, but if you know enough to put a 3rd party router in, you likely already know enough to figure that out...or setup the VPN on your router and eliminate the need for a separate VPN server. Of course, router VPN servers tend to be a bit slower due to low end SoCs, but if you are already on a woefully asymmetrical ISP (I really hate DOCSIS for this), this won't likely matter much and will be similar to your upload speeds, anyway. Still a great video for the average not-as-techie power user! 😎

Tailscale's great, but as Jeff's clearly wanting to do this without any third-party cloud help -- other than his ISP, his DNS provider, his VPS provider, etc. -- it's fine. After all, Tailscale is built on Wireguard, and is really a cloud service to make configuration and discovery easier. I have both.

Jeff, I saw that you have some variant of an Asus router, you should be able to run Wireguard right on the router from the VPN tab, I'd like to see a video on that

[@benargee]

Will you be making a more in-depth video about tailscale? Also with the inclusion of self hosted orchestration using headscale. I see you gave it a shout out at the end. I've been trying it lately and it's handy. I'd like to see your thoughts on it as well as your ideal use cases. It works great with pikvm too.

[@JeffGeerling]

Possibly. Since I only used it once and don't run it right now I'd need to do a bit more work for that. Might do either that or Cloudflare Tunnel.

[@amrrahmy123]

well there are a lot of solutions. I usually just have anydesk and teamviewer setup, but for software projects i have done, in case of ip changes, instead of manually changing the ip after getting a notification, you can change the domain or subdomain settings automatically, i am pretty sure namecheap has an API you can use, not sure about other providers/registrar, but it was fairly easy to create a small service/program to check and update the ip from local device. In case of mobile data, the device behind the network can connect to a cheap-ish $5 or so VPS, and the other computers can connect to that server to create a network. tailscale i wanted to test out but didn't have the time.

[@neiltrotter5933]

Thanks for this Jeff. I've been ssh-tunneling in for years (which works), but I promised myself I'd tidy it up a bit one day. PiVPN will probably work for me, as I have a couple of Pis already running Pihole & unbound, so this video will help me with that. But man, either I'm getting slower with age, or you're speeding up! It's OK, I'll just have to pause a bit more often so let the info sink in :-) I also plan to move to DuckDNS for DDNS, as NoIP (free option) grinds my gears each month by threatening to expire.

[@Razor_Burn]

Fantastic tutorial and safe travels! ❤

[@postnick]

I ran PiVPN for a while but I think work was blocking that port or domain - so I switched to Tailscale and used my home PIHOle as an exit node and it's been much eaiser. But Your point was no 3rd party software so still a great video! I do like how you can use local IP addresses on pivpn but not tailscale.

[@NightHawkATL]

I have been running Pi-VPN for a month now and it works better than the pfSense implementation. I was able to get a full tunnel connection almost right out of the box. I just had to add my Pi-VPN IP subnet to the outbound NAT and voila. I will add a domain redirect to it soon. Since I have cloudflare, I can use the cloudflare ddns updater to update my IP if/when it changes and it will automatically update my records for my domain(s).

[@adirgan]

With zerotier you can also create a tunnel with your network, and with some configuration, you can even use your internet, and it doesn't matter if you are with CGNAT

[@_arhamgamingoffcial]

Your video 's great useful. Thank you so much !

[@lucasew]

I think that software defined vpns such as zerotier or tailscale are more convenient. They, for example, suport internal DNSs and by default only route the relevant traffic through this virtual network. Tailscale has a exit node thing to allow routing everything to that exit node machine just like a classical VPN.

[@Nik.leonard]

I do basically the same, but I use OpenVPN on port TCP-443 for sidestepping the restrictions on corporate firewalls. I tried to do the same with Wireguard but Wireguard is UDP only and UDP protocol is locked in some corporate networks. Amazingly, I can even play games with Moonlight or Steam Link with only 10ms added latency from my work or other people houses (in the same city. I haven't tested that from other cities). My internet provider is FTTH with 800mb/s Symmetric without CG-NAT so bandwidth is not an issue.

[@lyonn5]

Couldn't have asked for better timing on this! This is a lot of what I want to do so I can administer my parents' HomeAssistant RPi that I'm going to set up

[@Newtype2259]

Does the connection persists/reconnect and do notifications from hassio still work after it loses the vpn connection? And does it automatically connect to the vpn when i leave my home? I’m still on the fence if i should use this or a reverse proxy.

[@snekulcire]

I have 1gig symmetric fiber. My PiVPN on a Pi4 using WireGuard is usually able to push 600-700 mbps to another computer in town with a decent gigabit connection. Sometimes I can get faster and it seems that messing with the CPU governor has some impact, as does overclocking. Back when I used OpenVPN it usually was around 200 to 250 MBPS. If you're upload speed limited on most cable ISPs, it'll probably be able to run at that max speed no problem.

[@JohnWhittle]

Very helpful video thank you!

[@DIYDaveOK]

Amazingly timely video! I literally just started setting up self-hosted VPN last night. Got a personal domain + DDNS working, then set up OpenVPN thats baked into pfSense.....just having trouble with the exported profiles connecting back...

That was my trouble with OpenVPN - and which is why I decided to flip over to Wireguard. The app worked a little more seamlessly (didn't have any weird issues).

[@DIYDaveOK]

@@JeffGeerling Well my VPN logs show an error regarding a missing HMAC that suggests a problem with a key definition in the exported profile, so I'm hoping I just missed some detail in the profile definition. And I'm in EXACTLY the same boat you are with asymmetric cable Internet (I'm stuck with awful Cox), 1 Gbps down but 40 Mbps up 😡

[@balls2bone]

I also run PiVPN, but on a Orange Pi PC running Armbian. Had no problems with it so far! It is limited to about 12Mb/s, but that's fine. My home up speed is only 25Mb/s anyhow! But as a bonus, it uses 250mA at idle!

[@korishan]

Jeff mentions that behing CG-NAT you can't use a dedicate IP address. I get around this by using CloudFlare and their tunneling application cloudflared. It creates a DNS entry automatically (if you have your DNS hosting with them, otherwise you have to manually register with your registrar) and then you can use that name to connect. My ISP is Xfinity/Comcast, which definitely uses CG-NAT on multiple layers, I can access RDP, TrueNAS, PVE & Hosts, File shares, etc. The only thing I've had issues with is actually setting up the VPN portion so that my phone uses that instead of its routing. This I think is partly due to cloudflared does not current support UDP connections

[@TK-vh5pv]

[@pdx2240]

I have the exact same Router as Jeff Geerling, - ASUS RT-AX86U, where you can run a VPN server on that device, thats both faster, and easier to setup than PiVPN, supports wireguard and DDNS. Also the router is already an always on device. Though before I have used PiVPN on a pi for many years to solve this exact problem, and it just works!

IPv6 support globally still sucks. Yeah if it works it's great, but it's better to just always assume you're not going to have IPv6, especially when traveling abroad. Been waiting 20 years for IPv6 to go mainstream, reckon I'll be waiting another 20 lol You could implement both an IPv4 and an IPv6 VPN, but I always just target the lowest common denominator to accomplish what I need.

@@BrianCroweAcolyte Yes. My home VPN will use IPv6 for the tunnel if it's supported and will pass both IPv4 and IPv6 through the tunnel, but it seems to be extremely rare that IPv6 is supported in public places that I connect from.

YMMV, but I've found, in the states, that IPv6 is available and works in most places that i am, with the exception of retail wifi (most specifically a local chain of coffee shops that i frequent). My mobile provider (T-Mobile) def has working IPv6...in fact, their network is v6 *only* with an adaptation layer on top of it to make v4 work. I use v6-only for my personal setups almost completely because it ends up being *easier* to work with.

Plus it is absolutely free for private usage. If you want to setup your own server for Tailscale you could even do that with headscale. And is is also based on Wireguard.

I use Wireguard to route public IPs back home just out of spite of my ISP's horrendous international routing making it impossible to work from home, since I need to route at least 1Gbps down and up simultaneously I opted for an older i5-4590 based desktop but it works really well for my use case. It's a bit different from yours but this is another legitimate use case for VPNs.

It uses Wireguard under the hood, and "users" are "external clients" and get a standard Wireguard config for a specific ingress node I define. The other nodes in the VPN run the Netmaker client, and form a mesh that is entirely (or nearly) configured by the Netmaker UI. I wonder if I could share my server with others and not break my security. Heh. The server just does config and such generally.

[@MackyClemen]

'tracert' is probably a bygone era of Windows that does not have long filename support as 'traceroute.exe' would be longer than the 8.3 format for filenames

[@ondrejlol]

According to my testing, Pi 4 is can handle up to 300mbit through Wireguard (Internet connection is 1000down/500up). OpenVPN is much worse (like 150), if you need more, you have to run the VPN server on something more powerful.

[@JeffGeerling]

Yeah, the most I got internally through lan was around 270 Mbps, so that checks out!

[@dadrad]

If I'm remembering my history, the abbreviated "tracert.exe" probably had something to do with the 8.3 filename length.

[@marketuser6478]

It's tracert because of DOS's character limitation of 8 for the name and 3 for the extension.

How much easier this would be to follow (and use) if it weren't a KZbin video, but written instructions. Thanks, Jeff.

[@JeffGeerling]

Boom! Thanks for posting the link, saved me the hassle while I'm flying home from UK

[@BrianG61UK]

I run my home VPN on my router. It's a Ubiquiti EdgeRouter X. You can do lots of interesting and/or useful stuff with it, but it's not simple to use.

[@louwrentius]

Hotel WiFi often blocks UDP (except for DNS). Only 443 TCP is reliably “open”. The lack of support for TCP is a downside. OpenVPN is not as fast or easy to setup, but at least I can trust it always works. Maybe you can use DNS or an NTP port for your WireGuard server, or maybe another common DNS port that is likely permitted, even on hotel Wi-Fi?

[@Smytjf11]

Have a good trip! I'm pretty sure I need a virtual VPN. Each VM gets a bare metal GPU. Pi gets to be an orchestration manager. I'm willing to accept that no Pi will host a GPU but it can orchestrate them no problem 😒

[@JoopKomkommerShake]

Use ZeroTier if you have CG-Nat, works fine without any hassel. ZT works also fine without cg-nat.

[@WilliamCollier]

Pro tip if your isp is AT&T. Even on a consumer accounts they will give you a block of static IP’s for $15 a month!.

[@mina86]

One option to deal with IP address changing is to setup a TOR hidden service which can serve as a backup if your IP changes.

Hey @Jeff Geerling, I don't know if you know, but your Asus Router... actually provide hosting OpenVPN server in it's firmware

[@easteregg8699]

to work around a dynamic ip i just portforward via autossh to a small vps :)

[@Scranny]

Jeff, can you share your script (the one you run by cron job) to update your current dynamic IP to your personal VPS?

[@iamrage4753]

Jeff, great video, just wondering could you consider covering gluetun + wg-easy how you set that up for site to site wireguard that passes traffic to VPN provider using gluetun pls?

MikroTik routers have WireGuard and DDNS built-in, so you could use your Raspberry Pi and/or other computers for better tasks… 😉

[@chrisostapovitch6567]

That GI Joe PSA got me. I used to watch those growing up lmao!

[@andiszile]

Also MikroTik ROS v7 supports Wireguard :) So you don't even need separate device

[@Ian1957a]

Hi Jeff, My Asus router has a VPN server built in. I notice you were using a Asus router any reason why you don't use the VPN server in that. Great video as usual, thanks

[@mattwhite532]

Thank you for the video Jeff. Is there a way to get this to work in places that block VPNs like airports or hotels? I know for Captive Portal you can just turn off Wireguard while you connect, then turn it on, but if that doesn't work, how can one stay private and secure if the system won't let you? I don't believe Wireguard has a way to utilize obfuscation, right?

[@alexlandherr]

Maybe I’ll look into this; would help me manage my future Plex server from my vacation home via SSH.

[@anonylesss]

i've been using Wireguard before it was part of the Linux (5) kernel and it's superb. just like you, my home IP changes every now and then (or every time I manually disconnect it..) . my weird solution is a Telegram bot which responds only to me running on a Pi, that sends me the home IP address. the library i'm using called Telepot , it's very old but works well

[@yourt00bz]

Can’t believe you were close by enough to have a beer. DAmn maybe next time

[@anthonywong-sq2jt]

Hey Jeff! so glad you made this video. ai have been looking for a while now for how to obfuscated the vpn connection without having specofoc devices. I know I can use wstunnwl with linux but I camt do that with ios. can u make a tutorial if possible?

[@farzammaghouli-kp5cr]

idk why i get this suggested after i struggled for 5 days, i made it but now i find this guy

[@csolisr]

My newest ISP doesn't offer an open public IP, so I had to rent a VPS specifically to allow my home computer to be accessible to the world - using precisely this method

[@trevorphillips9220]

If you have a Fritz!Box Router, you can just enable Wire Guard and you got your vpn in a few seconds.

[@ckennylin717]

Can't help but notice you have an Asus router. The newer firmware on the AX models have Wireguard built in. If you do have a Wireguard-capable Asus router (stock or Merlin), how does the admin and performance compare to PiVPN?

[@ElsiervoDePeFKNerre]

Me encanta como describes todo y ni se diga tú gran sentido del humor mezclado con sarcasmo es la combinación explosiva y voy a ver si encuentro ese video que cuando mencionas 6:18 pero lo encontraré , saludos desde el Mar Caribe 🇵🇷

[@mabs-O_o]

Also, ZeroTier as an alt to Tailscale, client and server are FOSS if you want to run your own

[@elminster8149]

Welcome to the UK Jeff!

[@JeffGeerling]

Ha, as I'm typing this, I'm actually on the plane departing the UK! Just didn't have time to finish up the video until last night :)

[@tesleigh]

CGNAT Starlink workaround: Starlink Router in Bypass mode, use a third party router with IPv6 support enabled in the settings.

[@mstrickk1]

I use the free no-ip. Respond to an email once a month to keep it active. Both my asus router (as an AP) and my erx router have the option to use no-ip. Even if yours doesn't, the Windows program works flawlessly.

[@BrianG61UK]

I always use a non-standard port for my VPN servers. It just seems silly not to add some extra security at no extra cost.
