Use DD-WRT to set up a VLAN and Virtual Wifi for IoT devices

[@DataRebelYXX]

FINALLY - someone who actually can talk about home VLANs without mentioning Ubiquiti. I do have one question though. Is it necessary to reserve an ethernet port on the router for the IoT VLAN, or can you just do it with WiFI only? I don't have any ethernet IoT devices (all WiFi) so I wasn't sure about this point. Thanks -great video!

[@DevbaseMedia]

I havent done a wifi-only IoT subnet personally, but I believe it should be perfectly possible. You would associate the virtual wifi with the bridge you've created for the IoT network. So, you'd still create the IoT bridge, you'd just skip the step in the video where I assigned the LAN ports. Again, haven't done it personally, but try it out :)

[@ZtowhyA]

still works for me all Virtual AP same concept.

Fantastic Video Chris. It worked like a charm on my 3200WRT on my first shot. Thanks a lot for making the video and explaining so well. Want a challenge? Demonstrate doing the exact same thing using OPNsense (or pfSense) on a 6 port Protectli vault. Because DDWRT development seems to be stalling, particularly with WiFi 6 - I'm being forced into the xxSense wilderness. A pity as DDWRT is the work of Gods!

Wow. Concise, to the point, exactly what i was looking for. Thank you.

[@KcinRekab]

Absolutely amazing tutorial! Straight to the point and easy to follow along with. The only issue I was having is that the IoT VLAN didn't have access to the internet. I could connect to the WiFi network and communicate with local devices just fine, but I had no internet access. After some troubleshooting and forum reading, I found the fix was to go under Setup > Networking > and then all the way down under, "Network Configuration br1 - IoT Network" I had to enable, "Masquerade / NAT" and then I had internet access! Hope this helps someone who may be experiencing the same issues

[@csmath]

Thank you so much for this great video! The issue I was having that made me seek out this video was that trying to change the switch config would either disable internet access or LAN access completely. I ended up just restoring to factory settings and starting from scratch. I'm running r48971 on a Buffalo WZR-600DHP2, so my config pages looked a little different, but other than that I was able to follow along. One thing I noticed is that my switch config had the LAN ports on VLAN1 and the WAN port on VLAN2. I didn't want to mess with it again, so I just created VLAN 3 and it worked like a charm. I'm doing WFH, so it'll be nice to keep my work computer (and IOT devices) separated from the rest of my network.

[@aanm7]

Found a cheap Cisco Linksys E1200 v2 at a Renaissance, 5.25 $CAD ; installed dd-wrt (can't get the exact version I installed now, but was June / july 2023) and setup was similar to this. It's key to do CTRL-Shift-R to refresh and ensure settings were saved as many times the UI won't reflect the real settings. Also the VLAN (Switch) page in the video doesn't show a CPUPORT checkbox that need to be enabled for all VLANs, for the ports to work.

[@AwesomeOpenSource]

Really Excellent. I've been looking at DD-WRT after being away for a while, and I want to use it to replace my Eero Mesh. I see some tutorials on setting up Mesh with DD-WRT, and I would love to make sure there's also VLANs that I can setup, so thank you for this. Really great stuff. Subscribed.

[@greatestunknown]

Thumbs UP! Just what I was looking for. In my case, my cameras don't even need the internet, but I can handle that leveraging off of the firewall script.

[@verygoodbrother]

I have a pfsense firewall already. So if i set the router running DD-WRT into AP mode will the VLAN function still work? Essentially for my scenario, the WAN in your setup will act as a trunk access and pfsense will manage the firewall rules?

[@nathanielkswas]

Thank you so much! I wanted to repurpose my TP-Link Archer A7 for IoT instead of purchasing Ubiquiti and this solves that problem wonderfully!

[@rafalboni3595]

Thanks for writing this up! I had a slightly more complex use case (secondary AP behind main DD-WRT router) and wanted to VLAN all the IoT devices which connect to the secondary router. Once I realized that STP config was causing ports on my core switch to get disabled (because I had STP on on all the bridges on both primary router and secondary AP, likely with default priorities, etc. so that probably looked like a loop to the switch), but eventually got it working. It's worth noting that versions of DD-WRT v3.0-r48646 (on routers with enough flash) also have the ability to reflect mDNS between different networks, which can help put even your Google home / Alexa speakers on a VLAN... in my case I also needed that to isolate my ESPHome devices from the LAN where the Home Assistant system sits and still be able to access them via HA.

[@francoisgirard6725]

This was a superb instructional video - thanks for taking the time to make it! I am struggling, however, with WAN/Internet access from the VLAN and VAP. I must be missing a route, bridge setting or some other parameter. Even if I remove all of the IPCHAIN firewall commands, and if I run traceroute, there doesn't seem to a route to the outside. What have I missed? Found it - you need to enable Masquerade/NAT under the Setup->Network Configuration for br1!

Hello , what build are you running? I have 47495 and after i create a bridge ,even if i create a firewall rule or not , asign an interface to that bridge or not , my wan network show that is conected , by have no internet access .

@DevbaseMedia As far as I can tell, I've got your solution working (thankyou!), but I was hoping you could help with a couple things? First, oddly, I cannot ping (from a terminal/cmd) anything on br1 from anything on br0. I can however remote desktop from br0 devices to br1 devices, so I br0 can obviously talk to br1... just not ping it (also cannot remote from br1 to br0, so that seems to work as desired.) It's a small thing, but make me very curios why? Additionally, the GUI has changed quite a bit in the newer beta versions. Wondered if you'd consider doing an updated video? Was hoping the newer interfaces would allow you to achieve the same result using the gui - maybe tagging? - without the need to manually write the firewall rules?

[@huskyman20435]

Thank you very much! :) I will get going right away, been searching around and there is a lot of older video's.

@@DevbaseMedia After setting up the firewall, should I be able to get to 192.168.0.1 or 192.168.1.1 from the IoT wifi network? From what I can see, I can't access any device with 192.168.0... except the router's admin panel. My router is behaving a bit strange. Do you know any solution? Thank you in advance for your answer :)

[@DevbaseMedia]

What I have noticed is when I'm on am IoT subnet, I can only get the admin console from the subnet ip address (if the firewall rules are in place, that is). In the video example, when I'm on the 192.168.107.x subnet, I can get the admin console at 192.168.107.1, but I can't get it at 192.168.1.1 (because the firewall rules restrict my ability to see the main subnet).

[@połpołowiec]

​@@DevbaseMedia For me it works weird, because when I am on subnet 192.168.107.x I can reach the dd-wrt admin panel with the address 192.168.0.1 and 192.168.107.1 but I cannot reach any other device for example 192.168.0.2, 192.168. 0.4. Could you post a link to the forum topic where you got this config?

[@DevbaseMedia]

Hi. The 107 subnet *shouldn't* be able to see any other devices - it should only have access to the internet (so it's totally isolated). With that said, there is no reason a subnet needs to be restricted like that (you are right it's enforced by firewall rules). Here is the original forum post where I explained how I did my VLANs, and the helpful reply for the firewall rules. Note that my *media* subnet (192.168.50.x) was specifically set up to have access to the main network, that is possibly what you are looking for: forum.dd-wrt.com/phpBB2/viewtopic.php?p=1212560#1212560 Let me know if you need more info

[@eddyl.8478]

A very useful video! I followed your steps and successfully created an IoT network. With the iptables commands you advised, a device in the IoT network (i.e. 192.168.107.*) is not able to ping all the other devces in the 192.168.1.* network.....except 192.168.1.1. In fact, 192.168.1.1 is the same as 192.168.107.1 so I would not be surprised if devices in the 107.* network can ping 192.1.168.1. However, I found in your video that you was able to block the traffic from 107.* to 192.168.1.1. I wonder why and what caused the difference. I will keep searching to find a way to block the traffic from 107.* to 192.168.1.1. In case you know what caused the difference, please advise.

[@pedropaiva6067]

maybe somebody will know better but I think that is something to do with the fact that 192.168.1.1 is the gateway for the vlan, maybe there is a way to create another ip address for the same router in the 192.168.107 network

[@blanked_out_chin]

Do you think setting up a managed switch with VLAN is enough to keep IoT devices from talking to trusted devices on my home network or would I need to have a firewall setting? my setup internet>router>managed switch: port 1 (router), port 2-4 trusted devices, port 5 (another 5 port unmanaged switch of IoT devices)

[@paddle_shift]

As your IOT devices are on SSID network dd_wrt_ IOT and your trusted devices (like your phone) would be on SSID dd- wrt, in order for you to "see" or in cases where you needed to update an IOT device, would you have to switch out of of dd-wrt and get into dd-wrt-iot to see it? Or does this "virtual" lan be visible when you are attached to dd-wrt?

Well, I would like to say very, very interesting for sure I do like solid security however it will take sometime for me to configure these settings however I'm more interested In the wireless settings for now. Are The wireless interfaces and virtual interfaces under wireless settings similar ? One more secure that the other? I would like to put my Amazon Fire Stick on the wireless virtual however I keep it hidden from broadcasting (maybe being more secure) but it will not connect that way since hidden. Amazon device wants to see the device to connect to it I'm not sure if this would be wise move or not. Is there another secure way to keep streaming device in their own WIFI zone I guess separate from others? Thanks for the video.

[@Sleepless4Life]

Hey! So if I wanted to create a vlan just for Wifi for my security cams and untrusted devices, do I have add new passwords and SSID again for that particular vlan after set up? My cams are annoyingly to set up wifi on. I'd rather keep those settings on the cams and then change them on my main wifi network for trusted devices. For extra security. But what if I keep same SSID/password on both networks will that be worse? Just askin', I rather not change anything besides two separate networks, but I will if I must. Sorry if this is super simple. But this vid was exactly what I needed. Very good!

[@skeetabomb]

I think that designing DD-WRT so that you have to apply IP addresses and DHCP servers to 'bridge' virtual interfaces is counter-intuitive and potentially quite confusing. It would also be very helpful if there was a set of commands made known that would help anyone with a DD-WRT device discover the interface stack and full Physical to logical mapping (layer 1 to layer 3 via layer 2)

[@marcsoubliere6186]

Most importantly, thank you. Plugging into the new vlan port initiates a new subnet ip, however putting the connection back still recognizes the device/computer as that new subnet ip, that is until the provided firewall commands are applied. (My router ASUS RT-AC66U)

super helpful! like and subscribed. i have just one question: i’m reconfiguring our whole home network for better security. other than changing my wireless router to dd-wrt, i’ll be adding a managed switch to hardwire as many devices as possible. it may not make a huge difference but i can’t tell if it is better to set up the VLAN for iot on the switch or on the dd-wrt. do you recommend one or the other? as far as i can tell, the only advantage to doing it on the dd-wrt would be for the virtual AP. on the switch, i would need a second physical wireless router. thanks again!!

[@DevbaseMedia]

I'd test speeds both ways. I don't have any managed switches, only unmanaged switches, so for me, putting dd-wrt as the principal and putting an unmanaged switch on the IoT LAN port made sense. Another consideration might be whether you want to use many additional features of dd-wrt. I have another couple of videos on setting up OpenVPN and Wireguard servers. If you end up wanting to do that, you might consider using dd-wrt for your main (DHCP) router.

[@NormRasmussen]

@@DevbaseMedia Right, DDWRT has a ton and ton of great features. I’ll go check out your videos. And I like the (obvious) idea of basing the decision on speed. my only hesitation with not utilizing more ddwrt features is making it a bottleneck with too much going on. thanks for the reply!

I managed to stop the IOT network from communicating with the private network but setting the IOT WiFi up as per the video I cannot access it, just keeps saying "wrong password" The only way I can connect to the IOT WiFI is by deleting the bridge assignment from br1 to wl0.1 then setting up a separate DHCP server for the WiFI. Then I can connect a WiFi camera to this network but if I have my laptop connected to the VLAN I cannot access the WiFi device. I assume this is a firewall issue but I am not sure how to fix it. It appears that when the br1 to wl0.1 is added no IP is given to the wireless client which I think then stops it from connecting.

hi, I ended up with 2 routers and I wanted them for IoT and home usage. However I have a dilemma: most (if not all) of my IoT devices talk to my local home assistant server as well as local MQTT server. So for the sake of being able to talk, home assistant also has to be in the IoT segment, right? If so it means: my HA will be also in insecure segment. On top of that, my HA is also talking to my home devices (other servers). So I think I need another solution. What I however did is: all IoT have internet access blocked (anyway, all of them are controlled only from HA and only with the local integrations) - I am thinking: do I need then 2 segments (for security purpose) or not? If YES (2 segments still needed) then how to solve the issue of HA being accessible to IoT devices, yet not being exposed?

[@TheKauff]

I was in a similar situation & got it to work by adjusting the firewall rules to allow access to my HA IP Address. Caution: remember, your HA doesn't use a default HTTP(S) port. Sadly, I don't have the firewall commands anymore, or I'd pass them along.

[@zyghom]

​@@TheKauff Yeap, I think I found a solution: 1-outer router for IoT, 2-inner router for home devices, including HA, 3-port forward from outer to inner only for specific ports - everything else blocked. I am yet to test it as I am not sure about which ports (for sure HA http and MQTT) and what about autodiscovery

if you're on new firmware, have you got the LAN CPUPORT box checked for your IoT vlan? So you need the 'LAN COUPORT' check-bock ticked for every LAN vlan you setup (but not on the WAN row, obviously. that should have the 'WAN CPUPORT' checked.) NB: this will also automatically setup vlans, which is handy. I'm using DD-WRT v3.0-r52330 std (04/14/23) on a Linksys WRT1900ACSv2. Side note, if you are using the same/similar router, I found that the port-mappings are actually backwards in the GUI... so for me, Port 1 in the GUI is actually the port 4 socket on the hardware.

However in my case updating to the firmware to v3.0-r47900 std from 12/20/21 fixed my issues. Although I did have to do a factory reset after upgrading.

Wish I would have had this video sooner, guess I’ll try it with my new nighthawk.

thank you.. great video

I have a different goal in mind. I don't want untrusted devices to connect to the internet at all, hardening the home network. I could have a have a baby monitor to keep tabs on kids when I'm at work. Kids being kids might sometimes be inappropriately dressed for company as they walk through the house when no one else is home. Or perhaps I have an IP based security system. Either way, I can't be sure these devices don't have built-in hacking programs that might be able to capture local IP and Wi-Fi traffic for the purpose of masquerading as another device by switching the other device's MAC address, and SSID if the other device is Wi-Fi. So, I want multiple vLANS, one for each untrusted device and filtered so that only that device's MAC address can communicate. For the Wi-Fi devices, a unique hidden SSID + password + MAC filter for that device is routed to a unique vLAN. Each Wi-Fi SSID needs its own MAC filter as well, so only that device can connect to that SSID and only that device can route to the assigned vLAN. Then a routing table to allow an NVR on the main LAN to communicate with any untrusted camera vLANs, and to allow a security controller to connect to any security devices on the other untrusted vLANs. Is it your impression that DD-WRT can do this all in a single router, or will it need two routers, one for untrusted devices.

I tried this and it works but the wan port is no working as well. Does anyone knows how to fix that

[@cwizzy13]

Thank you!

[@geniusarunesh]

I am running latest dd-wrt firmware , vlan works well and ip address issued as set but still vlan on br1 can ping comfortably system on vlan linked to br0 , have used entire set of commands as shown and for denying iptables -I FORWARD -i br1 -o br+ -j DROP

Thanks for the video.

Hi! Thanks a lot it was ver helpful

[@billrob9464]

Thanks so much for the informative video. I was able to flash my Asus router with DD-WRT and assign the VLAN to port 4 and all the IP addresses work great but I can still ping 192.168.1.1 from 192.168.107.1. I used the command lines in the video for the firewall but it appears the firewall still also traffic between the two subnetworks. Any ideas what I may have missed or causing this? Thanks….

[@BloodShotChrome]

Yeah I'm wondering about this too. Perhaps In order for the VLAN to function a connection has to be established with the DDWRT router and the commands the forum user posted assume any attempts to breach the router will be shut down by the SP1 firewall? Just my guess.

[@DisasterousRDX]

Yeah, I had the same problem. Router's management console was accessible from both IPs 192.168.1.1 from 192.168.107.1 from IoT network. I think even if we block packets to 192.168.1.1, we won't resolve the vulnerability to router's console. A workaround I used is to add below lines in firewall config to block access to router services from br1. #Block guest access to router services iptables -I INPUT -i br1 -p tcp --dport telnet -j REJECT --reject-with tcp-reset iptables -I INPUT -i br1 -p tcp --dport ssh -j REJECT --reject-with tcp-reset iptables -I INPUT -i br1 -p tcp --dport www -j REJECT --reject-with tcp-reset iptables -I INPUT -i br1 -p tcp --dport https -j REJECT --reject-with tcp-reset

[@BloodShotChrome]

@@DisasterousRDX Thank you for this! The programming of firewalls is something that has always really intimidated me haha so I appreciate posting your workaround. While still pingable, rejecting all those protocols from the br1 subnet essentially safegaurds our routers console from harm. Thank you again!

[@TheKauff]

@@DisasterousRDX @ChromeAftermath I'd also add in a line to block http traffic, not just HTTPS. It'd be the same command, just set dport to be http.

[@DisasterousRDX]

@@TheKauff Or it would be even better to just accept traffic to port 53 for DNS and 67 and 68 for DHCP. Then you can have any additional service on your router, you won’t have to block it in firewall.

thanks this helped me big time
