So I am doing a setup for my church. They have a modem for the private network (192.168.250.x) and a separate modem for the guest network (192.168.10.x). I already have our switch setup so that the guest network is being VLAN 2 tagged, and the private network is being VLAN 3 untagged. I have tested this VLAN setup to be working with my Unifi AP.

I have a couple Netgear R6250's on Kong Mod. I cannot figure out what settings to use on DD-WRT so that our private SSIDs (wl0 and wl1) are on VLAN 3, and the guest SSIDs (wl0.1 and wl1.1) are on VLAN 2. This is a much more advanced configuration of DD-WRT than I have ever had to do. Thanks for any help!

Create Bridges (br0 and br1)

On Setup->Networking assign the interfaces to the bridges.

Do I need to mess with Setup->Networking->VLAN Tagging at all? Or will they already be tagged when I separate the interfaces into their respected bridges?

The vlans have to be created before you can bridge them.

Use the CLI to configure VLANs.

Start by printing out the current variables.

Nvram show | grep vlan.*ports

This is the output I received

root@DD-WRT:~# nvram show | grep vlan.*ports
size: 37104 bytes (28432 left)
vlan2ports=4 5u
vlan1ports=3 2 1 0 5*

You have to use VLAN1 and VLAN3. VLAN2 is the WAN port.
Nvram set vlan3ports="3t 5"
Nvram set vlan1ports="3t 2 1 0 5*"
Nvram set vlan3hwname=et0
Nvram commit

Port 3 being the trunked port between the router and the switch.
