VLAN ID issue?

Hi,

I'm running Tomato Shibby (build5x-136-EN-MultiWAN / tomato-E3000USB-NVRAM60K-1.28.RT-MIPSR2-136-VPN.zip) on a Linksys E3000 and I got issue with setting up VLAN.

So I want to set up a VLAN to port 3 of the router. As I'm new to Linux and CLI, the best way is to do it on the UI. Anyway what I did was:
- Clean Router NVRAM
- Go to Basic-Network, change IP address of br0 to 192.168.17.1 [quite not relevant here, but anyway...]
- Create another bridge br1, IP address is 191.168.171.1,...

VLAN ID issue?
