I'd like to have two VLANs on my WRT54 v2 running tomato 1.19 (can upgrade if needed). One VLAN would be for ports 1-3 and WLAN that should function like it does right now. That is DHCP 192.168.1.x/24 which has access to the internet. The second VLAN should apply to port 4 only and would give it an IP of 192.168.2.x/24, but that would limit it only to the LAN, I don't need internet on this port. I've read some tutorials for DD WRT, but were unable to follow them. I know the GUI of Tomato doesn't support VLANs, but would appreciate a step-by-step how this could be done with startup scripts or any other method.
