Hello!

I have a question regarding the VLAN config on the Backfire OpenWRT (WRT54GL).

Current Situation: I have a ZyXEL USG 20w Firewall running at home. The WLAN is divided into my private WLAN and into a Guest WLAN. Both WLANs are running in a seperate Subnet and are also seperated from the LAN. The USG is supporting VLAN.

I have also an old WRT54GL here, flashed with Backfire. Is the following appoach possible.

*) Can I configue on the WRT54GL on one of the LAN (or the WAN Port) a network, supporting to receive and transmit 3 different VLANs to the USG?
*) One VLAN should be distributed to the remaining free LAN ports, supporting the LAN from the USG.
*) One VLAN should be used for the private WLAN
*) One VLAN should be used for the Guest VLAN

No firewall or dhcp is needed, both should be done by the USG.

Best Regards,
Johannes
