I'm trying to get my LAN port to act as a trunking port and use vlans instead of just a straight up IP. Problem is, when I delete the LAN interface I lose access to the web interface because it's listening on there, and not the vlans. How do I tell it to listen on one or more vlans? I already have vlans setup on my switch and on the firewall, it's just that for the routing to work properly between vlans the WAN interface has to be deleted, apparently. But when I do that, it trashes the firewall.
