So, in effect, you're changing the behaviour of your (level 3) port to a level 2 port, i.e., a switch, and add some filtering features to it, or am I missing something? In that case, you might get away by configuring the two pairs of ports as ethernet bridge ports, and only assign IP-addresses to the two outer interfaces as in the diagram above. Not sure whether all shaping and firewalling tricks will work in that case though. Anyone got a comment on that? Regards, -- Q_.
