Hi - Still plugging away at my Linux bridge/firewall and thinking through the consequences. In a normal firewall situation, the Internet is on one side, the internal LAN on the other. Duh! But now, with a Linux bridge in the middle, the whole thing becomes one big messy LAN. So we have a scenario that looks like this: Internal---User---Core-----Firewall---Internet---Internet router Servers switch switch (Bridged) switch (and default GW for internal servers) The scenario is a little more complex than I drew above because the internal side has more than one LAN segment participating in the bridge. I'm working on a way to simulate all this here - before going into production - but I have a big question; That firewall/bridge is no longer a router - it's a bridge. Well, a bridge that also does a bunch of stateful IP layer 3 filtering. So now, it will participate in a spanning tree setup with all those switches, on both sides of it - right? I'm guessing I want to turn off STP in this case. Am I on the right track?
