Please help! My setup is: [A]-----[fxp0:D:fxp1]-----[C] fxp2 ---- | | [B] D is the box that runs ipfw + bridging. My rule is very simple: 100 fwd B log all from A to C last rule allow from any to any Ideally , it should redirect any packets from A to C and emit them out on interface fxp2 (linked to B). And those packets are to be dropped dead on B. What happened is that logging messages indicate that rule 100 were envoked but with no effect. One can still ping from A to C. IPFW with no bridging (ie. machine B acting as a router) works fine. Bridging alone works fine. But when combining ipfw + bridging, the fwd command doesn't work. Any one has the same problem before? Also, I assume when doing bridging, I don't need to config the routing table in machine B. Is this correct? Any commets highly appreciated.
