Hello all, Does anyone know of a methodology to build a route based on the inbound and outbound interfaces as opposed to ip addresses? We are essentially trying to forward packets from one interface to another without looking at the ip address. Bridging (brctl, br2684ctl) will not work in this case as the interfaces use different layer 2 encapsulation (e.g., atm0<=>eth0, or ppp0<=>eth0). We could build a rule to match the incoming interface, then point to a routing table with a default route set to the outbound interface. The problem, with this approach is the limit of 255 routing tables in iproute2. Presumably, it would consume 2 routing tables for each "connection" (one forward, one reverse). We need more than 126 "connections" per box. Some commercial routers allow policy routing using only the interfaces with ACL's, but it's not clear how this could be implemented in linux. We use debian (2.4 kernel) distro with iproute2, iptables, etc. Any suggestions would be most welcome.
