I get your point, I really do. I'm just trying to figure out a way *not* to have to specify each and every subnet behind a firewall interface as these will change dynamically over time and be learned via OSPF. That's why I was looking for a way to express filtering rules for forwarded traffic based on a combination of ingress and egress interfaces for cases where this is considered enough (i.e. specific subnets don't have to be expressed in the rule).
