    Ingress filtering for multihomed routers will accept the packet if there is a route back to its source address from any interface on the router. For this type of filtering, the router may also maintain an adjacency table, also organized for fast lookup, that keeps track of the router interface addresses that are on all directly connected ...

    Port triggering is a configuration option on a NAT-enabled router that controls communication between internal and external host machines in an IP network. It is similar to port forwarding in that it enables incoming traffic to be forwarded to a specific internal host machine, although the forwarded port is not open permanently and the target internal host machine is chosen dynamically.

  7. Control plane - Wikipedia

    When an interface has an address configured in a subnet, such as 192.0.2.1 in the 192.0.2.0/24 (i.e., subnet mask 255.255.255.0) subnet, and that interface is considered "up" by the router, the router thus has a directly connected route to 192.0.2.0/24. If a routing protocol offered another router's route to that same subnet, the routing table ...
