Dear List, I am trying to figure out if is is possible to route packets through an OpenBSD firewall on the basis of the packet source.
The situation is that I have two ISPs hooked up to a firewall and would like to route traffic to these ISPs on the basis of which NAT client (IP or mask) the traffic is coming from. Is this possible? What mechanisms (pf... etc)? I am also hoping to work ifstated or something like it into the mess so that if the normal route for a client fails the traffic will go to the secondary connection. Is this reasonable? Thanks, Dhu
