Perhaps I am making it harder than it is. But I > only have two NICs, and the routers sit on 2.2.2.0/27. Sure you could. Consider this: add 1000 fwd 2.2.2.2 ip from 10.10.10.128/25 to any out recv ed0 xmit de0 add 2000 divert natd ip from any to any via de0 This does divertion for all of your addresses (probably what you want) and just fools with the next hop address of the 1 source subnet. This is assuming that your default gateway is 2.2.2.1. Nick Rogness <nick@rogness.net> - Keep on Routing in a Free World... "FreeBSD: The Power to Serve!"
