Hi Nick, Thanks for that Nick. I was making the problem much worse that it needed to be. My interpretation of the IP stack and routing was that the souce ip/subnet and the destination ip/subnet were compared and the routing tables only used if they didn't match - hence my attempts to alias and then forward. However, as both Linux and Win9x boxes still use the route tables if the subnets match, a simple route rule did the trick.
