Hello, I have quite a particular routing / masquerading problem I explain in an early message to this list. My problem may be solved if there is a way to modify packet destination address AFTER the routing has taken place. I want the routing mechanism to choose the outgoing interface and after that change the address of the destination machine - a bizzare situation, but read the message I posted few hours earlier. Is really a way there to do that with iptables, or a similar tool / approach? George.
