how can i route packets to differnet destinations depending on their source

I have an issue with re-routing a frame relay service. I need do make data go through one serial subinterface for one client and through another for another client. If data is not destined for either client then it should leave through the default ethernet interface. What is the best way to achieve this - I am thinking towards using a route map with NAT pool.

Re: how can i route packets to differnet destinations depending

Unless you have a real need to change the source and destination IP on the packet, the tool you want is called "policy routing". If you can match the traffic source with an ACL, you can policy route it in a different manner than you would normally route it (you can send it to a different interface, for instance). As CCO has copious documentation on policy routing, I'll ask you to search for policy routing documentation rather than pick a URL to post here.
