Hi swa,

Since you asked for program, NS2 is a famous free tool used academically for quickly setting up networks of various configurations (The Network Simulator - ns-2). It is only available on linux as far as i know.

Else you can write a client and a router both of which run on the same machine using loopback address do the same job.

Hi swa,

I didn't know much about opnet. But i googled a little. They are a public listed company in the same domain but i don't think any of their tools come for free.
