Hi, I want to simulate a scenario with dumbbell topology (2 end nodes(say n0, n1) and 2 routers(r0, r1)). One of the router (say r1) will act as a packet spoofer. A FullTcp connection (n0-n1) will be set up between two end nodes and r1 will check particular ACK packets and will create duplicate copies of it (to be sent to source). Is it possible to simulate such scenario in ns2?? Any help is appreciated.
Thanks, Ashish Bhandari
