Hi
U are not getting the problem.
When A sends echo request packet to B, B should send a
reply packet back to A. But this is not what's
happening. I have put a sniffer on B. B is receiving
the packet as such with source as A and destination B.
SO what u r saying that i am chaanging the ip b4
forwarding the packet is not happening.
The problem is :B is sending the ICMP packet with Source:B Destination :Gateway's Interface to B
The ICMP packet type is Destination unreachable
and it's code is Protocol Unreachable.
The same thing also happens the other way round i.e
when B pings to A. So i assume problem is somewhere in
the code..Can it be some port problem or what????
