hi, In a program, I have to implement a function. That is, (not a hacker's idea) A--------------R----------------B 1,A tries to make a tcp connection to B. 2,R is A's default router. 3,When R receive A's ip packet, it just changes the ip source address by the address of itself. Then R sends the packets. R pretends that it is him that wants to establish a tcp connection with B. 4,B receives the packets, and responds to R... The issue is B does response icmp packets(ping), but does not response tcp packets as if it regards them illegal packets and therefore discards them. Did I miss something? Any explanation is helpful. Thanks in advance. Board _________________________________________________________ Do You Yahoo!?
