Is this possible in=20 FreeBSD with ipfw?. 2.- I am a client A connecting to public ip 1.1.1.1 (for example) of = host B. I want this packets at B to be redirected to host C but changing the source address of A from that packets with the ip = address of B. Later when B receives back the answer of C that packets from the answer to be redirected to A changing B = destination ip address to A destination ip address. So when telnetting from client A to host B for example to port 5000, really, to be = telnetting host C port 5000 for example and work this telnet properly = from A. The most important question is number two. Could you help me please?. Best regards.=
