Also, I tried portfwd and portfwd need transparent proxy in kernel. How do I enable this? Need your advice.

Transparent proxy using IPFW
Dear All, Is it possible to do like my requirement below? 1. Setup portfwd in my server listen on port 555 and forward all connection through this port to another server with same port or different port 2. All client which connected through this port, then remote server which landed to the end can see the client's IP. example: Client IP: 202.15.15.16 FreeBSD IP: 202.16.17.18 listen on port 555 Remote Server IP: 202.89.89.90 Client IP connect to 202.16.17.18 on port 555, and then FreeBSD forward it to 202.89.89.90 with same port or different port. Server with IP 202.89.89.90 can see Client's IP 202.15.15.16. I am using FreeBSD 7.2-stable.
