ip traffic redirection.

[fred at bsdhost.net]

Hello gang...

This is maybe the wrong list for this question but anyway...
For a proof of concept I need to setup a gateway to divert certain kind 
of ip traffic to a special program who do some counting and 
modification on these packets and then re-inject them back. This has to 
be a gateway and not a router.

Does someone know if there is a package un the FreeBSD ports who can 
help me do that? Can I do that using ipfw and in that case can someone 
send me a pointer to some docs or examples ?

Thanks a lot.
Fred
