Do you mean that any calls to these ports should be forwarded to the 192.168.2.12 box? If so then i am sorry but you are out of luck as this cannot be done. IP forwarding is used to forward from one ip to another. Sorry that I couldn;t be of more help,

Regards,

Jason

It can be done. You want a package called ipautofw that will redirect ports on a firewall (masquerading machine) to other machines behind the firewall.

Pick it up from ftp://ftp.netis.com/pub/members/rlynch/

The intention is to provide a generic solution to allow 'difficult' protocols to be successfully masqueraded, but you can also use it to bridge a firewall for specific ports.

I have heard that ipautofw is buggy at best. Is it stable under 2.0.3x

I haven't used it myself, but I've heard from people who have it working satifactorily. There's another similar package, called, I believe, redir, which is specifically aimed at what you want to do.
