IP Forwarding on Redhat to AIX Network - SIMPLE QUESTION!
 

Hi! I'm looking for help with Redhat Linux 7.2.

I have an internal network with four machines, three AIX machines and 1 Linux. Linux is attached to the real world and is using IP Masq to provide connectivity to the AIX machines.

What I'd like to do is have the Linux machine pass telnet requests to external address on port 3243 to one of the internal machines on port 22. If I have to, I can set the internal service to port 3243 as well...

I just don't know how to get IP forwarding to work on Redhat 7.2 and then be able to specifically redirect incoming external requests to internal machines/services!

Any help would be greatly appreciated!
