Topic: How can I do port mapping?

[Craig]

I need to map some incoming ports so that I can use telecom software from within my private network. How can I do this?

Craig, I feel your pain, i too have been having trouble figuring out how to get port mapping to work.  You'll need to use ipchains, i haven't had time or energy to figure that out, but there are how-to pages all over the web, also try the 'man' pages (man ipchains).

The easiest way to do TCP port mapping is actually not to use ipchains at all, but to use a small connecting program such as "socket" or "netcat",
and configure inetd (or rlinetd in e-smith 4.0) to start:

socket machine port

whenever someone connects to the port of interest on your server.
