Topic: Opening specific ports??

[Mark Powers]

What file or method would I use to open and close ports to allow connections to machines inside the firewall?  I have need of this and opening a port will be much easier than switching my network connections (bypassing the firewall) all the time.

BTW Kudos the e-smith team!! From junk laying around my computer room to fully functioning firewall in 90 minutes, including 20 minutes to troubleshoot a power up problem!!

Hi Mark,

If you only have a limited number of machines and ports to map,
and none of the ports is needed on more than one machine, and
none of the ports is in use by the server, then I would start
a small socket connector program like "nc" or "socket" from
inetd on the server. You will need to edit /etc/e-smith/templates/etc/inetd.conf to set that up.

If the ports aren't unique if will be harder to do. If you have
a routable network you would fiddle with the ipchains setup.
