older versions of RHEL had a lokkit text menu based util for setting
basic firewall ports. I dunno but it may still be available in current
versions. all it actually does is edit that sysconfig/iptables file
and restart the iptables service that tony mentions, same as the GUI
program does.
also, you could make a backup of that file on a GUI system, add a port,
then diff the backup and the current iptables file to see exactly what
the GUI does
