Red Hat 7.1 Firewall Configuration

I just installed Redhat 7.1. I also installed the new “out of the box” firewall during the installation, choosing medium as my setting.

I wish to now open up additional ports (23, 25 & 110) and I cannot figure out how to open them and have notbeen able to find any documentation regarding this new firewall.

Linuxconf is not installed on my system. I would perfer to be able to modify the settings from the command line.
