When I installed RH 7.1 I did not understand that the "firewall" would close so many ports. I was curious if I can open certain ports e.x. 7777.

At least my RH used ipchains as firewall. But it also had iptables enabled. I would suggest to check which one is handling firewall settings. You can see the ipchains you have with command "ipchains -L".
Then you need to modify the ipchains/iptables to open the ports for incoming/outgoing traffic as is needed by whatever program you're using. If you have ipchains as firewall i suggest you try out Securing and Optimizing Linux: RedHat Edition (http://www.linuxdoc.org/links/p_books.html#securing_linux). It helped me to get my ipchains to somekind of order.
If you're firewall works with iptables, then i can't help as i haven't tried them yet. I've been trying to do so, but haven't had the time.
