system-config-firewall provides a fairly simple way to set up port  
forwarding. But, it's a take-it or leave-it proposition. system-config- 
firewall will either take over all of your iptables configuration, or you  
have to roll your own on everything; however system-config-firewall does  
allow you to specify an external file with fixed iptables rules that gets  
incorporated into system-config-firewall-generated ones. So, you might be  
able to migrate to system-config-firewall, even if you have some custom  
rules installed.

Then, it's a matter of figuring out which ports need to be forwarded. Your  
problem may not necessarily be a firewall rule config issue, but knowing  
which ports you need to forward.
