As long as you only forwarded the particular ports and only the UDP layer, you should be relatively fine. If you are at home chances are you just have a router which works to an extent. If you have a datacenter server chances are you have to manually put in iptables (port restrictions).
Keep in mind that EQEmu uses TCP to handle traffic between login<->world<->zone.
The EverQuest Client and EQEmu use UDP against each other so thats the only protocol that should be open to everyone.
