Ok, question

You mean your firewall? is this a windows, linux, or router firewall? If you have a router, you don't need Windows or Linux firewall, unless you have a DMZ server.
heres some ports;
3306/udp 5999/udp 9000/udp 7000 - 7005/udp 3306/tcp 5999/tcp 7000 - 7005/tcp
You don't need to clear ports on your router if you play in your LAN only

If you use static zones, then you have to open more of the 7000 ish zones
