Code:
3306/udp 5999/udp 9000/udp 7000:7004/udp 3306/tcp 5999/tcp 7000:7004/tcp
That's what I have cleared off my Linux firewall , 5999 is the mini-login port and 7000-7004 are the default Zone-Launcher ports. For static I add in the ports that follow (example 10 additional static zones would be 7000:7015.
The zone launcher ports may be different to you, but over here it's what my emulator defaults to (if I don't change anything).
