[mythtv-users] Disable firewall in mythbuntu???

[Stephen Sassman]

This is one thing that has troubled me ever since I switched to
mythbuntu. I cannot change the firewall settings to open a port or
disable the firewall. I have tried using shorewall, firestarter, gufw,
and iptables. No matter what I change, the same ports seem to be open
always according to nmap (20, 80, 139, 445, 1080, 3306, 6543, and 6547).
So how do you change firewall rules with mythbuntu???
