Hello,

Im trying to use the the AVM FritzBox 7050 behind the m0n0wall.

But I'm not able to use the phone which is connected to the Fritzbox.
I can't make a phone call over VOIP (FritzBox) I think that
m0n0wall blocks the ports.

Who can tell me which ports I need to forward in m0n0wall
to use VOIP.
