I'm using a FritzBox 5012 behind m0n0wall. It is working very well for
outgoing calls but incoming calls from other VoIP people are not really
working. Especially for incoming calls from other people with "schlund
und partner" (also 1und1 and GMX) phone numbers.

I made the following incoming ports with incoming NAT rules:

Firewall rules:

Incoming UDP Source-IP any Port 3478      Dest-IP any Port any
Incoming UDP Source-IP any Port 3478      Dest-IP any Port 5060
Incoming UDP Source-IP any Port 5060      Dest-IP any Port any
Incoming UDP Source-IP any Port 3478      Dest-IP any Port 7078-7085
Incoming UDP Source-IP any Port 7078-7085 Dest-IP any Port any

NAT rules:

WAN UDP Port 3478      NAT IP <fritzbox> Port 3478
WAN UDP Port 5060      NAT IP <fritzbox> Port 5060
WAN UDP Port 7078-7085 NAT IP <fritzbox> Port 7078-7085

I have tracked the error with ethereal and tcpdump and I think the
biggest problem with this is, that some incoming call are fragmented and
m0n0wall doesn't do this very well with NAT.

Perhaps someone can help us...

Thanks in advance,
Matthias
