[Asterisk-Users] RE: Help needed with IAX behind NAT

[Darren McIntosh]

<snip>
In this configuration I had to forward the iax port on both NAT boxes to the
* box.
192.168.0.100 -NAT1-> publicIP <-> publicIP -> NAT2 192.168.0.100

It wasn't sufficient to register from one * box to the other to get audio
working because the source port was different. * was version 0.4.0 and the
NAT box was netbsd/ipfilter 3.4.27 in this case. If things haven't changed
too much, might be your problem, can your firewall admin forward iax ports
to your gnophone?

cheers,
