[Asterisk-Users] RE: Multiple IAX clients behind a firewall

[Adrian Carter]

Thanks all for advice... I have IAX clients configured pretty standard, 
and they work fine connecting to the asterisk server if coming via the 
itnernet.. but the moment I have more than one attempted client from a 
remote office that gets NAT'ed into the 'main' network so to speak it 
doesnt work. I only see one client connect and "iax2 show peers" 
reflects only one client from that IP and its connected on 4569. 
Subsequent clients attempting to connect behind the NAT router get 
'connection timedout' when trying to register. If I unregister the first 
client, a new one can register, but the same symptoms persist (the guy I 
unregistered can't re-register again ...)

Its a Dlink DI714P+ router in a completly vanilla out-of-the-box setup - 
so if IAX 'just works' - what am I missing?? :)
