Actually, I assume the above (2 x IAX devices behind a single NAT router) would work perfectly without any special configuration EXCEPT in the (perhaps most common case) where both IAX devices are talking to the same IAX server. Wherever I have used the number 2, it could just as easily be any other positive integer. PS, The reason I say that is generally when we refer to NAT we also refer to PAT (Port Address Translation <?>), so we end up with a table like: 192.168.0.44:5436 -> 202.10.10.23:5436 -> 203.45.23.10:4569 192.168.0.45:5487 -> 202.10.10.23:5487 -> 203.55.32.10:4569 So, when the router sees a packet from 203.55.32.10:4569 it knows where to forward it to (192.158.0.45). Actually, extrapolating: 192.168.0.44:5436 -> 202.10.10.23:5436 -> 203.45.23.10:4569 192.168.0.45:5487 -> 202.10.10.23:5487 -> 203.45.23.10:4569 We still are ok, because the router will still appropriately translate the incoming packets (looking at the destination as being 202.10.10.23:5487) as being for 192.168.0.45:5487 So, although I haven't tried it, I'm assuming it should work without any problem. The only thing tickling the back of my mind is that the outbound port on IAX packets is always 4569, but one of these is going to be translated by the PAT on the router to something else... I'm not sure if this breaks anything.
