I havent done an exhaustive search on this but havent found the post I am looking for...

It seems when I play with my Asterisk based box here that there are two different servers involved on Voipo's end.

And- if I set it up one way I get one incoming server in my firewall states. But another if I set it up "Nat + Dynamic IP... Picture at "Topology"

I think my outgoing calls dont work using their product because this particular product does not have settings to deal with this architecture...
Am I on the right track here...
