[Asterisk-Users] Almost there--Remote connection

[Ferguson, Michael]

Thanks. The server is NAT'd.
So, Am I to conclude that it is not going to work and I should abandon
it?

Of course not.

Running a SIP server behind a Firewall does not exactly make things
straightforward.

Is your server is only behind a firewall or is it also behind a NAT?

If it is behind NAT you should know that that SIP/NAT traversal
workarounds are for clients behind NAT connecting to servers on public
IPs, not for clients on public IPs connecting to servers behind NAT.
