[asterisk-users] Outgoing Calls Only -- Firewall Rules

[Nicholas Blasgen]

I'm trying to move my Asterisk deployments under a Virtual IP address and
now remember why I dislike this.  My primary Asterisk system is now behind a
firewall in private address space.  My question is what ports are needed to
be opened just for the purpose of placing outgoing calls.  I would have
assumed none, but I can't even get replies on registration from any of my 3
VoIP providers.  I tried defining the External IP and some other stuff, but
I assume it's fully an issue with the firewall.  Do I really need 5060 port
forwarded just to register with remote hosts?
