asterisk users - Nov 2005 - IAX and Firewall

Do I have to have IAX2 port (udp 4569) open when receiving calls from a
registered server.
My asterisk shows that it is registered with teliax server but the calls
to my asterisk are being dropped?

Unless your firewall is integrated with *, which I sincerely doubt, yes you
will need to open the right port on your firewall.  Make sure that you set
up your NAT and/or pinhole [if applicable] to point to your * box.

I don't believe so. By registering with the remote server, 
you are giving them the NAT port to get back into your 
server with. All communications will take place on that 
port.

THe only time you would need to open up the firewall and 
direct the port to your server would be if you have a user 
on the outside that is registering back into your Asterisk 
box.

I know someone will correct me if I am wrong, but I 
believe that is the way it works. You have to forward 
ports for SIP because of the way the RTP stream is setup.
