Dunca: I am not sure I understand your statemnet. SIP devices (UA) on the other side of the Internet behnid a NAT communicate to * on the public Internet. Then this Asterisk connects to other Asterisks (via IAX) that can be behind Firwalls (or NATS). am I understanding correctly? Uriel

I can't believe that... >Must be a solution... sip is very tricky to get working behind firewalls. sip clients work quite well with nat, just make sure nat=yes is in the sip profile in sip.conf my solution has always been to put an asterisk box behind the firewall and make all the sip clients connect to that, then IAX out of the firewall to the other machines. i spent a few days trying unsuccessfully to find a decent sip proxy that worked the way i wanted and decided that the asterisk solution was much better. duncan _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users
