I have an Asterisk server with one SIP trunk to a SIP provider. As my

has some trouble with my NAT).


You could try iptables with ip_conntrack_sip ip_nat_sip.

If they are loaded and you accept calls from your sip provider on port
5060 iptables inspects the sip/sdp and traffic from the endpoints are
considered RELATED.

I've some research/testing to do myself on this topic (it's on my always
growing todo-list of doom.. :-)

Maybe you should check it out?


Thanks Johan. It will have to go on my todo-list of doom as well :-) - 
will eventually get around to investigating those two iptables options. 
Sounds promising.

I know for sure how to do it in asterisk, but I don't know how to do it
using elastix interface. Maybe you can have more luck asking to some
elastix related mailing list.
