Hello Moacir,
Yes, my Kamailio server is on virtual machine & its connected direct to the internet. Regards, Amr From: sr-users-boun...@lists.sip-router.org [mailto:sr-users-boun...@lists.sip-router.org] On Behalf Of Moacir Ferreira Sent: Tuesday, March 19, 2013 10:00 PM To: Kamailio Mail List; mico...@gmail.com Subject: Re: [SR-Users] NAT & Firewall Issues NATed solutions with no RTP proxies will depend on the client side, not on the server side like in Kamailio. Key things to notice: 1 - Private IPs (RFC-1918) will always be proxied if you don't change the basic template config; 2 - Dual NIC servers require a little bit more knowleadge on Kamailio before you can get it to work properly; 3 - Although you can use some tricky configurations, Kamailio is not a SBC like Asterisk/Freeswitch; Having said that, RTPproxy is just good. I mean, it is really good! If it is not working, then you probably have another problem. So the questions are: Are you running your system on virtual machines? What is your topology? How many NICs do you have? Your Kamailio server is connected direct to the Internet or behind a firewall? All the above questions can strongly affect the quality of your calls. Cheers!

After some research I might create a VPN. so please if you have any working example for NAT and Firewall let us know.
