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!
Moacir

Thanks All,
Yes, please if you've an example using nathelper without rtp proxy let us
know.
now more than ten days I am trying to get kamailio up & running to bypass
NAT & firewall blocking but I couldn't.
After some research I might create a VPN.
so please if you have any working example for NAT and Firewall let us know.
Regards,
Amr

Hello,
rtpproxy could bring some delays, as another hop in rtp path. But usually
is
not noticeable, unless rtpproxy is on a slow network.
Look at the traffic coming to rtpproxy and going out (with wireshark or
similar tool) to be sure you have delays from rtpproxy.
Cheers,
Daniel
