[Serusers] multiple ua behind same nat

[Marian Dumitru]

Hi Humberto,

Yes indeed, to avoid any mix up between the devices is recommended to 
use different SIP / RTP ports for each device.
If you use nathelper+rtpproxy, you don't need to set any port forwarding 
on the NAT box.
And just as a mention: if you have a call between two UACs from behind 
the same NAT, proxying the RTP stream is not required any more - let the 
media inside the private network.

Best regards,
Marian
