[OpenSIPS-Users] Rtpproxy behind the NAT

[Daniel Goepp]

We created a fix for this (see attached), this adds a -A parameter which you
can set to your public IP.  For example:

rtpproxy -A <public_ip> -l <private_ip> -s udp:localhost:12221 -L 8192 -m
25000 -M 34999 -F -d INFO LOG_LOCAL0

Using this, and a number of changes to the opensips config to advertise the
public address, rewrite contacts and sdps has our boxes running fine behind
NAT.
