I'm not sure if running rtpproxy behind NAT is a good idea, but there is
a patch on internet for adding "advertised address" setting to rtpproxy:
I've used it ok for some experiment.

Also I can suggest looking at Sipwise sip:provider, which supports
advertised_address setting for both signaling and RTP out of the box.
If you are looking for paid support for setting up a RTP proxy behind a
NAT, please contact me off list. Good luck.
