Regarding rtpproxy - if it makes your life easier, there is a very simple patch for the rtpproxy source which allows you to specify an advertised IP address on the command line this will be returned to OpenSips and inserted into SDP rather than the listening address. I used this last week for a server behind NAT and it worked perfectly.
If you want to mail me I'll happily send you a patched tarball of source.
