[Users] openser + nathelper + rtpproxy w/ ekiga

I'm trying to use openser's (1.1.1) default nathelper.cfg to connect two 
ekiga clients. One is behind a NAT. Both can contact each other, but the 
media streams (neither video nor audio) don't seem to be setup for some 
reason. rtpproxy registers that it should setup the connection, but it 
doesn't seem to take off past that.

here's an ngrep dump of the NAT'd client calling the other, and could 
appreciate some wisdom on what I need to fix and what the problem is. 
thanks.
