hi, all

I have download the 0.8.14 and latest rtpproxy(Download:
http://www.portaone.com/~sobomax/rtpproxy.tar )


when I start ser it said the follow errors:
 1(2747)  1(2747) DEBUG: init_mod_child (-1): nathelper
 1(2747) ERROR: send_rtpp_command: can't read reply from a RTP proxy

it seem rtpproxy don't reply to nathelper. Can someone know how to fix
it?
