[Serusers] rtpproxy

[Toygun Mavinil]

Hi there,
I try to use ser 0.9.6 on fc4 with mysql rtpproxy because of nat
No errors starting ser
On local, no problen betweeb ip phones and gateways but one way voice
problen on sjphone
On wan, always voice goes one way, caller can nor hear but callee can hear
and can not talk
FC4 gets wan ip directly, all firewalls are off.

I tried with mediaproxy module, nothing changed,
Here is ser.cfg (from configs.GettingStarted);
