[Serusers] ser+nathelper+rtpproxy / can't read reply from a RTP proxy

[Akira OKUBO]

Hi,

I have just installed ser this week.
It's very cool and happy to find FreeBSD port of it.

Anyway,
I have rtp proxy connection problem of ser+nathelper+rtpproxy system.
To refer console log, it seems no communication between ser and rtpproxy.

Does anyone know how to fix it?

Here is my environmnet:

OS         : FreeBSD 4.10-RELEASE-p2
ser version: ser 0.8.14-2 (i386/freebsd)
    get stable version from CVS, since port version is still 0.8.12...
nathelper  : get from CVS 14-Oct-2004

I run ser and rtpporoxy as root user to avoid permission issue.
and /var/run looks no problem.
