Hello,
I have the same troubles with ser+rtpproxy.
I think of you'll waste time because of rtpproxy+ser
documention is bad.
I looked at www.onsip.org in order to find help about
NAT without success but you can waste time to send
help to serusers mailing list.
We can read some nat troubles in mailing list every
week.
I do hope you'll find help.
Regards
Harry
