Hi serusers,
after reading lots of docs and mailing lists I still have some doubts about
nathelper+rtpproxy and the error message I usually get from it is
rtpproxy: can't bind to the IPv4 port 35000: Cannot assign requested address
what is the correct way to start rtpproxy? do I have to provide nat and public
ip?
In the following situation: machine behind nat with private IP, running ser
and reachable from the outside via port forwarding on router's public ip
(forwarding port 5060 for ser and ports 35000-.... for rtpproxy range, both
udp/tcp), can I use rtpproxy? how should i start it?
(in the above situation ser registration from the outside works!)
thanks in advance

I think maybe this can help you:

At the bottom of the post there is a link to an rtpproxy patch for
behind-NAT operation.

Thanks a lot Greger, the patch works very fine and solved my problems!
For anyone who was not lurking the mailinglist in november the patch is not
easy to retrieve as it was posted as attachment and so snipped from the web
archives. So I re-post it here in mail text.
