Could you explaint your scenario better?
The server is in a private network?
The cliets are in different private networks?

Thanks for the advice Flavio.
Currently I am actually pretty close with my NAT'ed OpenSIPS and
NAT'ed clients. I am assuming this is because I have a simple NAT
scenario with full-cone NATs.
I get as far as making a call, but when I pick-up the call only one
side gets RTP through. I traced the problem to the fact that a local
address is being put in the "Record Route" section of an ACK response.
I would like to try to get this more controllable scenario working
first before I launch into new complexity with RTP proxies etc. I
think that I just need to know how to get the fix_nat_sip() and
fix_nat_contact() to work. Any pointers with that?
Regards
Mark

Hi Mark,
There is no simple way to traverse NAT. Unless all your routers use a
non symmetric NAT, you will have to use rtpproxy or mediaproxy (you
can check this with a stun client). OpenSIPS behind NAT make things
even more complicated. So I suggest that you follow an example with
rtpproxy or media proxy and also use the OpenSIPS in a valid IP
address. The setup you are trying to do with OpenSIPS behind NAT is
possible, but it is even more complex.

Hi,
I have a very simple setup for a closed network of users (all NAT'ed) with
one OpenSIPS server (also NAT'ed).
I have managed to solve my first problem with registration by following
previous posts and using fix_nat_register(), but I am still having
problems
with NAT issues during a call. I know that I probably need to use
fix_nat_contact() and fix_nat_sip() but I can't figure out how to use
these
properly through the documentation.
I have tried to search for examples of opensips.cfg that suit my scenario
but all the ones I found are complicated with proxies etc. Can someone
point
me to simple example of opensips.cfg that takes care of NAT?
Regards
Mark Currie
