Hi everyone!
I am currently trying out the examples from the Getting Started manual
version 04a from Onsip.org. The reference design there shows that SER
itself is nated. My question is how will a UA from the public internet
or somewhere outside the SER's nat register with the SIP server? Will
I put the SER's nat public ip as the sip proxy and do I have to set
some kind of port forwarding on the SER's nat? Also, doesn't
mediaproxy have to listen on a public ip? The document is actually a
good tutorial and just need additional clarifications for issues like
nat.
Thanks Guys!

That's correct. However, you are better off with SER on a public IP if you
primarily serve external clients. If SER is NATed, you need to make sure
that the public IP of SER is advertised (_port and _ip) and that the public
IP is used in record_route_preset(). Of course, you also need to do static
mapping on the NAT in front of SER to forward port 5060 to the inside
address. I recently posted a more thorough explanation of this.

Yes.

Yes. This is described in the document
and thoroughly documented in
mediaproxy's README files.

Hi Greger,
Thanks for helping me out. I followed your advises and I have now a
working SER and Asterisk PSTN GW on public.Its a lot simpler to
implement it that way =D.
Thanks again,
_Jeff
