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
