[Serusers] How to send PSTN CALLs to a NATED PSTN GW?

[Alberto Cruz]

Hi guys maybe this have been asked before.

I have the following:
* I have an ADSL Internet access with a public dynamic IP.
* I have a broadband router in order to share the Internet access using NAT.
* I have a VoIP GW that supports register connected behind the NAT.

When the GW registers itself SER knows its source IP and UDP port.

Does anybody knows how to forward the PSTN calls to the GW when it is 
behind a NAT?
