[Users] How to gaurd PSTN gateway with openser + NAT

[Lokesh Kumar]

Hello Friends,

I installed openser, it is working fine. sipsak-0.9.0 is also working fine,
previously i was using 0.9.2 version of sipsak that is having problem.

Now I want to ask you 2 important things.

1>> Forget Asterisk for sometime, I am having a openser with one public IP
and one private IP, and I am having one voip gateway which is connected to
E1 PRI, and voip gateway is also having private IP. So, my question is can I
forward all the calls coming on public IP of openser to voip gateway via
private IP's of openser and voip gateway.After that voip gateway will
forward the call to E1 PRI.
SER Admin guide mentioned about how to gaurd your PSTN gateway with SER, but
the documentation is not suffciente there. So, can you please suggest in
this scenario, how do i can configure request routing in openser, like
pstn.cfg file.

2>> How do I have to register SIP phone on openser. Where the sip phones are
behind the NAT, but NAT device supports STUN and UPnP. Do I need to setup
seperate STUN server or I can run this service on openser server.

Please help.
Regards
Lokesh
