[Users] outgoing proxy through VPN ?

[gary ng]

Hi,

I am trying to setup openser as an outgoing proxy
through VPN with the following setup:

172.16.1.1 - VPN endpoint and also the machine running
openser
172.16.1.2 - remote NAT router at Network A(another
VPN endpoint)
192.168.1.x - sjphone client behind NAT router(Network
A)

I can register the client through 172.16.1.1 fine but
dialing out to other SIP address like
613 at fwd.pulver.com never go through.

If I register through the public address of the
machine running openser, I can make the dialing fine
and can sort of having a two way communication, though
it drops after 5 seconds for unknown reason.

I am wondering if anyone know if the first
scenario(register through VPN) is possible.

Also, how to trace why the communication drops for the
normal registration method.

thanks for any help in advance.

regards,

gary
