Hi, Giorgio. So far so good. I have twinkle running on my laptop (the
VPN client), a Snom 320 and a Snom 360 on the internal network routing
through my laptop. I haven't done much more than register and execute a
very basic dialplan but it is all working so far.
I hit a couple of small bumps but nothing to do with *. I had forgotten
to tell my DNS to accept requests from the test network. One of the
phones somehow decided the data center firewall was an outbound SIP
proxy. Once I removed that setting, it all worked just fine.
I am using native addresses across the VPN; there is no NAT.
I've not yet had sustained conversations. I'll be doing that in a while
hopefully - John
