It was self-resolving, but ...

We were able to connect if you turn ON the tunnel, but the tunnel is needed? In an environment in which there is no NAT or FW on the server side?

Server has been set directly globalIp address, there is no NAT or FW.

It was a tendency that regist may become unstable if you turn ON the tunnel, where he was to OFF about a week.

There is no problem even now OFF
