Juan,

The solution is simple: DONT DISCONNECT YOUR GATEWAY.
And if you do, you should be able to restart your VEE-model
without problem. However, an old session on your gateway may
block normal operation. Log in to your gateway via
telnet, and check for such blocking sessions. You can easily
reboot/reset your gateway if such sessions exist.

Kind regards,

Frank
