The NVG Stops Responding

Telnet or SSH Connection to the Management IP Address

When you are connected to a cluster of VPN Gateways through a Telnet
or SSH connection to the Management IP address, your connection to the
cluster can be maintained as long as at least one master VPN Gateway in
the cluster is up and running. However, if the particular VPN Gateway that
currently is in control of the Management IP stops responding while you
are connected, you need to close down your Telnet or SSH connection
and reconnect to the Management IP address.

After doing so, you can view the operational status of all VPN Gateways in
the cluster by typing the command

/info/isdlist

. If you find that one

of the NVG ’s operational status is indicated as

down

, you should reboot

that machine. On the VPN Gateway, press the Power button on the back
panel to turn the machine off, wait until the fan comes to a standstill, and
then press the Power button again to turn the machine on.

If you are connected to a particular VPN Gateway through a console
connection, and that NVG stops responding, you should first try pressing
the key combination CTRL+ ^ and press ENTER. This will take you
back to the login prompt. Log in as the Administrator user and check
the operational status of the VPN Gateway. Type the command

/info/isdlist

and see if the operational status is indicated as

If the operational status is indicated as

, the VPN Gateway should

continue to process SSL traffic without the need of a reboot.

If the operational status of the VPN Gateway is indicated as down, try
rebooting the device by typing the command

/boot/reboot

. You will be

asked to confirm your action before the actual reboot is performed. Log in
as the Administrator user and check if the operational status of the VPN
Gateway is now

If the operational status of the VPN Gateway still is

down

, reboot the

machine. On the device, press the Power button on the back panel to turn
the machine off, wait until the fan comes to a standstill, and then press the
Power button again to turn the machine on. Log in as the Administrator
user when the login prompt appears.
