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.

Log in as the Administrator user when the login prompt appears and check the operational status again.

Console Connection

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 up.

If the operational status is indicated as up, 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 up.

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.
