A Telnet connection offers the convenience of accessing the NVG cluster from any workstation connected to the network. Telnet access provides the same options for user access and administrator access as those available through the console port.

To configure the NVG cluster for Telnet access, you need to have a device with Telnet client software located on the same network as the VPN Gateway(s). The VPN Gateway must have an IP address and a Management IP address. If you have already performed the initial setup by selecting new or join in the Setup menu, the assignment of IP addresses is complete.

When making configuration changes to a cluster of NVGs through Telnet, it is recommended that you connect to the IP address of the MIP. However, if you want to halt or reboot a particular VPN Gateway in a cluster, or reset all configuration to the factory default settings, you must connect to the IP address of the particular VPN Gateway. This also applies when using an SSH connection instead of a Telnet connection. To view the IP addresses of all VPN Gateways in a cluster, use the /info/isdlist command.

Enabling and Restricting Telnet Access

Telnet access to the NVG cluster is disabled by default, for security reasons. However, depending on the severity of your security policy, you may want to enable Telnet access. You may also restrict Telnet access to one or more specific machines.

For more information about how to enable Telnet access, see the telnet command in the "Administrative Applications Configuration" section under Configuration Menu>System Configuration in the Command Reference.

For more information about how to restrict Telnet access to one or more specific machines, see the add command in the "System Access Configuration " section in the same chapter.

Running Telnet

Once the IP parameters on the VPN Gateway are configured and Telnet access is enabled, you can access the CLI using a Telnet connection. To establish a Telnet connection with the VPN Gateway, run the Telnet program on your workstation and issue the Telnet command, followed by the VPN Gateway ’s IP address.
