52Initial Setup

Joining a VPN Gateway to an Existing Cluster

After having installed the first VPN Gateway in a cluster, additional NVGs may be added to the same cluster by specifying the Management IP address (MIP) that identifies the cluster. When you are installing the VPN Gateway to join an existing cluster, less information is needed because the new VPN Gateway will fetch most of the configuration from the other NVG(s) in the cluster.

The following applies when joining a new VPN Gateway to an existing cluster:

•If the VPN Gateway you are about to join is installed on a different subnet than existing NVGs, this new device must be configured as a slave. Master NVGs cannot exist on different subnets.

•If the Access list consists of entries (for example, IP addresses for control of Telnet and SSH access), also add the cluster’s MIP, the existing VPN Gateway’s host IP address on Interface 1, and the host IP address you have in mind for the new NVG to the Access list. This must be done before joining the new VPN Gateway, otherwise the devices will not be able to communicate. Use the /cfg/sys/accesslist command. If the Access list is empty, this step is not required.

•If the VPN Gateway you are about to join has a different software version than existing NVGs, install the preferred software version on the new VPN Gateway before joining it (see “Reinstalling the Software” (page 70)) or upgrade the whole cluster to the same software version as the new VPN Gateway (see “Performing Minor/Major Release Upgrades” (page 74)). Use the /boot/software/cur command to check the currently installed software version.

Setting up a One-Armed Configuration

If the currently installed VPN Gateway(s) in the cluster are set up for a one-armed configuration you probably want the new VPN Gateway to be set up similarly.

When you log in after having started the VPN Gateway the first time, you will enter the Setup menu.
