Operation Manual

In order to set up a tunnel you must configure the following:
Local Network and Remote Network addresses for the “Glue Network,” the network that is created by the
administrator that serves as the “glue” between the networks of the tunnel. Each address must be a different IP
address from the same private network, and these addresses together form the endpoints of the tunnel.
Remote Gateway, the public facing WAN IP address that the local gateway is going to connect to.
Routes that allow you to configure what network traffic from local host(s) will be allowed through the tunnel.
Optionally, you might also want to enable the tunnel Keep Alive feature to monitor the status of a tunnel and more
accurately determine if the tunnel is alive or not.
Click Add to configure a new GRE tunnel; click Edit to make changes to an existing tunnel.

The user creates the IP address inputted here. It must be different from the IP addresses of the networks it is gluing
together. Choose any private IP address from the following three ranges that doesn’t match either network:
