Page 1: General
Tunnel Name: Give the tunnel a name that uniquely
identifies it.
Tunnel Key: Enables an ID key for a GRE tunnel, which
can be used as an identifier for mGRE (Multipoint GRE).
Local Network: This is the local side of the "Glue
Network," a network created by the administrator to form
the 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:
• 10.0.0.0 - 10.255.255.255
• 172.16.0.0 - 172.31.255.255
• 192.168.0.0 - 192.168.255.255
Remote Network: This is the remote side of the "Glue
Network." Again, the user must create an IP address that
is distinct from the IP addresses of the networks that are
being glued together.
The Remote Network and Local Network values will be
flipped when inputted for the other side of the tunnel
configuration.
Subnet Mask: This is the subnet mask for the Glue
Network. The Local and Remote Network addresses must fit with this mask. 255.255.255.0 is a logical choice for most
users.
Remote Gateway: This is the public facing, WAN-side IP address of the network that the local gateway is going to
connect to.
