Figure 148: GR E Tunnel Config uratio n Menu
This menu allows you to add or edit a tunnel.
The Tunnel Name field will be presented if the tunnel is being created. The tunnel
name is purely for informational purposes. A network routing device with this name
will be created. In order that the name not collide with those used by other interfaces,
it will be prefixed with “gre”.
The Remote Net field configures the target network whose traffic is forward through
the tunnel. It may be a individual IP address or subnetted IP address such as
192.168.0.0/24. The Remote Net must not used by another tunnel.
The Local IP field configures the IP address of the local end of the tunnel.
The Remote IP field configures the IP address of the local remote of the tunnel.

Note: E ach tunnel must hav e a unique combinati on of loc al and rem ote addres ses, or

it will not be ac tivated.

The Cost field configures the routing cost associated with networking routing that
directs traffic through the tunnel. The cost will default to zero if left unset.
The Local Egress Port configures a port to bind the tunnel to. If set, tunneled
packets will only be routed via this port and will not be able to escape to another
device when the route the to endpoint changes.
