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 to which the local gateway is going to
connect.
TTL: Set the Time to Live (TTL), or hop limit, for the GRE tunnel.
MTU: Set the maximum transmission unit (MTU) for the GRE tunnel.
WAN Binding: WAN Binding is an optional parameter used to configure the GRE tunnel to ONLY operate when the
specified WAN device(s) are available and connected. An example use case is when there is a router with both a
primary and failover WAN device and the tunnel should only be used when the system has failed over to the backup
connection.
Make a selection for "When," "Condition," and "Value" to create a WAN Binding. The condition will be in the form of these
examples:
When Condition Value
Port is USB Port 1
Type is not WiMAX
When:
Port – Select by the physical port on the router into which you are plugging the modem (e.g., "USB Port 2").
Manufacturer – Select by the modem manufacturer (e.g., "Cradlepoint Inc.").
Model – Set your rule according to the specific model of modem.
Type – Select by type of Internet source (Ethernet, LTE, Modem, Wireless as WAN, WiMAX).
Serial Number – Select a 3G or LTE modem by the serial number.
MAC Address – Select a WiMAX modem by MAC Address.
Unique ID – Select by ID. This is generated by the router and displayed when the device is connected to the
router.
Condition: Select “is,” “is not,” “starts with,” “contains,” or “ends with” to create your condition’s statement.
Value: If the correct values are available, select from the dropdown list. You may need to manually input the value.
Invert WAN Binding: Advanced option that inverts the meaning of WAN Binding to only establish this tunnel when the
specified WAN Binding device(s) are NOT connected.
