User Manual / MBR1200B
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
Port
Type
• 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 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.
Tunnel Enabled: Select to activate the tunnel.
Add/Edit Tunnel – Routes
Adding routes allows you to configure what types of network traffic from the local host or hosts will be
allowed through the tunnel.
Click Add Route to configure a new route. You will need to input the following information, defined by the
remote network:
• Network Address – This is the network address that is the destination of the route. This should be set to
the network address at the remote side of the tunnel.
• Netmask – This is the corresponding subnet mask of the network being defined (Default: 255.255.255.0).
You can set the tunnel to connect to a range of IP addresses or to a single IP address. For example, you could
input 192.168.0.0 and 255.255.255.0 to connect your tunnel to all the addresses of the remote network in
