Security Configuration
Rev 2.3 Feb.12 85
The following is an example of configuring a port forward rule for a port forwarding
range of 5 ports on an Ethernet connected device:
1. Set number of PF entries to 1.
2. Click on “Add More” to display a rule line.
3. Enter 8080 for the public start port.
4. Select Ethernet as the Host I/F.
5. Enter 192.168.13.100 as the Host IP.
6. Enter 80 as the private port.
An unsolicited data request coming in to the AirLink device on port 8080, will be
forwarded to the LAN connected device, 192.168.13.100, at port 80.
Example of configuring the DMZ on an Ethernet connected device:
1. Enter 192.168.13.100 for the DMZ IP.
2. Select Ethernet as the Default Interface.
An unsolicited data request coming in to the AirLink device on any port, will be
forwarded to the LAN connected device, 192.168.13.100, at the same port.
Note: The DMZ settings are independent of the number of Port Forward entries and can
be used with port forwarding to pass anything not forwarded to specific ports.
Field Description
DMZ Enabled The AirLink device allows a single client to connect to the Internet through a demilitarized
zone (DMZ). Options are Automatic, Manual, and Disable. Default: Automatic.
• Automatic - enables the first connected host or the Public Mode interface as the DMZ.
• Manual - inserts a specific IP address in the DMZ IP field
• Disable - no connected host receives unsolicited traffic from the cellular network or
Internet.
DMZ IP This field only displays if Manual is selected for the DMZ Enabled field; this field does not
display if the DMZ is disabled. This is the IP address of the private mode host that should
be used as the DMZ.
DMZ IP in use IP address of the host to which inbound unsolicited packets will be sent.
When the device passes the Network IP to the configured public host, the DMZ IP in Use
displays the public IP.
Port Forwarding
Enabled
Enables port forwarding rules. Options are Enable and Disable.
Default: Disable.
Port Forwarding
Public Start Port A single port on the public network (cellular network accessible).
Host I/F The protocol to be used with the forwarded port: TCP or UDP. Only connections of that type
on that port will be forwarded.
Host IP IP address of a device connected to the Host I/F interface.
Private Port The single port on the device at the Host IP.
