8. Click Apply.
9. Reboot.
You do not need to reboot immediately, if you have additional changes to
make, but port forwarding does not take effect until the device is rebooted.
An unsolicited TCP and UDP data request coming in to the AirLink device on port
8080 is forwarded to the LAN connected device, 192.168.13.30, at port 80. In
addition, unsolicited data requests coming in from the Internet on ports 8081,
8082, 8083, 8084, and 8085 are forwarded to ports 81, 82, 83, 84, and 85
respectively.

DMZ

The DMZ is used to direct unsolicited inbound traffic to a specific LAN device
such as a computer running a web server or other internal application. The DMZ
with public mode is particularly useful for certain services like VPN, NetMeeting,
and streaming video where the remote server may require a WAN connection to
the LAN device rather than being NATed by the router. In public mode unsolicited
traffic to hosts in the DMZ is permitted by default.
Options for DMZ are Automatic, Manual, and Disable.
Automatic uses the first connected host. If more than one host is available
(multiple Ethernet on a switch connected to the device and/or Ethernet with
USBnet) and you want to specify the host to use as the DMZ, select Manual and
enter the IP address of the desired host.
