Port Forwarding Basics
Port forwarding is a way of configuring the AirStation so that incoming data is automatically directed to specific IP
addresses on the network based on the data type.
Common Uses
Port forwarding allows computers outside your network to access computers on your LAN.
Some applications require port forwarding. For example, if you set up a game server, people outside the network will
need to join your server to play the game with you. But the AirStation will automatically block all outside attempts to
connect to your LAN. By setting a port number (the port receiving all the connection requests) and the IP address of
your game server, the AirStation can then automatically direct the connection requests to the game server, allowing
others to join and play.
You will need to know specific ports and corresponding protocols to successfully configure port forwarding. Most
network applications and services will have the required ports and protocols in their user documentation.
Security
The risk of having a port “open” to the Internet depends entirely on the application using the open port. If no application
is currently connected to the port, all communications to the port will be ignored. Enabling a firewall or other security
application will also help reduce security risk.
UPnP
For the most part, manually configuring port forwarding rules is unnecessary with the advent of UPnP (Universal Plug
and Play). UPnP is a protocol that allows a connecting application or device to automatically request and configure a
port for you.
Many applications require that UPnP be enabled both in the application’s configuration and on the router. You can
enable UPnP on this AirStation by opening the Settings page, then navigating to

Setting Up Port Forwarding Rules
If UPnP is enabled, most programs will configure this for you automatically. Otherwise, you can manually set rules for
port forwarding. You can access port forwarding options by opening the AirStation’s Settings page and then navigating
to
Security
-
Port Forwarding
.
Creating Port Forwarding Rules
The AirStation can register up to 32 rules. Rules can be managed using the group feature.
Once a group has been created, you can add additional port forwarding rules to that group. You can also turn the group
of rules on or off as needed, or select a group of port forwarding rules to be disabled.
1
Create a new group name or add to an existing group.
2
Specify the WAN-side IP address the AirStation will forward ports from. Using the AirStation’s Internet IP address is
highly recommended, but you can manually enter an IP address.
3
Select a protocol and its corresponding port from the dropdown menu. For example, selecting HTTP will
automatically select TCP port 80. If you select any other protocol, you must select a valid port (from 1-65535)
as well. The default is TCP/UDP, along with a list of common protocols. If selected, the protocols will use a
corresponding port. You can also select Manual to manually enter a protocol and its corresponding port.
4
Enter the LAN–side IP address of the network computer to receive the forwarded data.
5
Enter the LAN-side port. This port will almost always be the same as the port set under Protocol. If the port is
different, this port will be used to route traffic on the LAN rather than the WAN port. As before, you can select a
port from 1-65535.
Once the rule has been added, it will be displayed under the “Forwarded Ports” section.

Managing Port Forwarding Rules
Individual rules cannot be turned off. Only a rule group can be shut off. You can click
Edit
to make any changes to
individual rules, or
Delete
to remove the rule entry.
Configuring a USB Drive as a NAS
You can use a USB drive as a network-attached storage (NAS) device by plugging it into the AirStation. The files on the
device can then be accessed from anywhere on the network.
Note:
Not all USB drives are compatible with the AirStation.
Setting Up the NAS
Make sure the USB drive is powered on.
1
Connect the USB drive to the AirStation.
2
On a computer, open a web browser and access the AirStation’s Settings page.
