set a WLAN name (SSID) and key for the Mobile Broadband, and enter the key on the
client. WPS automatically configures an SSID and key for the Mobile Broadband and
client. You can conveniently and securely connect your client to the WLAN without
having to remember the SSID and key.

Configuring a Special Application
The Mobile Broadband supports the function to use a special application to configure
dynamic port forwarding. Certain applications in the local area network (LAN) must use
a specified port of the firewall to access remote applications. To set up a Transmission
Control Protocol and User Datagram Protocol (TCP/UDP) connection between an
application in the LAN and a remote application, the firewall uses this port forwarding
function to open the required port.

Example of the Configuration of a Special Application
A client in the LAN uses TCP to access the MSN game server through port 47624. When
the game starts, the game server uses TCP and port 2400 to set up a connection to the
client that tries to access the server. In this case, you must configure dynamic port
forwarding, because the game conflicts with the following default firewall rules:
 The firewall blocks external data input.
 The game server can send a connection request to the external IP address of the
Mobile Broadband but cannot send the request to the LAN client that tries to access
the game server, because the IP addresses of clients are not open to external devices.
To solve this problem, you must define a set of port forwarding rules. When the client in
the LAN sends data to TCP port 47624, the rules allow data input from TCP port 2400.

If external users cannot access certain network services provided by the local area

client that provides the required network services as the DMZ host; external users can
then access these services properly. DMZ is an acronym for the demilitarized zone in
networks.
DMZ users are not protected by the firewall and may be easily attacked. In addition, the
security of other users in the LAN is compromised.

 Enable: to enable the DMZ function.

Network address translation is the process of modifying source and destination IP
addresses when IP packets are transmitted across a router or firewall. The purpose of this

settings as required.
