MAC Filter
The Security Menu includes the MAC Filter screen.
IMPORTANT
Do not enable MAC filtering unless you have added your own computer’s MAC
address to the trusted client list. Otherwise you will be unable to access the device.
The MAC Filter screen enables you to allow specific devices to connect to MiFi 2200’s wireless
network. For example, if you put the MAC address for your WiFi-enabled mobile phone and the MAC
addess for your computer in the MAC Filter Trusted Client List, then only those devices can connect
to MiFi 2200.
Trusted devices still need the correct network name (SSID) and network key (WiFi passkey).
NOTE 
The MAC address on the Windows operating system is called the
Physical Address
.
Enable MAC Filter
This checkbox enables or disables the MAC Filter feature.
When the feature is
enabled
(checked), you must add the MAC address for the device to the
Trusted Client List. If a device not in the list tries to connect to the MiFi 2200 wireless network, the
connection is blocked even if the device has the correct network name (SSID) and network key (WiFi
passkey).

When the feature is
disabled
(un-checked), any device with the correct network name (SSID) and
network key (WiFi passkey) can connect to the MiFi 2200 wireless network.
Find the MAC Address on a Computer
The Media Access Controller (MAC) Address is also known as a hardware or physical address for a
device (usually a network adapter). It consists of six pairs of numbers and letters (for example,
00-21-9B-1C-64-34).
You can view the MAC address for any device connected to the MiFi wireless network from the WiFi
screen. [See
WiFi
(page 38).

Tip! 
You can cut and paste your computer’s MAC address from the WiFi Clients section of the WiFi screen.
If the computer is not connected to the MiFi wireless network, you can find the MAC address

Port filtering blocks outgoing Internet connections. You can set a list of Allowed Applications to only
allow certain programs to connect to the Internet.

Applications list to allow that application to connect to the Internet. For example, if you select VPN
in the Allowed Applications list but do not select HTTP, you can connect to a VPN server but you
cannot connect to a web page using your Internet browser.
When the feature is
