Configuring MAC Address Filtering
Follow these steps to configure MAC Address filtering.
1 Click the Firewall link in the navigation menu, then click MAC Address Filter-
ing.
The MAC Address Filtering window appears.
2 Click the Add button to add a blank row to the filter list.
3 Enter the MAC address of the computer you want to add to the filter. Do not
enter colons or dashes in between the hex digits. See the sidebar for infor-
mation about finding the MAC address of a computer.
Note: Make sure you enter the MAC address correctly. The Telephony Mo-
dem may completely block access if you enter an incorrect address.
4 Click the Save button to save your changes.
5 Proceed to Configuring the DMZ . Finding the MAC Address of a computer
Locate the operating system of the computer that you
want to add to the list and follow the instructions to find
its wireless MAC address.
Windows: open a Command Prompt window and type
ipconfig /all (and press Return). Locate the line that
begins with “Description” and contains the word “Wire-
less.” The next line, which starts with “Physical Address,”
contains a string of six hex numbers, separated by
dashes. This is the MAC address.
MacOS X: open a Terminal window and type ifconfig
(and press Return). Find the line that begins with “en1”
— this is the wireless adapter. The next line that begins
with “ether” contains the MAC address of the wireless
interface.
Linux: open a shell window and type ifconfig (and press
Return). The wireless interface is eth1 (unless there is no
Ethernet adapter, in which case the interface is eth0).
