Turning on Access Control to Restrict Access by MAC
Address
By default, any wireless PC that is configured with the correct SSID and WEP/WPA settings will
be allowed to access to your wireless network. For increased security, you can restrict access to the
wireless network to only allow specific PCs based on their MAC addresses.
You can restrict access to only trusted PCs so that unknown PCs cannot wirelessly connect to the
CGD24G gateway. MAC address filtering adds an obstacle against unwanted access to your
network, but the data broadcast over the wireless link is fully exposed.
To restrict access based on MAC addresses:
1. Log in to the gateway using its default address of http://192.168.0.1 or at whatever IP address
the unit is currently configured. Use the default user name of admin and default password of
password, or the password you have set up.
2. In the main menu, under Setup, select Wireless Settings. In the Wireless Settings screen,
select the Turn Access Control On check box (see Figure 2-11 on page 2-20).
3. When you enable access control, the access point only accepts connections from clients on the
selected access control list. This provides an additional layer of security.
4. Click the Setup Access List button to display the Wireless Card Access List screen.
Note: If you are configuring the gateway from a wireless computer, make sure to add
your computer’s MAC address to the Access List. Otherwise you will lose your
wireless connection when you click Apply. You must then access the gateway
from a wired computer, or from a wireless computer that is on the access
control list, to make any further changes.
