Configuring Your Wireless Card Access List

By default, any wireless PC that is configured with the SSID and WEP/WPA settings has 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.

To restrict access based on MAC addresses:

1.

Connect to the gateway and log in as described in

“Viewing or Changing Wireless Settings” on

page 2-4

.

2.

From the main menu, select Wireless Settings. The Wireless Settings screen displays as shown

in

Figure 2-1 on page 2-4

.

3.

Scroll down to the Wireless Card Access List and select the

Turn Access Control On

check

box.

When you turn on access control, the gateway only accepts connections from clients on the

selected access control list. This provides an additional layer of security.

4.

Click

Apply

to confirm this setting.

Note:

If your computer is connected wirelessly to the wireless voice gateway, be

careful about selecting the

Turn Access Control On

check box. If your

computer’s MAC address is not in the access control list, then you will lose

your wireless connection when you click

Apply

. You must then access the

wireless voice gateway from a wired computer, or from a wireless computer

that is on the access control list, to make any further changes.
