Using the MAC Filtering menu, you can define up to 16 MAC address filters to prevent PCs
from sending outgoing TCP/UDP traffic to the WAN via their MAC addresses. This is useful
because a specific NIC’s MAC address never changes, unlike its IP address, which can be
assigned by a DHCP server or hard-coded to various addresses over time.
The MAC Filtering menu allows wireless client stations to connect over a wireless
connection in two ways:
!
By allowing all wireless station access.
!
By allowing only trusted PCs.
To access the MAC Filtering menu, click
Wireless
in the menu bar and then click the
MAC
Filtering
submenu. Figure 35 shows an example of the menu and Table 14 describes the
settings you can select.
Note:
The
MAC Filtering
submenu is not available in the menu bar if wireless operation is
disabled in the Wireless Basic Settings menu (see page 40).
