Filter:
The second tab on the dialog box is Filter. This is a one-way protocol filtering
mechanism that prevents the AP from transmitting certain protocols from the
Wired Ethernet LAN into the Wireless zone. If you do not require particular
protocols on the wireless part of your network, you can save bandwidth by
enabling the protocol filter.
From the
Filter
tab, some, all, or none of the protocols listed may be selected for
filtering out:
•
IP protocol
•
IPX protocol
•
NetBEUI protocol
•
AppleTalk protocol
•
Other protocol
Selecting a protocol for filtering will activate the AP s protocol filtering
immediately on clicking
OK
. Clicking on
Reset
is not required. If, after filtering a
protocol, your network is not functioning as before, it s likely the protocol is
required on the network and you should disable the filter for that protocol.
Access Control:
Access Control is the next tab on the box (
Figure 23
). The AP’s access control is
managed by a control table on the Access Point (AP).
Figure 23. AP Setting/Access Control
The first time this box is opened, the table will be empty. This means that there are
no restrictions on who can access and reconfigure the AP and any user may modify
the AP’s operation. This is like going on vacation and leaving your front door
open. To avoid chaos on the network, access to the AP configurations should be
restricted to only those for whom it is absolutely necessary. First enter your IP
address and then set your own access rights to
Read/Write
(see the note below).
