IP Filtering
15
The IP filter feature enables you to create rules that control the forwarding of incoming and
outgoing data Between the LAN and WAN side.
You can create IP filter rules to block attempts by certain computers on your LAN to access
certain types of data or Internet locations. You can also block accesses to your LAN computers
from the WAN side.
When you define an IP filter rule and enable the feature, you instruct the ADSL/Ethernet router
to examine data packets to determine whether they meet criteria set forth in the rule. The
criteria can include the network or internet protocol, the packet carries, the direction in which it
is traveling (for example, from the LAN to the WAN and vice versa). The source IP address, the
destination IP address, and other characteristics of the packet data.
If the packet matches the criteria established in a rule, the packet can either be accepted
(forwarded towards its destination), or denied (discarded), depending on the action specified in
the rule.
The IP Filter Configuration page provides the capability to enable/disable the IP filter feature and
the IP Filter rule entries for all currently established rules. Click on the icons to edit, delete, of the
defined rule. Click add to create new IP Filter rules.
