IP Filtering
Entries in this table are used to restrict certain types of data
packets from your local network to Internet through the
Gateway. Use of such filters can be helpful in securing or
restricting your local network.
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).
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.
