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 lters can be helpful in securing or restricting your local network.
The IP lter feature enables you to create rules that control the forwarding of incoming and outgoing data betwe-
en the LAN and WAN side.
You can create IP lter 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 dene an IP lter 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 in-
ternet 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 de-
stination), or denied (discarded), depending on the action specied in the rule.
The IP Filter Conguration page provides the capability to enable/disable the IP lter feature and the IP Filter rule
entries for all currently established rules.
