IP Filter
The IP filtering feature allows you to block specific applications/services based on the
IP address of a LAN device. You can use the IP Filters page to block specific traffic
(for example, block web access) or any traffic from a host on your local network.
A database of predefined IP filters allows you to apply one or more filtering rules to
one or more members of a defined LAN group. You can view the rules associated with
a predefined filter and add the available rules for a given category. You can also
create, edit, or delete your own IP filter rules.
Select LAN Group: Select the LAN group to which the IP filters feature will be
applied.
LAN IP: Select the IP address in the given LAN group to which the IP Filters feature
will be applied.
Block All Traffic: When checked, complete network access is blocked for the specific
IP address.
Block Outgoing Ping: Blocking outgoing ping (ICMP) generated from a particular
LAN IP can be used if your host has a virus that attempts a Ping-of-Death Denial
of Service attack.
Click Apply to complete the setup. Click Save All to save the changes.
Custom IP Filters
The Custom IP Filters page allows you to define up to 20 custom IP filtering entries to
block specific services or applications based on:

• TCP port (ranges supported)
