IP Filters
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 computer 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.
IP Filters fields:
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.
