IP Filters

IP Filters allows you to block network access based on a user's computer IP Address on

the local LAN. You can use this option to block specific traffic (for e.g., block web access)

or any traffic from a computer on your local network.

If the

Block All Traffic

checkbox is checked, all network traffic from that computer will be

blocked. You can also add, edit or delete IP Filter rules without using the pre-defined

rules.

You will need to use

Custom IP Filters

when specifying IP subnets or IP address that is

not listed under

LAN Clients

. Otherwise, new filters can be defined in the

User Category

of the

Available Rules

, and then mapped to the appropriate WAN connection and LAN IP.
