Filters
Address Filters are used to block traffic to/from particular IP addresses. They can be used
to block IP addresses either on the Internet or on your local network. There are no pre-
defined address filter rules; you can add the filter rules to meet your requirements. There
are two kinds of address filters, one is inbound, and the other is outbound. The rules can
be set to prevent unauthorized users (hosts or network) to access the Internet from LAN
(outbound) and/or access LAN from the Internet (inbound).
Host IP Address:
This is the IP address you wish to block access to or from.
Host Subnet Mask:
This is the subnet mask for the IP address range you wish to block.
Direction:
Whether you want to block access to the Internet (“outbound”), from the
Internet (“inbound”) or both to and from the Internet (“both”).
Tip:
To block access to/from a single IP address, enter that IP address as the Host IP
Address
and use a Host Subnet Mask of “255.255.255.255”.
