4.4.6.2 IP Filters – Custom IP Filters
Customer IP Filters are different from Port forwards, or Block All traffic because they allow greater scopes of
IP addresses to be included in the block.
The Custom IP Filters function allows creation of up to 20 custom IP filtering entries to block specific services
or applications based on:
„ Source/Destination IP address and Netmask
„ TCP Port (ranges supported)
„ Protocol
„ TCP
„ UDP
„ TCP and UDP
„ ICMP
„ Any
„ Filter Name: Name of the IP filter rule you are about to create.
„ Enable: The Enable button is checked by default, meaning this rule is applied when you click on
the Apply button.
„ Source IP: Since IP filtering is for outgoing traffic, the source IP is the IP address on your LAN
side that you want to block network traffic from.
„ Source Netmask: Netmask of the source IP on your LAN side.
„ Destination IP: You can define the destination IP address to which your source IP will be banned
the access. Enter “0..0.0.0” for all.
