Net Service Filter can work in either White List or Black List mode. When running in White
List mode, it only lets certain packets get through the WiFi Router. While in Black List mode,
it only blocks certain packets passthrough.
Steps to set Net Service Filter:
1. From the navigation panel, go to Advanced> Security> IPv4 Firewall> Net Service Filter.
2. Enable Net Service Filter: Enable or disable this module.
3. Filter Table List: There are two kinds of filter list: White List, Black List. White
List can make WiFi Router serve the specified service defined
in the list, Black List make WiFi Router deny serving the
specified service.
4. Filtered ICMP packet types: This field defines a list of LAN to WAN ICMP packets type
that will be filtered. For example, if you would like to filter
Echo (type 8) and Echo Reply (type 0) ICMP packets, you
need to enter a string with numbers separated by blank, such
as [0 8].
