IP Filter
IP Filter blocks the LAN to WAN packet exchanges and restricts devices from using specific
network services.
For example, if you do not want the device to use the Internet service, key in 80 in the destination
port. The traffic that uses port 80 will be blocked (but https cannot be blocked).
Leave the source IP field blank to apply this rule to all LAN devices.
Black List Duration: During the scheduled duration, clients in the Black List cannot use the
specified network services. After the specified duration, all the clients in LAN can access the
specified network services.
White List Duration: During the scheduled duration, clients in the White List can ONLY use the
specified network services. After the specified duration, clients in the White List and other
network clients will not be able to access the Internet or any Internet service.
NOTE: If you set the subnet for the White List, IP addresses outside the subnet will not be able to
access the Internet or any Internet service.
