Packet filters
The Packet Filter function allows you to define filtering rules for incoming and outgoing packets effectively controlling which
packets are allowed or blocked from passing through it. A packet filter rule can indicate which interface the packet uses to
enter and leave the router, the source and destination IP addresses, and the destination service port type and port number.
In addition, you can be schedule a rule to be active or inactive at specified times.
6.2.1.1
Packet Filter with White List Scenario
As shown in the diagram above, specify "Packet Filter Rule List" as white list (Allow those matching the following rules) and
define the rules. Rule-1 is to allow HTTP packets to pass, and Rule-2 is to allow HTTPS packets to pass.
Under such configuration, the router will allow only HTTP and HTTPS packets, issued from the IP range 192.168.123.200 to
250, which are targeted to TCP port 80 or 443 to pass the WAN interface.
