Packet Filter
"Packet Filter" function can let you define some filtering rules for incoming and outgoing packets. So
the router can control what packets are allowed or blocked to pass through it. A packet filter rule should
indicate from and to which interface the packet enters and leaves the router, the source and destination
IP addresses, and destination service port type and port number. In addition, the time schedule to which
the rule will be active.
