Schedule time: User can setup the time to use the packet filter.
Attention
If the DHCP server option is enabled, you must be very careful in assigning
IP addresses of a filtered private IP range to avoid conflicts because you do
not know which PC in the LAN is assigned which IP address. The easiest
and safest way is that the filtered IP address is assigned to a specific PC
that is not allowed to access an outside resource such as the Internet. You
configure the filtered IP address manually for this PC, but it stays in the
same subnet with the router.
4.3.4.2 Ethernet MAC Filter
A Ethernet MAC (Media Access Control) address is the unique network hardware identifier
for each PC on your network’s interface (i.e. its Network Interface Card or Ethernet card).
Using your router’s MAC Address Filter function, you can configure the switch to only accept
traffic from specified machines, or else to block specific machines from accessing your LAN.
There are no pre-defined MAC address filter rules; you can add the filter rules to meet your
requirements.
