Destination IP Address – Enter the incoming or outgoing packet’s destination IP
address(es).
Destination Port – Check the TCP or UDP packet’s destination port number(s).
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.
• 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.
Active – Select Yes from the drop down list box to enable MAC address filtering.
Action When Matched – Select Drop or Forward.
Log – Choose Yes if you wish to generate logs when the filer rule is applied to a packet.
MAC Address – Enter the MAC addresses you wish to manage.
