The following section deals with configuration for the network’s firewall as well as its packet
filtering. Available criteria for packet filtering are based on MAC address (Wired or Wireless),
Ethernet packet, and IP address. These filtering methods provide security, preventing

Data packets will be filtered (classified) as either
“allowed packets” or “denied packets”;
the
“allowed packets” mode is more commonly known as the “whitelist” and the “denied
packets” mode is known as the blacklist. We highly encourage you to be extremely careful on
