7.3 MAC Filtering
When you enable the MAC Filtering function, you can specify the MAC
Addresses in current filter table. Once the source MAC Address of outgoing packets match the MAC Addresses in
the table, the firewall will block this packet from LAN to WAN.
7.4 Port Forwarding (Virtual Server)
This function allows you to automatically redirect common network services to a specific machine behind the NAT
firewall. These settings are only necessary if you wish to host some sort of server like a web server or mail server
on the private local network behind the device's NAT firewall.
