IP Filtering
When you enable the IP Filtering function, you can specify local IP
Addresses in current filter table. If you select “Accept” for the IP forwarding
default policy, once the source IP address of outgoing packets match the
IP address definition in the table, the firewall will block those packets form
LAN to WAN.
When you select “Drop” option for default policy, once the source IP
address of outgoing packets match the IP address definition in the table,
the firewall will allow those packets form LAN to WAN.
MAC Filtering
When you enable the MAC Filtering function, you can specify the MAC
Addresses in current filter table. If you select “Accept” for the IP forwarding
default policy, once the source MAC Address of outgoing packets match
the MAC Address definition in the table, the firewall will block those
packets form LAN to WAN.
If you select “Drop” for the IP forwarding default policy, once the source
MAC Address of outgoing packets match the MAC Address definition in
the table, the firewall will allow those packets form LAN to WAN.
NAT (Network Address Translation)
NAT is the translation between public IP address and private IP address.
While NAT is enabled, you can use port forwarding or DMZ option to redirect
your common network services. If you want to disable NAT, you can go to
Management-Route page to disable it and the functions of DMZ, Port
Forwarding will be disabled.
