Firewall Settings - D-Link DIR-865L User Manual

Section 3 - Configuration
A firewall protects your network from the outside world. The DIR-865L offers a firewall type functionality. The SPI feature helps
prevent cyber attacks. Sometimes you may want a computer exposed to the outside world for certain types of applications.
If you choose to expose a computer, you can enable DMZ. DMZ is short for Demilitarized Zone. This option will expose the
chosen computer completely to the outside world.
Enable SPI:
SPI (Stateful Packet Inspection, also known as dynamic packet filtering)
helps to prevent cyber attacks by tracking more state per session. It
validates that the traffic passing through the session conforms to the
protocol.
NAT Endpoint
Select one of the following for TCP and UDP ports:
Filtering:
Endpoint.Independent.- Any incoming traffic sent to an open port will
be forwarded to the application that opened the port.
The port will close if idle for 5 minutes.
Address.Restricted.- Incoming traffic must match the IP address
of the outgoing connection.
Address.+.Port.Restriction - Incoming traffic must match the
IP address and port of the outgoing connection.
Anti-Spoof Check:
Enable this feature to protect your network from certain kinds of
"spoofing" attacks.
Enable DMZ:
If an application has trouble working from behind the router, you can
expose one computer to the Internet and run the application on that
computer.
Note: Placing a computer in the DMZ may expose that computer to a variety
of security risks. Use of this option is only recommended as a last resort.
DMZ IP Address:
Specify the IP address of the computer on the LAN that you want to have unrestricted Internet communication. If this computer
obtains it's IP address automatically using DHCP, be sure to make a static reservation on the Setup > Network.Settings page so
that the IP address of the DMZ machine does not change.
