Section 3 - Conﬁguration

A ﬁrewall protects your network from the outside world. The D-Link DIR-615 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.

Enable Anti-Spoof

Enable this option to provide protection from certain kinds of "spooﬁng"

Checking:

attacks.

Enable DMZ Host:

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.

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 System > Network Settings page so that the IP address of the

DMZ machine does not change.
