Section 3 - Conﬁguration

Firewall Settings

A ﬁrewall protects your network from the outside world. The D-Link DIR-628 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 cam enable DMZ. DMZ is short for Demilitarized Zone.

This option will expose the chosen computer completely to the outside world.

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.

Select one of the following for TCP and UDP ports:

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 this feature to protect your network from certain kinds of

“spooﬁng” attacks.

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.

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 Basic > DHCP page so that

the IP address of the DMZ machine does not change.
