Some applications require multiple connections, such as Internet gaming, video conferencing, and Internet telephony.

These applications have difﬁculties working through NAT (Network Address Translation). Application Rules makes

some of these applications work with the DIR-685. If you need to run applications that require multiple connections,

specify the port normally associated with an application in the “Trigger Port” ﬁeld. Select the protocol type as TCP or

UDP. Then enter the ﬁrewall (public) ports associated with the trigger port to open them for inbound trafﬁc.

Section 3 - Conﬁguration

Tick the checkbox to 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.

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.

Use this section to restrict external IP addresses

and applications from accessing your network.

This section also allows you to control the hosts/

applications that internal network devices can

have access to on the Internet.

Firewall Settings

A ﬁrewall protects your network from the outside world. The D-Link DIR-685 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 completely expose the chosen computer to the outside world.
