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.
Tick this check box to enable DMZ.
Specify the IP address of the computer on the
LAN that you want to have unrestricted Internet
communication in this field. Use the drop-down
menu to specify a host that currently has a
DHCP lease from the DIR-604. If this computer
has obtained its IP address automatically using
DHCP, be sure to make a static reservation on
the LAN Setup page (
Setup
>
LAN Setup
) in
the DHCP Reservation section so that the IP
address of the DMZ machine does not change.
Tick to enable application level gateway (ALG)
configuration of RTSP.

Firewall & DMZ
A firewall protects your network from the outside world. The D-Link DIR-604 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 completely expose the chosen computer to the outside world.
