Firewall Settings
A firewall protects your network from the outside world. The DIR-825 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 computercompletely to the outside world.

DMZ IP Address:
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.
mmmtm. .
Address Restricted - Incoming traffic must match the IP address I ”W“ “i
of the outgoing connection. . . ”mum: ‘"W””"“°*"E"'
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 ”a...“ .
can expose one computer to the Internet and run the application WNW
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 its 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.

Roufing
The Routing option is an advanced method of customizing specific routes of data through your network.
Destination IP: Enter the IP address of packets that will take
this route.
Nelmask: Enter the netmask of the route, please note
that the octets must match your destination _ mmwmxmmmwm“"’“‘“*‘”“""“"“W"“”m“
ip address, [E Mi
Gateway: Enter your next hop gateway to be taken if this
route is used.
Metric: The route metric is a value from 1 to 16 that
indicates the cost of using this route. A value 1
is the lowest cost and 15 is the highest cost.
Intertace: Select the interface that the IP packet must
use to transit out of the routerwhen this route
is used.

WISH Rules: A WISH Rule identifies a specific messageflow and assigns a priority to that flow. For most applications, the priority classifiers
ensure the right priorities and specific WISH Rules are not required.
WISH supports overlaps between rules. If more than one rule matches for a specific message flow, the rule with the highest
priority will be used.

Wi-Fi Protected Setup (WPS)
Wi-Fi Protected Setup (WPS) System is a simplified method for securing your wireless network during the “Initial setup”
as well as the “Add New Device” processes. The Wi-Fi Alliance (WFA) has certified it across different products as well
as manufactures. The process is just as easy, as depressing a button for the Push-Button Method or correctly entering
the 8-digit code for the Pin-Code Method. The time reduction in setup and ease of use are quite beneficial, while the
highest wireless Security setting of WPA2 is automatically used.
Enable: Enable the Wi-Fi Protected Setup feature.
Lock Wireless Locking the wireless security settings prevents the
Security Settings: settings from being changed by the Wi—Fi Protected
Setup feature ofthe router. Devices can still be added
to the network using Wi-Fi Protected Setup. However.
the settings of the network will not change once this
option is checked.
PIN Settings: A PIN is a unique numberthat can be used to add
the router to an existing network or to create a new
network. The default PIN may be printed on the
bottom of the router. For extra security, a new PIN
can be generated.You can restore the default PIN at
any time. Only the Administrator (“admin“ account)
can change or reset the PIN.
Current PIN: Shows the current value of the routers PIN.
Reset PIN tn
Default: Restore the default PIN of the router.

Add Wireless This Wizard helps you add wireless devices to the wireless network
Station:
The wizard will either display the wireless network settings to guide you through manual configuration, prompt you to enter
the PIN for the device, or ask you to press the configuration button on the device. Ifthe device supports Wi-Fi Protected Setup
and has a configuration button, you can add it to the network by pressing the configuration button on the device and then
the on the router within 60 seconds. The status LED on the router will flash three times if the device has been successfully
added to the network.
There are several ways to add a wireless device to your network. A “registrar' controls access to the wireless network. A
registrar only allows devices onto the wireless network if you have entered the PIN, or pressed a special Wi-Fi Protected Setup
button on the device The router acts as a registrar for the network, although other devices may act as a registrar as well.
