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.

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

page so that the IP address of the

DMZ machine does not change.

Allows multiple machines on the LAN to connect to their corporate network using PPTP protocol.

Allows multiple VPN clients to connect to their corporate network using IPSec. Some VPN clients support traversal of IPSec through

NAT. This ALG may interfere with the operation of such VPN clients. If you are having trouble connecting with your corporate network,

try turning this ALG oﬀ. Please check with the system administrator of your corporate network whether your VPN client supports

NAT traversal.

A ﬁrewall protects your network from the outside world. The DIR-826L 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.

SIP:

Allows application that uses Real Time Streaming Protocol to receive streaming media from the Internet. QuickTime and Real Player

are some of the common applications using this protocol.

Allows devices and applications using VoIP (Voice over IP) to communicate across NAT. Some VoIP applications and devices have

the ability to discover NAT devices and work around them. This ALG may interfere with the operation of such devices. If you are

having trouble making VoIP calls, try turning this ALG oﬀ.

Enter a name for your route.

Enter the IP address of packets that will take this

route.

Enter the netmask of the route, please note

that the octets must match your destination IP

address.

Enter your next hop gateway to be taken if this

route is used.

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.

Select the interface that the IP packet must use to

transit out of the router when this route is used.

Set the transmit power of the antennas.

This enables 802.11d operation. 802.11d is a wireless

speciﬁcation developed to allow implementation of

wireless networks in countries that cannot use the

802.11 standard. This feature should only be enabled

if you are in a country that requires it.

WMM is QoS for your wireless network. This will improve

the quality of video and voice applications for your

wireless clients.

Check this box to reduce the guard interval time

therefore increasing the data capacity. However, it’s less

reliable and may create higher data loss.

Enable this option to reduce interference from

other wireless networks in your area. If the channel

width is operating at 40MHz and there is another

wireless network’s channel over-lapping and causing

interference, the router will automatically change to

20MHz.

Wi-Fi Protected Setup (WPS)

Enable the Wi-Fi Protected Setup feature.

Note:

if this option is unchecked, the WPS button on the

side of the router will be disabled.

Check to disable the WPS PIN method of securing your

network. This will not aﬀect the Push-Button method.

A PIN is a unique number that can be used to add

the router to an existing network or to create a new

network. Only the Administrator (“admin” account) can

change or reset the PIN.

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 pressing 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.
