Website Filters are used to deny LAN computers from accessing speciﬁc web sites by the URL or domain. A URL is a

specially formatted text string that deﬁnes a location on the Internet. If any part of the URL contains the blocked word,

the site will not be accessible and the web page will not display. To use this feature, enter the text string to be blocked

and click

The Inbound Filter option is an advanced method of controlling data received from the Internet. With this feature you

can conﬁgure inbound data ﬁltering rules that control data based on an IP address range.

Inbound Filters can be used

with Virtual Server, Port Forwarding, or Remote Administration features.

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.

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.

A ﬁrewall protects your network from the outside world. The D-Link DIR-635 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.

Application Level Gateway (ALG) Conﬁguration

Here you can enable or disable ALG’s. Some protocols and applications require special handling of the IP payload to

make them work with network address translation (NAT). Each ALG provides special handling for a speciﬁc protocol

or application. A number of ALGs for common applications are enabled by default.

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 adminstrator of your corporate network whether

your VPN client supports NAT traversal.

Allows applications that use 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 all of the Windows/MSN Messenger functions to work properly through the router.

Allows FTP clients and servers to transfer data across NAT. Refer to the Advanced > Virtual Server page if you want to

host an FTP server.

Allows Microsoft NetMeeting clients to communicate across NAT. Note that if you want your buddies to call you, you should

also set up a virtual server for NetMeeting. Refer to the Advanced > Virtual Server page for information on how to set up

a virtual server.

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.

Allows Ethernet network adapters with Wake-On-LAN (WOL) to function.

Allows Windows Media Player, using MMS protocol, to receive streaming media from the internet.

Transmit Power

1d Mode

W

M Mode

WDS Mode

Set the transmit power of the antennas.

Beacons are packets sent by an Access Point to

synchronize a wireless network. Specify a value.

100 is the default setting and is recommended.

This value should remain at its default setting of

2432. If inconsistent data ﬂow is a problem, only

a minor modiﬁcation should be made.

The fragmentation threshold, which is speciﬁed

in bytes, determines whether packets will be

fragmented. Packets exceeding the 2346 byte

setting will be fragmented before transmission.

2346 is the default setting.

(Delivery Trafﬁc Indication Message) 3 is the

default setting. A DTIM is a countdown informing

clients of the next window for listening to

broadcast and multicast messages.

This enables 802.11d opration. 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. Enable this option to 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.

When WDS is enabled, this router functions as a wireless bridge and is able to wirelessly communicate with other AP’s via

WDS links.

Note:

WDS is incompatible with WPA. Both features cannot be used at the same time. A WDS link is bidirectional so this AP must know the MAC

address (creates the WDS link) of the other AP, and the other AP must have a WDS link back to this AP (the router).
