DI-LB604 User’s Manual

Introduction

The D-Link Express EtherNetwork DI-LB604 is a 4-port Ethernet Broadband Router. The D-Link DI-LB604 enables users to quickly and easily share a high speed Internet connection. The D-Link DI-LB604 also incorporates many advanced features, traditionally found in more expensive routers.

After completing the steps outlined in the Quick Installation Guide (included in your package) you will have the ability to share a single Internet connection as well as sharing information and resources such as ﬁles and printers. The DI-LB604 is compatible with most popular operating systems, including Macintosh, Linux and Windows, and can be integrated into an existing network. This Manual is designed to help you connect the D-Link Express EtherNetwork DI-LB604 to a high speed Internet connection and 4 Ethernet PC connections. This manual provides a quick introduction to Broadband Router Technology, Firewalls, and Local Area Networking. Please take a moment to read through this manual and get acquainted these various technologies.

Introduction

D-Link Systems, Inc.

DI-LB604 User’s Manual

Features and Beneﬁts

 Connects multiple computers to a Broadband (Cable or DSL) modem to share

the Internet connection.

 Allows you to quickly and easily share an Internet connection with multiple

computers and devices.

 Supports multiple and concurrent IPSec and PPTP pass-through sessions, so

multiple users behind the DI-LB604 can access corporate networks through various VPN clients more securely.

 The Web-Based user interface displays a number of advanced network

management features including:

 Easily applied content ﬁltering based on MAC Address, IP Address, URL and/or

Domain Name.

 These ﬁlters can also be scheduled to be active on certain days or for a duration

of hours or minutes.

 NAT allows you to share a single IP Address and protects you from outside

intruders gaining access to your private network.

Features and Beneﬁts

 All of the networked computers can retrieve TCP/IP settings automatically from

the DI-LB604.

 DI-LB604 is conﬁgurable through any network computer’s web browser using

Netscape or Internet Explorer.

 Allows you to assign different access rights for different users.

 Enables you to expose WWW, FTP and other services on your LAN to be

accessible to Internet users.

 Special applications requiring multiple connections, like Internet gaming, video

conferencing, Internet telephony and so on. The DI-LB604 can sense the application type and open a multi-port tunnel for it.

 Allows a networked computer to be fully exposed to the Internet. This function is

used when the Special Application feature is insufﬁcient to allow an application to function correctly.

Select the WAN port that you would like these port options to apply to.

The largest amount of data that can be transferred across a given physical network.

There are three methods, ICMP, HTTP and Trafﬁc, provided for device to check if WAN interfaces are connected to internet or not. A successful response of either method means that the connection is OK. If the choosen method fails, the connection is considered to be down.

D-Link Systems, Inc.

DI-LB604 User’s Manual

Using the Conﬁguration Menu

Method:

ICMP:

The health checking is performed by sending an ICMP

echo request packet to the speciﬁc destination.

The speciﬁc destination (“Alive Indicator”) could be either :

1. if the input box is ﬁlled (NAME or IP address): the host is used.

2. if the input box is left blank: gateway of wan interface will be used.

If one ICMP echo reply packet from Alive Indicator or gateway is received, the connection is considered OK. If there are no response received after 4 tries, the connection is considered to be down.

HTTP:

Trafﬁc:

The device gets a TCP connection with the Indicator ﬁrst. packet to the Alive Indicator. If any HTTP DATA from the Alive Indicator is received, the connection is considered OK. If there are no response received after 5 tries, the connection is considered to be down.

If there is no trafﬁc on the WAN port in the Interval time, the connection is considered to be down.

Then the device sends HTTP HEAD

Echo Retry:

The period to check if the WAN port is alive or not.

This is used for the ICMP or HTTP methods to determine if

your Internet connection is active or not.(You can either ﬁll-out the IP address or host name)

To enable or disable auto dialup for a PPPoE/PPTP connection. If you decide not to use auto dialup or auto disconnect, then you have to connect/disconnect manually.

The amount of time the router will wait before it disconnects if there is no trafﬁc on the connection. Enter -1 to keep the connection always alive. Enter 0 to enable ‘dial on demand by trigger’.

To determine how often an Echo request is sent to the PPPoE

server. Normally, leave this setting as its default value.

To determine the most times that the Echo request is allowed to

be sent to the PPPoE server until getting a response. Normally, leave this setting as its default.
