Introduction The D-Link Express EtherNetwork DI-604 is a 4-port Ethernet Broadband Router. The D-Link DI-604 enables users to quickly and easily share a high speed Internet connection. The D-Link DI-604 also incorporates many advanced features, traditionally found in more expensive routers.
Content Filtering Easily applied content filtering based on Mac Address, IP Address, URL and/or Domain Name. Filter Scheduling These filters can also be scheduled to be active on certain days or for a duration of hours or minutes. Network Address Translation NAT allows you to share a single IP Address and protects you from outside intruders gaining access to your private network. DHCP Server Supported All of the networked computers can retrieve TCP/IP settings automatically from the DI-604.
server to show you the next page. The information that is sent and received from your computer is moved from your computer to the server using routers. A router also determines the best route that your information should follow to ensure that the information is delivered properly. A router controls the amount of data that is sent through your network by eliminating information that should not be there.
a 10Mbps network card, or 10/100Mbps network card, or a wireless network card. Most networks use hardware devices such as hubs or switches that each cable can be connected to in order to continue the connection between computers. A hub simply takes any data arriving through each port and forwards the data to all other ports. A switch is more sophisticated, in that a switch can determine the destination port for a specific piece of data.

Using the Configuration Menu Setup Wizard The Setup Wizard page is the first page that appears when logging into the web-based management interface. The Setup Wizard is a utility used to quickly configure the DI-604. It will guide you through four quick and basic steps to help you connect to your ISP. You will be connected to your ISP (Internet Service Provider) and have Internet access within minutes. WAN WAN is short for Wide Area Network. The WAN settings can be referred to as the Public settings.
HOME > WAN > DYNAMIC IP Address Choose Dynamic IP Address to obtain IP address information automatically from your ISP. Select this option if your ISP does not give you any IP numbers to use. This option is commonly used for Cable modem services. Host Name: The Host Name field is optional but may be required by some ISPs. The host name is the device name of the Broadband Router. MAC Address: The default MAC address is set to the WAN's physical interface MAC address on the Broadband Router.
HOME > WAN > Static IP Address Choose Static IP Address if all WAN IP information is provided to you by your ISP. You will need to enter in the IP address, subnet mask, gateway address, and DNS address(es) provided to you by your ISP. Each IP address entered in the fields must be in the appropriate IP form, which are four IP octets separated by a dot (x.x.x.x). The Router will not accept the IP address if it is not in this format. IP Address: Public IP address provided by your ISP.
HOME > WAN > PPPOE Please be sure sure to remove any existing PPPoE Client Software installed on your computers. Choose PPPoE (Point to Point Protocol over Ethernet) if you’re ISP uses PPPoE connection. Your ISP will provide you with a username and password. This option is typically used for DSL services. Select Dynamic PPPoE to obtain an IP address automatically for your PPPoE connection. Select Static PPPoE to use a static IP address for your PPPoE connection.
Maximum Idle Time: The amount of time of inactivity before disconnecting your PPPoE session. Enter a Maximum Idle Time (in minutes) to define a maximum period of time for which the Internet connection is maintained during inactivity. If the connection is inactive for longer than the defined Maximum Idle Time, then the connection will be dropped. Either set this to zero or enable Auto-reconnect to disable this feature. MTU: MTU stands for Maximum Transmission Unit.
Enter in the IP address information provided to you by your ISP. You will need to enter in My IP Address, My Subnet Mask, Server IP Address, Primary DNS, the Account and password provided to you by your ISP. My IP Address: IP address provided by your ISP. My Subnet Mask: Subnet mask provided by your ISP. Server IP Address: Server IP Address provided by your ISP.
Retype Password: Re-enter PPTP password Connection ID: Connection ID provided by your ISP (optional) Maximum Idle Time: The amount of time of inactivity before disconnecting your PPPoE session. Enter a Maximum Idle Time (in minutes) to define a maximum period of time for which the Internet connection is maintained during inactivity. If the connection is inactive for longer than the defined Maximum Idle Time, then the connection will be dropped.
Enter in the UserName, Password, Login Server IP provided to you by your ISP. UserName: User Name provided to you by your ISP Password: Password provided to you by your ISP Retype Password: Re-enter BigPond Cable password Login Server IP: Login Server IP provided to you by your ISP (Optional). Auto-Reconnect: If enabled, the Broadband Router will automatically connect to your ISP after your system is restarted or if the connection is dropped.
HOME > LAN LAN is short for Local Area Network. This is considered your internal network. These are the IP settings of the LAN interface for the DI-604. These settings may be referred to as Private settings. You may change the LAN IP address if needed. The LAN IP address is private to your internal network and cannot be seen on the Internet. IP Address: The IP address of the LAN interface. The default IP address is 192.168.0.1. Subnet Mask: The subnet mask of the LAN interface.
HOME > DHCP DHCP stands for Dynamic Host Control Protocol. The DI-604 has a built-in DHCP server. The DHCP Server will automatically assign an IP address to the computers on the LAN/private network. Be sure to set your computers to be DHCP clients by setting their TCP/IP settings to “Obtain an IP Address Automatically.” When you turn your computers on, they will automatically load the proper TCP/IP settings provided by the DI-604.
ADVANCED > VIRTUAL SERVER The DI-604 can be configured as a virtual server so that remote users accessing Web or FTP services via the public IP address can be automatically redirected to local servers in the LAN network. The DI-604 firewall feature filters out unrecognized packets to protect your LAN network so all computers networked with the DI-604 are invisible to the outside world. If you wish, you can make some of the LAN computers accessible from the Internet by enabling Virtual Server.
Each virtual service that is created will be listed at the bottom of the screen in the Virtual Servers List. There are already pre-defined virtual services already in the table. You may use them by enabling them and assigning the server IP to use that particular virtual service. Name: The name referencing the virtual service. Private IP: The server computer in the LAN network that will be providing the virtual services. Private Port: The port number of the service used by the Private IP computer.
Example #2: If you have an FTP server that you wanted Internet users to access by WAN port 2100 and only during the weekends, you would need to enable it as such. FTP server is on LAN computer 192.168.0.30. FTP uses port 21, TCP. Name: FTP Server Private IP: 192.168.0.30 Protocol Type: TCP Private Port: 21 Public Port: 2100 Schedule: From: 01:00AM to 01:00AM, Sat to Sun All Internet users who want to access this FTP Server must connect to it from port 2100.
Some applications require multiple connections, such as Internet gaming, video conferencing, Internet telephony and others. These applications have difficulties working through NAT (Network Address Translation). Special Applications makes some of these applications work with the DI-604.
ADVANCED > FILTER > IP FILTERS Filter Filters are used to deny or allow LAN computers from accessing the Internet. The DI-604 can be setup to deny internal computers by their IP or MAC addresses. The DI-604 can also block users from accessing restricted web sites. IP Filters Use IP Filters to deny LAN IP addresses from accessing the Internet. You can deny specific port numbers or all ports for the specific IP address. IP: The IP address of the LAN computer that will be denied access to the Internet.
ADVANCED > FILTER > MAC FILTERS Use MAC Filters to allow or deny LAN computers by their MAC addresses from accessing the Internet. You can either manually add a MAC address or select the MAC address from the list of clients that are currently connected to the Broadband Router.
ADVANCED > FILTER > URL BLOCKING URL Blocking is used to deny LAN computers from accessing specific web sites by its URL. 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.
ADVANCED > FILTER > DOMAIN BLOCKING Domain Blocking is used to allow or deny LAN computers from accessing specific domains on the Internet. Domain blocking will deny all requests to a specific domain such as http and ftp. It can also allow computers to access specific sites and deny all other sites.
ADVANCED > FIREWALL Firewall Rules is an advance feature used to deny or allow traffic from passing through the Broadband Router. It works in the same way as IP Filters with additional settings. You can create more detailed access rules for the DI-604. When virtual services are created and enabled, it will also display in Firewall Rules. Firewall Rules contains all network firewall rules pertaining to IP (Internet Protocol).
ADVANCED > DDNS Dynamic DNS (Domain Name Service) is a method of keeping a domain name linked to a changing (dynamic) IP address. With most Cable and DSL connections, you are assigned a dynamic IP address and that address is used only for the duration of that specific connection. With the DI-604, you can setup your DDNS service and the DI-604 will automatically update your DDNS server every time it receives a different IP address. Provider :Select from the list of DDNS servers available.
ADVANCED > DMZ If you have a client PC that cannot run Internet applications properly from behind the DI-604, then you can set the client up to unrestricted Internet access. It allows a computer to be exposed to the Internet. This feature is useful for gaming purposes. Enter the IP address of the internal computer that will be the DMZ host. Adding a client to the DMZ (Demilitarized Zone) may expose your local network to a variety of security risks, so only use this option as a last resort.
TOOLS > ADMIN Admin At this page, the DI-604 administrator can change the system password. There are two accounts that can access the Broadband Router’s Web-Management interface. They are admin and user. Admin has read/write access while user has read-only access. User can only view the settings but cannot make any changes. Remote Management Remote Management allows the DI-604 to be configured from the Internet by a web browser.
IP Address: Internet IP address of the computer that has access to the Broadband Router. If the IP address is set to * (star). This allows any Internet IP address to access the Broadband Router. It is not recommended that you set the IP address to * (star), because this allows any Internet IP address to access the Broadband Router, which could result in a loss of security for your network. If you elect to enable Remote Management, enter the IP Address of your remote location.
zone. If you manually set the time, you may also set Daylight Saving dates and the system time will automatically adjust on those dates. TOOLS > SYSTEM System Settings The current system settings can be saved as a file onto the local hard drive. The saved file or any other saved setting file can be loaded back on the Broadband Router. To reload a system settings file, click on Browse to browse the local hard drive and locate the system file to be used.
TOOLS > FIRMWARE Firmware Upgrade You can upgrade the firmware of the Broadband Router at this page. Make sure the firmware you want to use is on the local hard drive of the computer. Click on Browse to browse the local hard drive and locate the firmware to be used for the update.
TOOLS > MISC. Miscellaneous Items These are additional tools and features of the Broadband Router. Ping Test This useful diagnostic utility can be used to check if a computer is on the Internet. It sends ping packets and listens for replies from the specific host. Restart Device If for any reason the Broadband Router is not responding correctly, you may want to restart the Broadband Router.
Block WAN Ping When you “Block WAN Ping”, you are causing the public WAN IP address on the Broadband Router to not respond to ping commands. Pinging public WAN IP addresses is a common method used by hackers to test whether your WAN IP address is valid. Discard PING from WAN side: By enabling this option, the DI-604 will not reply to ping (ICMP) request packets from the Internet.
STATUS > DEVICE INFORMATION This page displays the current information for the Broadband Router. It will display the WAN, LAN, and MAC address information. If your WAN connection is set up for Dynamic IP address, there will be a Release button and Renew button. Use Release to disconnect from your ISP and use Renew to connect to your ISP. If your WAN connection is set up for PPPoE, there will be a Connect button and Disconnect button.
