To allow traffic from the internet to enter your local network, you will need to open up ports or the router will block the request.

Because our routers use NAT (Network Address Translation), you can only open a specific port or ports to one computer at a time. For example: If you have 2 web servers on your network, you cannot open port 80 to both computers. You will need to configure 1 of the web servers to use port 81. Now you can open port 80 to the first computer and then open port 81 to the other computer.

For the DI-514, DI-524, DI-604, DI-614+, DI-624, DI-704P (revC), DI-704UP, DI-754, DI-764, DI-774, and DI-784:

Step 1: Open your web browser and enter the IP address of your D-Link router (192.168.0.1). Enter username (admin) and your password (blank by default).

Step 2: Click on the Advanced tab at the top and then click Virtual Server on the left side.

Step 3: Check Enabled to activate entry.

Step 4: Enter a name for your virtual server entry.

Step 5: Next to Private IP, enter the IP address of the computer on your local network that you want to allow the incoming service to.

Step 7: Enter the port information next to Private Port and Public Port. The private and public ports are usually the same. The public port is the port seen from the WAN side, and the private port is the port being used by the application on the computer within your local network.

Step 8: Enter the Schedule information.

Step 9: Click Apply and then click Continue.

For DI-704P (rev.B), DI-707P, DI-714P+, DI-804HV, DI-808HV, and DI-824VUP users:

Step 1: Open a web browser and enter the IP address of your router (192.168.0.1). Enter admin for your username and then your password (blank by default).

Step 2: Click on the Advanced tab and then Virtual Server on the left side.

Step 3: Enter the following information:

Check the box next to Enable.
Next to Service Ports, enter the port or range of ports you want to open.
Next to Service IP, enter the IP address of the computer you want to open the port to.
Click Always next to Schedule or enter the time frame that you want.

Step 4: Click Apply and then click Restart to save your changes.

client mode

Client Mode allows the D-Link DWL-2100AP to become a wireless client to another AP or wireless router. Client mode allows any device with an Ethernet connection to connect to your wireless network, such as a printer, gaming console (Xbox, PS2), or a computer.

You will need the MAC address of the device you want to be a client to. If you are connecting to a wireless router, then you must use the LAN or Ethernet MAC address, not the wireless address.

Step 1: Connect the DWL-2100AP to your PC using an Ethernet cable. You cannot connect to the DWL-2100AP wirelessly when in client mode.

Step 2: Your computer will need to be in the same IP address range as the DWL-2100AP for configuration. The default IP address is 192.168.0.50.

Step 3: Open a web browser and enter in the IP address of the access point (192.168.0.50). The username is admin (all lower case) and the password is blank (nothing).

Step 4: Click on Advanced at the top and then click Mode on the left side. At the bottom, click the AP Client button. Enter the MAC address of the device you want to repeat (IE 50:23:AB:D4:56:E1).

repeater mode

You will need the MAC address of the device you want to repeat. If you are repeating a wireless router, then you must use the LAN or Ethernet MAC address, not the wireless address.

Step 1: Connect the DWL-2100AP to your PC using an Ethernet cable. You cannot configure the DWL-2100AP wirelessly when in repeater mode.

Step 2: Your computer will need to be in the same IP address range as the D-Link DWL-2100AP for configuration. The default IP address is 192.168.0.50.

Step 3: Open a web browser and enter in the IP address of the access point (192.168.0.50). The username is admin (all lower case) and the password is blank (nothing).

Step 4: Click on Advanced at the top and then click Mode on the left side. At the bottom, click the AP Repeater button. Enter the MAC address of the device you want to repeat (IE 50:23:AB:D4:56:E1).

Q: Why does my Web Smart switch(DGS-1216T) always log me out when moving from page to page or link to link?

A: Please ensure that you are using Internet Explorer 6.0.x or higher when configuring D-Link Web Smart switches, as other browsers or earlier versions of IE may cause some minor problems. You will not be logged out of your switch when using Internet Explorer 6.0.x or higher.

Q: Why are my ping request slower when using D-Link Web SMART Switches?

A: Since the Web Smart switches are not as robust in features as fully managed switches, they have a slower CPU. Therefore, depending on what process Web Smart switch is currently running, the ping response time will be varied and longer.

Q: What is a Combo Port on an Ethernet Switch?

A: A Gigabit Ethernet Combo port is an Ethernet port and a Mini-GBIC port (also called SFP´s) that share the same switch fabric and port number. A Combo port is a way to provide different types of connectivity without taking up unused switch fabric. These Combo ports can also be labeled as tied, meaning two different physical ports that can only be used one at a time. A Gigabit Ethernet Combo port consists of one 1000Base-T Gigabit over Copper port (provided), and one Mini-GBIC port (empty port that requires Mini-GBIC module).

Q: Why can´t I share my Internet connection to multiple computers when using my D-Link switch or hub?

A: If you are connecting directly to a Cable or DSL modem, you will need a router to share your Internet connection or a computer using ICS (Internet Connection Sharing) or Proxy. Switches and hubs do not allow you to share a single IP address to multiple computers.

Another alternative is to contact your ISP and purchase extra IP addresses for each additional computer.
