The firewall security features built into the D-Link DI-624 router prevent users from accessing the video from the D-Link DCS-2120 over the Internet. The router connects to the Internet over a series of numbered ports. The ports normally used by the D-Link DCS-2120 are blocked from access over the Internet. Therefore, these ports need to be made accessible over the Internet. This is accomplished using the Virtual Server function on the DI-624 router. The Virtual Server ports used by the camera must be opened through the router for remote access to your camera. Virtual Server is accessed by clicking on the Advanced tab of the router screen.

Follow these steps to configure your router’s Virtual Server settings:

**In this example, we are using the DI-624. The Virtual Server interface may differ depending on your router*.

Follow these steps to configure the Virtual Server settings of the D-Link DI-624:

Step 1: Open a web browser such as Internet Explorer and enter the IP address of your router ( Enter username (admin) and your password (leave blank).

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

Step 3: Click Enabled.

Step 4: Enter a different name for each entry.

Step 5: Enter your camera’s local IP Address Private IP field.

Step 6: Select TCP for HTTP port and both (TCP and UDP) for RTSP port.

Step 7: If you are using the default camera port settings, enter 80 into the Public and Private Port section, click Apply.

Step 8: Scheduling should be set to Always so that the camera images can be accessed at any time.

Repeat the above steps adding the port 554 to both the Public and Private Port sections. A check mark appearing before the entry name will indicate that the ports are enabled.

Important: Some ISPs block access to port 80 and other commonly used Internet ports to conserve bandwidth. Check with your ISP so that you can open the appropriate ports accordingly. If your ISP does not pass traffic on port 80, you will need to change the port the camera uses from 80 to something else, such as 800. Not all routers are the same, so refer to your user manual for specific instructions on how to open ports.

Enter valid ports in the Virtual Server section of your router. Please make sure to check the box next to the D-Link camera name on the Virtual Server List to enable your settings.

My D-Link router DI-624 locked up,Follow these steps to solve the problem:

• A large amount of traffic may lock the router up. Disable any broadcast protocols or unused protocols such as NetBEUI and IPX/SPX.

• Disable UPnP(TM) if not being used on both your computer (ME or XP) and on the router (Tools – Misc).

• Check the log on your router. Is it showing a large amount of traffic? If coming from 1 IP address, you may want to use the IP Filter to block that user.

• Check the log settings and uncheck some of the items the router will report.

• Check your firewall and virtual server settings on the router. Too many may degrade performance of the router.

• Upgrade firmware. If you have the latest version, flash it again.

• Perform a hard reset on the router and reconfigure. With the unit powered on, use a paperclip and hold down the reset button for 10-15 seconds. Release and wait about 20 seconds. DO NOT power off while holding the reset button.

Some applications require multiple connections, such as Internet gaming, video conferencing, Internet telephony, VPNs, and others. These applications have difficulties working through NAT (Network Address Translation). If you need to run applications that require multiple connections, specify the port normally associated with an application in the Trigger Port field, select the protocol type as TCP (Transmission Control Protocol, UDP (User Datagram Protocol), or both, then enter the public ports associated with the trigger port to open them for inbound traffic.

This article tell you how to use the special applications feature on D-Link routers,DI-624 as an example.

The Trigger port is an outgoing port (from LAN to WAN) that the application will send out.

Step 1: Open your web browser and enter the IP address of your router (

Step 2: Enter your username (admin) and password, if any.

Step 3: Click on Advanced tab on the top and then Applications on the left side.


Name – This is the name referencing the special application.

Trigger Port – This is the port used to trigger the application. It can be either a single port or a range of ports.

Trigger Type – This is the protocol used to trigger the special application.

Public Port – This is the port number on the WAN side that will be used to access the application. You may define a single port or a range of ports. You can use a comma to add multiple ports or port ranges.

Public Type – This is the protocol used for the special application.

At the bottom of the screen, there are already defined well-known special applications. To use them, click on the edit icon and enable the service.

This FAQ is for the DI-514, DI-524, DI-604, DI-614+, DI-624, DI-624S, DI-754, DI-764, DI-774, and DI-784 routers.

Nortel Contivity will work with the your D-Link router, however its functionality depends on the authentication type (AH will not work), NAT compatibilty mode, and disabling keep alives on the server. Contact your Network Administrator to find out how your VPN is configured.

Step 1: Verify that you are using the latest version of firmware on your router.

Step 2: Login to the Web Management for your router by entering its IP address ( in your web browser. The default username is admin, and the password is blank.

Step 3: Click the Advanced Tab to access the Virtual Server Settings. There is a list of pre-defined Virtual Server Rules towards the bottom of the page. Find the IPSec Rule. Click the pen and paper icon to edit its settings. Enable the rule, enter the IP address of the computer attempting to connect to the VPN in the Private IP field, then Apply the changes.


Step 4: Create a new Virtual Server entry. Name the Virtual Server, “NortelVPN“. Enter the IP address of the computer attempting to connect to the VPN in the Private IP field. For the Protocol Type, select Both. Enter 9550 for both the Public and Private Ports. Set the Schedule to always, then Apply the settings.


Step 5: Access the Tools Page, then click the Misc button. Disable IPSec Pass-through, then click Apply.


If the VPN Server is properly configured to work with clients behind NAT routers you should be able to connect to the VPN.
