For each camera that resides behind a router or gateway, three ports must be forwarded by the router to obtain both audio and video. If audio is not desired, only the HTTP port will need to be forwarded. The three default ports are as follows:

  • 80 (TCP) HTTP Port (allows access to web-configuration and transmits video if other ports are not forwarded)
  • 5002 (TCP/UDP) Audio Channel Port (transmits synchronized audio)
  • 5003 (TCP/UDP) Video Channel Port (transmits synchronized video)

These port numbers will need to be changed in the camera configuration on each additional camera that is added behind the router. Port numbers can be changed from the Advanced > Network screen.


Practical Example:

Three DCS-6620s are behind a D-Link DI-604. The router has a public IP address (WAN) of and an internal (LAN) IP address of

Camera 1 IP address: Ports: 80, 5002 and 5003
Camera 2 IP address: Ports: 81, 6002 and 6003
Camera 3 IP address: Ports: 82, 7002 and 7003

Each set of three ports must be forwarded to the respective IP address. Set-up for Camera 1 inside a DI-604s configuration is shown below:


This will need to be done for each camera and their respective ports.

To contact these cameras from a remote location (across the Internet), use the Public IP address (WAN) of the router along with the appropriate web port. Using the above example:

To remotely contact camera 1 with Internet Explorer, enter
To remotely contact camera 2 with Internet Explorer, enter
To remotely contact camera 3 with Internet Explorer, enter

These cameras can also be contacted remotely with IP surveillance (included software).

Step 1 Launch the Monitor application and choose Function Menu > Camera Configurations.

Step 2 Enter the routers Public IP address and port number in the IP address field in the top left corner.

Step 3 Click the Insert button directly above.

Step 4 Click Save.

MAC Address Control

This D-Link DI-704P provides two features in MAC Address Control: Fixed IP Mapping and Connection Control. Both these features are MAC level. You can enable these features by checking the “Enable” box.

Fixed IP Mapping

This feature let you assign the MAC address and IP address mappings. Each client in the “Control table” will get the IP address mapping to its MAC address. If you don´t want to assign a fixed IP to a specific client, please leave the IP address blank.

Connection control

Connection control allows you to allow or deny the clients to connect to this DI-704P and the Internet. Check “Connection control” to enable the controlling. If a client is denied to connect to this device, it means that the client can´t access the Internet and some network resources . Choose “allow” or “deny” to allow or deny clients whose MAC addresses are not listed in the “Control table”.

When a client CAN “Connect” to this D-Link DI-704P, it means that it can have full access to the Internet and network resources.
When a client CAN NOT “Connect” to this device, it means that it CAN:
Communicate with the other clients on the LAN
●Connect to the Internet
●Use the Print Server function
●Use the Web configuration

Control table

“Control table” is at the bottom of the “MAC Address Control” page. Each row of this table indicates the MAC address and the mapped IP address of a client. The columns in this table are:

    MAC Address Indicates a specific client´s MAC address.
    IP Address Expected IP address of the corresponding client. Leave it blank if you don´t want to assign a specified IP address to the corresponding client.
    C When “Connection control” is enabled, checking “C” will allow the corresponding client to “Connect” to this device.

Previous page, Next page

To make this setup page simple and clear, we have divided the “Control table” into several pages. You can use these buttons to navigate to different pages.


    Item Setting
    MAC Address Control Enable
    Connection control Clients with C checked can connect to this device; and
    unspecified MAC addresses to connect.
    ID MAC Address IP Address C
    1 192.168.50.
    2 192.168.50.
    3 192.168.50.
    4 192.168.50.


In this scenario, there are two clients listed in the Control Table.
The “MAC Address Control” function is enabled.

“Connection control” is enabled, and all of the clients not listed in the “Control table” are “allowed” to connect to this device.
Client 1 has a fixed IP address either from the DHCP server of this device or manually assigned:
ID 1 – “00-12-34-56-78-90” –>
Client 2 will obtain its IP address from the IP Address pool specified in the “DHCP Server” page or can use a manually assigned static IP address.

If, for example, client 1 tries to use an IP address different from the address listed in the Control table (, it will be denied to connect to this device.

Clients 2 and other clients with a MAC address unspecified in the Control table are all allowed to connect to this device. But client 1 is denied to connect to D-Link DI-704P.

Note: Please configure the DSA-3100 with the computer that was last connected directly to the modem. Also, you can only use the Ethernet port on your modem. If you were using the USB connection before using the DSA-3100, then you must turn off your modem, disconnect the USB cable and connect an Ethernet cable to the WAN port on the DSA-3100, and then turn the modem back on. In some cases, you may need to call your ISP to change connection types (USB to Ethernet).

Step 1: Connect the Ethernet cable from your modem into the WAN port on the back of the D-Link DSA-3100.

Step 2: Open a web browser and enter the IP address of the DSA-3100 in the address bar (default is Be sure to include https:// followed by the IP address. Press Enter.

Step 3: The default username is admin (all lower case) and the default password is admin (all lower case). Click OK.

Step 4: Click the Home tab and then click WAN on the left.

Step 5: Select your connection type using the radio buttons.
Static IP Address – If your ISP issued you a static IP address, choose this option and enter the IP address, subnet mask, and default gateway.


Dynamic IP Address – If you connect to the Internet without having to authenticate with a username and password, then choose this option.


PPPoE Client – If you connect to your DSL connection using a PPPoE connection, then choose this option. Be sure to enter your username and password. Contact your ISP if you are unsure of what to enter. Choose Enabled using the radio buttons next to Dial on demand. Enter a value next to Maximum Idle Time if you want your connection to terminate after x minutes of inactivity.


Step 6: Click Apply and then click Restart to apply the new settings.
