Question
How do I configure port forwarding on my SBG6580?
Answer

NOTE 1: This document applies to software version SBG6580-3.5.8.1-GA-01-477-NOSH and later.

NOTE 2: For assistance in determining the firmware version, refer to answer # 22214 - SBG6580: Locating the Software Version.

Port Forwarding allows the option to run a publicly accessible server on the LAN by specifying the mapping of TCP / UDP ports to a local device.  This enables incoming requests on specific port numbers to reach devices such as Web Servers, Mail Servers, and Digital Video Recorders (DVR).

This document contains the following sections:

  • Creating and Enabling Port Forwarding Entry
  • Disabling Port Forwarding Entry

NOTE 1: It is recommended to manually configure the TCP / IP settings on the server that will be remotely accessible.  If this is done, then it is mandatory to configure the following settings:

  • IP address
  • Subnet mask
  • Default gateway
  • At least one DNS address


If the following settings are configured without the default gateway, remote access to the server will not be available, as it will only be accessible from the local network.

NOTE 2: When manually configuring the TCP / IP settings on a device, make sure that the DHCP pool in the SBG6580 doesn't include the IP address of the server.  To verify or to adjust the DHCP pool, please refer to Answer # 20838 - SBG6580: LAN Options Setup.

NOTE 3: If the firewall is set to High or Medium, port forwarding feature will be inoperable.  The firewall needs to be set to Low to function.


Creating and Enabling Port Forwarding Entry

  1. Launch a web browser, such as Internet Explorer, Firefox, or Safari. Enter http://192.168.0.1 into the address box.

    NOTE: By default the LAN IP address is 192.168.0.1.  If the default address has been changed, enter the custom address in the address box.

  2. Enter admin in the Username field.
  3. Enter motorola in the Password field.
  4. Click the Login button. The Status page appears.

  5. Click the Advanced link on top of the screen.
  6. Click the Forwarding button in the left-hand menu.
  7. In the Port Forwarding menu:
    a.   Internal
          I.    IP Address - Enter the IP address of the server.
          II.   Start Port - Enter the desired port number. 
          III.  End port - Re-enter the desired port number.
         
          NOTE: If it is desired to forward a range of ports, enter the first number of the range for Start Port, and the last number of the range for End Port.

    b.   External
          I.    Remote Host Address - Leave at 0.0.0.0.  This will allow incoming traffic on the specified ports from any remote IP address.  This is sufficient for most setups.

          NOTE:  If it is desired to allow incoming traffic on the specified ports from only one remote IP address, enter that IP address for the Remote Host Address.
           
          II.   Start Port - Enter the desired port number. 
          III.  End port - Re-enter the desired port number.


          NOTE: If it is desired to forward a range of ports, enter the first number of the range for Start Port, and the last number of the range for End Port.


    c.   Protocol - Click on the drop-down menu and select the appropriate protocol (TCP, UDP, or Both).
    d.   Enabled - Click this checkbox to enable the gateway to forward the ports entered in this entry.
     
  8. Click the Apply button.

    NOTE: The example below shows two port forwarding entries: One for a single port (407), and the other for a range of ports (1417-1420).
