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 (192.168.0.1).

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.

di-624a

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.

You must open ports on your router to allow incoming traffic while using eMule.

eMule uses three ports*:

  • 4662 (TCP)
  • 4672 (UDP)
  • 4711 (TCP)
  • * To prevent getting a low ID (Firewalled), open additional TCP ports between 4661 and 4665. Also, limit the number of connections in the eMule software. You may need to change the TCP Clientport to something other than 4662.

    1.For the DI-5xx, DI-6xx, DI-704P (revC), DI-704UP, DI-754, DI-764, DI-774, DI-784, DI-804HV, DI-808HV, and DI-824VUP:

    Step 1: Open your web browser and enter the IP address of your router (192.168.0.1). Enter username (admin) and your password (leave blank).

    Step 2: Click on Advanced and then click Virtual Server.

    Step 3: Create a new entry:

  • Click Enabled.
  • Enter a name (emule1).
  • Private IP – Enter the IP address of the computer you are running eMule from.
  • Select TCP for Protocol Type
  • Enter 4662 for both Private Port and Public Port
  • Click Always or set a schedule.
  • Step 4: Click Apply and then Continue.

    Step 5: Repeat steps 3 and 4 but name it emule2, select UDP for Protocol Type, and enter 4672 for both Private Port and Public Port.

    Step 6: Repeat steps 3 and 4 but name it emule3, select TCP for Protocol Type, and enter 4711 for both Private Port and Public Port.

    Note: If the screenshots look different (DI-604), then you have the European version of your router which D-Link USA does not support.

    2.For the DI-704P (revA), DI-704, DI-707, DI-711, DI-713, and DI-713P:

    Step 1 Open your web browser and enter the IP address of the router (192.168.0.1). Enter user name (admin) and your password (blank by default). If there is only 1 box, enter admin.

    Step 2 Click on Advanced at the bottom and then click Virtual Server.

    Step 3 Create a new entry:

    • Enter 4661-4665 in the box under Service Ports.
    • Enter the IP address of the computer you want to run eMule from.
    • Check the box under Enable.
    • In the next box down, enter 4672 under Service Ports.
    • Enter the IP address of the computer you want to run eMule from.
    • Check the box under Enable.
    • In the next box down, enter 4711 under Service Ports.
    • Enter the IP address of the computer you want to run eMule from.
    • Check the box under Enable.

    Step 4: Click Save and the click Reboot.

    NOTE: If you can only enter a single port (not a range) and/or are limited to 10 entries, upgrade your firmware to the latest version at support.dlink.com/downloads.

    According to a account by D-Link, firmware updates for its DIR-635 (HW-Revision B), DIR-655 (HW-Revision A1-A4) and DIR-855 (HW-Revision A2) router models are now accessible to download to abutting the recently discovered hole in the Home Network Administration Protocol (HNAP) of these devices.

     

    D-Link say they have also discovered issues with the discontinued DIR-615 (HW-Revision B1-B3), DI-634M (HW-Revision B1) and DIR-635 (HW-Revision A) models. A firmware update for the DIR-615 has been released, with updates for the DI-653-M and DIR-635 to follow in the coming weeks.

     

    The updated firmware is available from www.dlink.de currently and will be available on the www.dlink.co.uk site within the next few days.

     

    Last week, the SourceSec website reported that, aside from offering regular administrator access, the DI-524, DIR-628, DIR-655 and potentially further D-Link router models have a permanent HNAP connection which can be exploited by attackers.

     

    According to a statement (german language link) from D-Link Germany, the router models DI-304, DI-524, DI-604, DI-624, DI-724GU, DI-804HV, DIR-100, DIR-300, DIR-301, DIR-320, DIR-600, DIR-615, DIR-685, DIR-825, DSL-2543B, DSL-2641B, DSL-2740B, DSL-2741B, DVA-G3342SD and DVA-G3342SB are not affected because they either don’t use HNAP or testing showed this protocol wasn’t accessible.

     

    UpdateFirmware updates for the DIR-615, DIR-635, DIR-655 and DIR-855 routers are now available from the UK D-Link site.
