Fastest T-Com Speedport W303V Router Open Port Instructions

T-Com Speedport-W303V routers include a very basic firewall that helps protect your home network form unwanted access from the internet. Since this firewall blocks incoming connections you may need open a port through it for certain games and applications. This process of opening a port is frequently called a port forward, since you are forwarding a port from the internet to your home network.

The basic process to open a port is:

  1. Setup a static IP address on either your computer or device that you want to forward a port to.
  2. Login to your T-Com Speedport W303V router.
  3. Navigate to the port forwarding section.
    • Click the Konfiguration starten button.
    • Click the Netzwerk link.
    • Click the NAT & Portregeln link.
    • Click the Port-Weiterleitung link.
    • Click the Neue Regel definieren link.
  4. Create a port forward entry.

While these steps might seem difficult at first, we will walk you through each step for your T-Com Speedport-W303V router.

Step 1

It is important to setup a static ip address in the device that you are forwarding a port to. This ensures that your ports will remain open even after your device reboots.

  • Recommended - Our free program will setup a static IP address for you.
  • Or follow our Static IP Address guides to setup a static IP address.

After setting up a static ip address on your devices you need to login to your router.

Step 2

Now we are going to login to your T-Com Speedport-W303V router. Your router has a web interface, so you will login to it using your web browser. This can be either Chrome, Firefox, Internet Explorer, or Edge. It usually does not matter which browser you choose to use.

Open up your web browser and find the address bar. It should look something like this:


192.168.2.1

In the picture above the address bar has 192.168.2.1 in it. Just replace all of that with the IP address of your T-Com Speedport-W303V router. Your router's IP address can also be refered to as your computer's default gateway.

By default the IP address is set to: 192.168.2.1

After entering the IP address of your router you can simply press enter. If all goes well you will see the following screen:

Step 4

Here are the ports to forward for Xbox Live:

TCP Ports:3074
UDP Ports:3074

If you are looking for the ports for a different application you can find it by either:

You need to name this entry in the Bezeichnung box. The name does not make any difference in the forward; it's just there so that you can remember later why you setup this forward.

In the Aktiv checkbox put a checkmark.

In the Gultig fur Gerat box to choose a device to forward ports to. This box contains a list of device names that are visible on your network.

Put the ports to forward into the TCP and UDP box.

You can enter the ports as a list 23,24,25, a range 500-600, or a combination of both 23,45,500-600.

Click the Speichern button when you are finished.

Your ports should now be open. It is time to test them.

To test if your port has been properly forwarded, you can use our Network Utilities tool, which includes a free Open Port Checker. Our Open Port Check tool is the only online port checking tool with Guaranteed Results.
