Fastest Siemens 4100 Router Open Port Guide

Siemens 4100 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 Siemens 4100 router.
  3. Navigate to the port forwarding section.
    • Click the Setup link.
    • Click on Port Forwarding.
  4. Create a port forward entry.

While these steps might seem difficult at first, we will walk you through each step for your Siemens 4100 router.



We think that forwarding a port should be easy. That's why we created Network Utilities. Our software does everything that you need to forward a port.

Get Started Now!

When you use Network Utilities you get your port forwarded right now!

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 Siemens 4100 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:


10.0.0.138

In the picture above the address bar has 10.0.0.138 in it. Just replace all of that with the IP address of your Siemens 4100 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: 10.0.0.138

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

Siemens 4100

You should see a box prompting you for your username and password.

  • The Default Siemens 4100 Router Username is: admin
  • The Default Siemens 4100 Router Password is: admin

Enter your username and password, and then click the Login button to log in to your Siemens 4100 router.

Siemens Usernames and Passwords

If your username and password do not work then please visit our Default Siemens Router Passwords page.

If you still can't login to your router because you forgot your Siemens 4100 router username and password, use our How to Reset a Router Password guide to set your Siemens 4100 router back to its factory settings.

Step 3

Now we need to find the port forwarding section in your router. Here's how you do it. Starting from the first page in your router:

Siemens 4100

Click the Setup link near the left of the page.

You should now see a new menu. In this new menu, click Port Forwarding.

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:

In the Select protocol box select the protocol that you want to forward these ports over.

If you are just forwarding a single port number then you can simply enter that same number into both the Left TCP/UDP port(s) and the Right TCP/UDP port(s) boxes. If you are forwarding a range of ports, usually separated by a hyphen, then you need to enter the lowest number of that range into the Left TCP/UDP port(s) box and then enter highest number into the Right TCP/UDP port(s) box.

Make sure that the Redirect select protocol/service to IP Address radio button is selected.

Enter the IP address that you are forwarding ports to in the Redirect select protocol/service to IP Address box. This is either the IP address of a computer or the IP address of another device on your network.

When you are all done click the Apply button.

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

Test if Your Ports are Open

Now that you have forwarded ports on the Siemens 4100 you should test to see if your ports are forwarded correctly.

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.
