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:
- Setup a static IP address on either your computer or device that you want to forward a port to.
- Login to your Siemens 4100 router.
- Navigate to the port forwarding section.
- Click the Setup link.
- Click on Port Forwarding.
- 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.
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 Static IP Setter will set up a static IP address for you.
- Another way to get a permanent IP address is to set up a DHCP reservation.
- Or, manually create a static ip address with our Static IP Guides.
This step is important because you want a permanent IP address in your device. If you do not set up a permanent IP address in your device, then when you device reboots it may get a new IP address.
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:
Above is an example of what a web browser address bar looks like. Find the address bar in your router and type in your router's IP address.
The default Siemens 4100 IP Address is: 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:
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.
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:
Click the Setup link near the left of the page.
You should now see a new menu. In this new menu, click Port Forwarding.
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.
