How to Forward Ports in a Siemens Gigaset SE105 Router

Siemens GigasetSE105 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 Gigaset SE105 router.
  3. Navigate to the port forwarding section.
    • Click the Advanced Setup link.
    • Click the NAT link.
    • Click the Virutal Server link.
  4. Create a port forward entry.

While these steps might seem difficult at first, we will walk you through each step for your Siemens GigasetSE105 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.

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 GigasetSE105 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 Siemens GigasetSE105 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:

Siemens GigasetSE105

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

  • The Default Siemens Gigaset SE105 Router Username is: blank
  • The Default Siemens Gigaset SE105 Router Password is: blank

Enter your username and password, and then click the Login button to log in to your Siemens GigasetSE105 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 GigasetSE105 router username and password, use our How to Reset a Router Password guide to set your Siemens GigasetSE105 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 GigasetSE105

Click the Advanced Setup link near the center of the page.

Siemens GigasetSE105

Click the NAT link near the left of the page.

Siemens GigasetSE105

Click the Virutal Server link near the left of the page.

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:

Enter the IP address that you want to forward these ports to into the Private IP box. Note that if you are forwarding ports so you can run a program on a device other than your computer then you can enter your device's IP address into that box instead.

Put the same port number into both the Private Port and the Public Port boxes.

Choose the protocol that you are forwarding from the Type radio button.

In this router if you need both TCP and UDP forwarded then you need to create a duplicate configuration. One of the configurations has TCP selected and the other one has UDP selected.

Most people will never need to use this, but I'm going to explain why they have Private Port and Public Port here.

The Private Port and Public Port entries are actually rather useful. They are there so you can direct traffic at two devices on your network.

Let's say that you have two devices running Ftp servers on your network. Let's call these devices device one(192.168.2.1) and device two(192.168.2.1).

Let's also say both these ftp servers are running on port 21. Okay we setup your router to forward port 21 to device one(192.168.2.1:21).

So every external IP address request from ftp goes to device one. How do we get to the second device? Well the Private Port and Public Port entries allow us to specify another outside port to connect to our internal port 21. Lets make the additional port, port 30. We would now setup a rule in the router with the Public Port set to 30 and the Private port set to 21. The IP address in that rule would be 192.168.2.1. So when you wanted to ftp to device two you would specify port 30 in your ftp client.

The router would see these requests coming in on port 30 and forward them to (192.168.2.1:21). This would allow you to ftp to both devices.

When you're finished, click Apply near the bottom of the screen to save your changes.

Test if Your Ports are Open

Now that you have forwarded ports on the Siemens GigasetSE105 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.
