Sweex LB000021 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 Sweex LB000021 router.
- Navigate to the port forwarding section.
- Click the General Setup button.
- Click the NAT link.
- Click on Virtual Server or Port Forwarding.
- Create a port forward entry.
While these steps might seem difficult at first, we will walk you through each step for your Sweex LB000021 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 Sweex LB000021 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:

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:
Forwarding a Single Port
Enter the IP address that you want to forward these ports to in the Private IP box. You can enter either the IP address of your computer or the IP address of another computer or device on your network.
Enter the same port number to be forwarded into the Private Port and the Public Port boxes.
The protocol that you want to forward is selected from the Type box.
You need to name this entry in the Comment 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.
Click the Add button when you are finished.
Forwarding a Port Range
Enter the IP address to forward these ports to into the Private IP box. 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.
From the Type box select the protocol for the ports that you want to forward.
If you are only forwarding a single port number then enter that number into both the Left Port Range and the Right Port Range boxes. If you are forwarding a range of ports separated by a hyphen then enter the lowest number of that range into the Left Port Range box and the highest number of that range into the Right Port Range box.
Create a name for this forward and put it in the box. The name is only used as a reminder and has no effect on the port forward.
Click the Add button when you are finished.
Your ports should now be open. It is time to test them.
