Nexian RE-251 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 Nexian RE-251 router.
  3. Navigate to the port forwarding section.
    • Click the Firewall 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 Nexian RE-251 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.

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 Nexian RE-251 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 Nexian RE-251 IP Address is: 10.165.25.43

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.

Enter your username and password, and then click the Login button to log in to your Nexian RE-251 router.

Nexian Usernames and Passwords

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

If you still can't login to your router because you forgot your Nexian RE-251 router username and password, use our How to Reset a Router Password guide to set your Nexian RE-251 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:

Click the Firewall 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:

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

If you are forwarding a single port then you can enter that port number into the left Port Range and the right Port Range boxes. If you are forwarding a range of ports, enter the lowest number of that range into the left Port Range box. Then enter the highest number of that range into the right Port Range box.

From the Protocol box select the protocol for the ports that you want to forward.

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.

After you are 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 Nexian RE-251 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.
