Opening Ports in a 2wire 3800HGV-B Router
The 2wire 3800HGV-B router has a very basic firewall that helps protect your network from unwanted Internet access. The firewall works by blocking incoming connections that have not been authorized. In order to create new connections through the firewall you need to create what is called a port forward. This is done for online gaming and other online applications.
- How to setup a static IP address on the device you plan on forwarding these ports to.
- How to login to the 2wire 3800HGV-B router web interface.
- How to find the port forwarding page in the router's web interface.
- How to setup a port forward for the online game or program of your choice.
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!
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.
- → Download Network Utilities today!
- 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.
TIP: Write this static IP address down. You need it in Step 4.
Now we are going to login to your 2wire 3800HGV-B router. Your router has a web interface, so you login to it using a 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 looks something like this:
In the image above I have circled the address bar for you. All you need to do is replace what is currently in the address bar with the router's IP address. The router's IP address is also called the computer's default gateway.
By default the IP address is set to: 192.168.1.254
IF you have set up an administrator password in the past, you will be shown an authentication page like this:
Enter the administrator password you created in the past. If you have forgotten you can use our Find Password App to help you.
IF you have not setup an administrator password you will be shown the Network at a Glance page:
IF you are not shown any kind of router interface screen or a login screen, you need to find out if the router's IP address is correct. To do this follow our How To Find Your Router's IP Address guide.
It is now time to find the port forwarding section of the router interface. To do this we begin on the Network at a Glance page:
Begin by clicking the Firewall option at the top of the page.
Now click the Firewall Settings button below that.
On this page, use the Select a computer drop down box to choose which device you are forwarding these ports to. This is the device you created a static IP address for. This drop down box should contain a list of all the devices that are visible on your network.
Now click the Ad a new user-defined application option.
This takes you to the correct page to make a port forward entry.
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 name of the program into the Application Name box. It doesn't really matter what you put into this box, but something that will remind you why these ports are being forwarded is be a good idea.
Choose the protocol that you are forwarding from the Protocol 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.
If you are just forwarding a single port number then you can simply enter that same number into both the Port (or Range) From and the Port (or Range) To 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 Port (or Range) From box and then enter highest number into the Port (or Range) To box.
Enter the protocol timeout into the Protocol Timeout (seconds) box. The protocol timeout should be set to 86400 if you are using the TCP protocol, or 600 for the UDP protocol.
You can leave the Map to Host Port box empty.
You can leave Application Type set to None.
Click the Add Definition button.
Click the Back button.
Now select the port forwards you just created in the Applications list and click the Add button to move them to the Hosted Applications box.
When you are finished, click the Done button in the bottom right corner of the screen.
Test if Your Ports are Open
Now that you have forwarded ports on the 2wire 3800HGV-B 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.
