US Robotics USR9110 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 US Robotics USR9110 router.
- Navigate to the port forwarding section.
- Click the NAT link.
- Click the Virtual Server link.
- Create a port forward entry.
While these steps might seem difficult at first, we will walk you through each step for your US Robotics USR9110 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 US Robotics USR9110 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 US Robotics USR9110 IP Address is: 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:
You should see a box prompting you for your username and password.
- The Default US Robotics USR9110 Router Username is: admin
- The Default US Robotics USR9110 Router Password is: 1234
Enter your username and password, and then click the Login button to log in to your US Robotics USR9110 router.
US Robotics Usernames and Passwords
If your username and password do not work then please visit our Default US Robotics Router Passwords page.
If you still can't login to your router because you forgot your US Robotics USR9110 router username and password, use our How to Reset a Router Password guide to set your US Robotics USR9110 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 NAT link near the left of the page.
Click the Virtual Server link near the left of the page.
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 LAN IP Address box. This is either the IP address of a computer or the IP address of another device on your network.
Select the required protocol for these ports from the Protocol Type dropdown box.
Put the same port number into both the LAN Port and the Public Port boxes.
Verify that you have the Enable checkbox checked.
Click the Add button when you are done.
Most people will never need to use this, but I'm going to explain why they have Lan Port and Public Port here.
The Lan 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 Lan 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.
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 US Robotics USR9110 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.
