Your CT Systems FWRIII-3105SFP-CW-N-DR router protects your home network by limiting incoming connections from the internet. Sometimes it is necessary to unblock some of those connections like when you want to create a direct connection for gaming, use a specific application, or set up a new device on your network. This process is called forwarding or opening a port. In your CT Systems FWRIII-3105SFP-CW-N-DR router you many need to open a port, which means assigning a port number or set of port numbers to a specific IP address. This routes the incoming data to the correct device on your network.

To open a port in your CT Systems FWRIII-3105SFP-CW-N-DR router, follow these important steps:

  1. Go ahead and set up a static IP address on the computer or device that you are forwarding these ports to.
  2. Go ahead and log in to your CT Systems FWRIII-3105SFP-CW-N-DR router.
  3. Make your way to the Port Forwarding section of the CT Systems FWRIII-3105SFP-CW-N-DR router.

Step 1

If you want to ensure that your ports remain open even after your device reboots, set up a static IP address in the device that you are opening a port for.

After setting up a static ip address on your devices you need to login to your router.

Step 2

Log in to the CT Systems FWRIII-3105SFP-CW-N-DR router. To do this you need to use a web browser because the CT Systems FWRIII-3105SFP-CW-N-DR router uses what is called a web interface.

It normally doesn't matter what web browser you use so go ahead and open up your favorite. If you don't have a favorite then open up Chrome, Firefox, or Edge.

If that is confusing to you, we have simplified this step with this link: Login to your FWRIII-3105SFP-CW-N-DR Router

Once you have opened up a browser window, find the address bar. This is usually at the top of the page like the image below shows.

Step 4

Opening a port to a specific device may solve problems that you are having on your network. Make sure that it is necessary though, before opening a port, because you are effectively creating a pinhole in the firewall portion of your router that could lead to malicious traffic on your network. The risk is exceedingly low, though, so don't let this warning stop you from making this change if you need it.

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:

  1. Put a check in the box named Enable.

  2. If you are forwarding a single port number, enter it into the Public Port box. If you are forwarding a range of ports, enter the lowest number of that range into the Public Port box, followed by a hyphen followed by the largest number. For example, a range of port numbers might look like this: 1000-2000.

  3. In the Protocol dropdown box, select the protocol type of the ports you are forwarding. Choose Both if your router has that option. Otherwise, choose either TCP or UDP as needed. If you need to forward a port for both TCP and UDP and your router does not have the Both option, then you need to create two entries.

  4. You need to enter the IP address that you are forwarding ports to into the LAN IP box. This can be either the IP address of your computer or any other IP address on your network that you want ports forwarded to.

  5. Take the values that you entered in the Public Port box and put the exact same numbers in the Local Port box.

  6. Create a name for this forward and type it into the Application Description box. Since the name does not have an effect on the functionality of the forward, choose a name that will help you remember why the forward was created.

  7. Click the Apply button to apply these changes when you are completely finished.
