Simple Netopia Cayman3300 Router Port Forwarding
Netopia Cayman3300 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 Netopia Cayman3300 router.
- Navigate to the port forwarding section.
- Click the Expert Mode link.
- Click the Ok button.
- Click the Configure link.
- Click on Advanced.
- Click the Pinholes link.
- Click the Add button.
- Create a port forward entry.
While these steps might seem difficult at first, we will walk you through each step for your Netopia Cayman3300 router.

After setting up a static ip address on your devices you need to login to your router.
Now we are going to login to your Netopia Cayman3300 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:
In the picture above the address bar has 192.168.1.254 in it. Just replace all of that with the IP address of your Netopia Cayman3300 router. Your router's IP address can also be refered to as your computer's default gateway.
By default the IP address is set to: 192.168.1.254
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 Netopia Cayman3300 Router Username is: admin
- The Default Netopia Cayman3300 Router Password is: admin
Enter your username and password, and then click the Login button to log in to your Netopia Cayman3300 router.

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:
Put a name for this forward in the Pinhole Name box so that you can remember why you set this forward up. The name does not matter so pick something that has meaning to you.
In the Protocol Select box select the protocol that you want to forward these ports over.
If you are just forwarding a single port number then you can simply enter that same number into both the Internal Port and the External Port Start 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 Internal Port box and then enter highest number into the External Port Start box.
You need to enter the IP address that you are forwarding ports to in the Internal IP Address box. It's possible for this to be either the IP address of your computer or any other IP address on your network that you want ports forwarded to.
When you are done click the Submit button.
Click the Alert button near the right of the page.
When you're finished, click Save and Restart near the center of the screen to save your changes.
