Cradlepoint CTR350 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 Cradlepoint CTR350 router.
- Navigate to the port forwarding section.
- Click the Advanced link.
- Click on Gaming.
- Create a port forward entry.
While these steps might seem difficult at first, we will walk you through each step for your Cradlepoint CTR350 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 Cradlepoint CTR350 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:

Click the Advanced link near the top of the page.
The menu on the left should change. In this new menu, click Gaming.

- UDP Ports: 3074
If you are looking for the ports for a different application you can find it by either:
Put a checkmark in the Enable checkbox.
Put a name for this forward in the 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.
Enter the IP address of the device that you want to forward ports to into the IP Address box. This can be either the IP address of your computer or the IP address of another device on your network.
Enter the ports to forward into the TCP Ports to Open and UDP Ports to Open box.
The ports can be entered as a list 23,24,25, a range 500-600, or a combination of both 23,45,500-600.
Choose Allow All from the Inbound Filter dropdown box.
Use the Schedule dropdown box to choose Always.
When you are done click the Save button.
When you're finished, click Save Settings near the top of the screen to save your changes.
