Port Forward Fortnite: How to Open Ports on Routers Behind CGNAT  

Fortnite is a survival and third-person shooter game centered around the player in the middle of a scenario. Tactical games like Fortnite require you to open ports on your router to maintain stable connections. 

Some games can play exceptionally better when you open ports on your router. Although some routers are not designed to allow incoming traffic, this guide covers how you can open ports for Fortnite, even if it is behind CGNAT. 

What is Port Forwarding? 

Port forwarding is a networking method that allows you to direct incoming traffic to a specific device or application. Opening ports can help connect to remote devices, view CCTV camera feeds, run a website, or reduce connectivity issues. 

Before You Forward a Port 

You need to know the following before opening ports for any game and application: 

• The IP address of your router 
• The IP address of your device (computer or console)
• Port numbers (UDP and TCP)

How to Port Forward Fortnite Manually 

Follow the steps below: 

1. Log in to your router.
2. Navigate to the port forwarding section. 
3. Enter the IP address of your gaming device in the relevant section. 
4. Enter TCP and UDP numbers where it’s required. 
5. Reboot the router to implement the changes. 

How to Open Ports on Routers Automatically Behind CGNAT

Most routers are behind CGNAT (Carrier-Grade NAT), which prevents any user from opening ports on a router. However, you can still port forward routers behind CGNAT using PureVPN’s port forwarding add-on and dedicated IP. Here’s how: 

1. Login to the PureVPN member area.
2. Click the subscription tab.
3. Click Configure.
4. Apply your desired port settings.
5. Click Apply settings.

Why is Opening Ports behind CGNAT an Issue? 

Most ISPs (internet service providers) perform CGNAT to prevent IPV4 exhaustion and network congestion. This practice has been common among top ISPs in significant countries. But due to CGNAT, you can’t open ports on our routers for gaming and remote access. 

Even if you try to port forward on routers somehow, chances are your IP address can get blacklisted and banned. This is where PureVPN’s port forwarding add-on and dedicated IP comes in for the rescue. 

In Summary

This guide ensures you open the correct ports without risk or hassle. All you have to do is use PureVPN’s port forwarding add-on and dedicated IP address to automatically open ports on multiple routers at home, including Spectrum, Infinity, and Starlink.
