League of Legends is an exciting and fast-paced multiplayer online battle arena (MOBA) game where players compete in strategic team battles. To ensure you have stable connections, it’s important to know how to open ports for League of Legends behind CGNAT. Follow our guide to learn how you can port forward your routers (Spectrum, Xfinity, Starlink) and maintain stable connections. 

What is Port Forwarding? 

Port forwarding is a networking method that directs incoming traffic to specific devices on your private network by opening ports on your router. It’s essential for gamers who are connected to private servers for games like League of Legends or Call of Duty, to enable port forwarding for stable gameplay and server connections.

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)

Default Ports for League of Legends 

To optimize the performance of League of Legends, you need to open specific ports on your router. These ports are:

For PC

  • TCP: 2099, 5222-5223, 8088, 8393-8400

Why Opening Ports Behind CGNAT is an Issue?  

CGNAT is a networking technique that saves IPv4 addresses by assigning multiple users a single public IP address. Most ISPs perform CGNAT to prevent IPv4 exhaustion and network congestion. However, if you want to open ports on a router, chances are your IP address can be blocked or blacklisted.
