Before diving into the thick of the troubleshooting, it is important to understand that your
Internet Service Provider (ISP) and the way you
share the connection speed play a huge role in how you experience the game.
To try and improve your overall connection to the game and its features, please try the below steps in the order listed:
• Enable UPnP
Please contact your ISP for additional information and help with enabling this feature.
Below are the ports you need for Rainbow Six: Siege:
TCP: 13000, 13005, 13200, 14000, 14001, 14008, 14020, 14021, 14022, 14023, 14024
UDP: 6015
This step will also help you establish an Open
NAT for your connection with the game.
