CGNAT Setup Recommendations


Carrier-grade NAT (CGNAT, also known as large-scale NAT), is a method of sharing a single unique public IP address with multiple services to allow providers to extend their pool of usable IPv4 addresses. This means your modem or router will be assigned a private IP address instead of a unique public IP address. Your ISP will then translate that into a shared public address allowing you to access the Internet. Because of this shared address it can often cause issues with your setup.

What we recommend if your on a CGNAT is to change the Transport Type to TCP and the Registration Length to be equal or less than 5 minutes (300 seconds).

If you have a device that doesn't let you change the transport type, such as a Fritzbox, keep it set to UDP but change the
Registration Length to be equal or less than 1 minutes (60 seconds).

If you continue to experience issues please feel free to contact our Customer Support Team.
