Unfortunately, port forwarding is not possible using a CGNAT (Carrier-Grade Network Address Translation) IP address. CGNAT is used to conserve IPv4 addresses by sharing a single public IP address among multiple customers.
To port forward, you may specifically request to opt out of CGNAT, which you may agree to at our discretion. When opting out of CGNAT, a dynamic Public IP address will be assigned to the service, however, at a cost of $5 monthly on top of your service plan.
You may also request a Static IP address for $11 monthly.
