Why Opening Ports Behind CGNAT is an Issue? 

Many ISPs (internet service providers) perform CGNAT (Carrier-Grade NAT) to save IPv4 addresses by sharing one public IP among multiple users who are connected to the same network as you are. Unfortunately, you can’t open ports on your router behind CGNAT because your IP address can get blacklisted or blocked.
