@sutt359 A CGNAT is a Carrier Grade Network Address Translation. Your home router has NAT (network address translation).  NAT is a method of sharing one public IP address with all computers behind it.  That's how you're able to use several devices and computers in your home network with only one IP from your ISP. Well, that how it was for you when you had a public IP address previously.  NATs are also the basic building block quite often for a firewall.  You don't get past the public IP address
