Should I use UPnP?

Should You Disable UPnP? Ultimately, it is a matter of opinion. UPnP is convenient but does bring with it some quite serious security flaws, some of which cannot be mitigated by security solutions. It's our recommendation that if you don't use port forwarding at all, then you should disable UPnP.

Does Verizon use CGNAT?

ISPs like Verizon FiOS, who want to keep using their current IPV4 infrastructure and provide services to the customers using the IPV6 protocol, can use CGNAT to allow multiple users on an IPv4 network to do so and share a single public IP address.
