Pretty neat that you don't use NAT. I had a public IP on my laptop
once(ONCE) & the Chinese kept sending garbage to any port that was open
& it made my laptop hot(almost burned my thighs!) What's your secret to
avoid this??

As I'm sure you're aware, iptables & nftables allow you to configure
NAT for IPv6. I couldn't seem to find any useful critisisms of NAT for IPv6.

IPv4 isn't going anywhere anytime soon & I doubt any commercial
enterprise will write software soley for publicly-addressable, consumer
PCs.
