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. > Well, you'll also want ARP for MAC address discovery and ICMP to report > errors. > ... > Also consider the internet connection, you may need to run PPPoE to a > xDSL modem or similar. I hadn't thought to mention this - thank you. - Jeremy
