Again, we agree. :)

Again, agree. Packet filtering is only one function that a firewall can perform, as you point out. Either way, it's not NAT. NAT has a different purpose - rewriting IP addresses to achieve some networking goal (most commonly share a single public IP among multiple hosts).

Looks like it. :(

Mine's been in service for years. I occasionally tweak it when I change something on the LAN, last tweak was to put the HAMnet router as the IPv4 exposed host, so IP-IP encapsulation works.

MvV> I loved that sketch! ;-)
Yes! I haven't seen it for many years.
