I'm on a relatively large Indian ISP, and my home network gets an IPv6 network assigned, which is directly routable. Didn't think about it until tailscale told me it was connecting over a direct IPv6 connection and I wondered how that was possible. Sounds like 90s network rampage may be back here.

Well yes, natting is not normal on ipv6 - that’s a major feature.

Direct connections are a good thing and how the Internet is supposed to work. NAT is the only reason IPv4 has lasted this long.

Blocking inbound connections using connection tracking is orthogonal to NAT. It's just that NAT implies the former by default due to its nature.
