Back when I had Comcast (and thus native IPv6 at home), this was a great way to expose a web server at home without resorting to either weird port forwarding or setting up a proxy + SNI. Both of those work, but this is super clean. (Now I only have IPv4, so I just use Tunnel).

  Even using something like Hurricane Electric, this is still a nice solution to get access to services hosted on a residential connection. Feels a lot cleaner to me than weird reverse tunnelling solutions.

Are there any plans for SSH tunneling without using cloudflared at the client side? Also: supporting both a SSH and an HTTP tunnel on the same A record would be nice

  We do actually, on our paid plans: https://blog.cloudflare.com/cloudflare-for-ssh-rdp-and-minecraft/ https://blog.cloudflare.com/cloudflare-for-ssh-rdp-and-minec... You get A and AAAA records by default.

Does this end up being similar to say an haproxy doing domain based load balancing to an ipv6 endpoint(s)? I assume you have loads of customers on any single ipv4 IP ingress right?

I'm using Zero Trust Tunnel for some web apps I host in my home, but I'm trying to think if the older service (IPv4 to IPv6) you describe would be useful for anything, like ssh'ing into my home from an external VPS. Would the earlier product be used for something like a router, which can't run the Tunnel service?
