Founder here, yep you're totally right, BitTorrent and this kind of application won't work as there's no outbound NAT. It's on the todo list however.
Bu pretty much everything else works just fine, e.g. hosting docker containers, Webservers, databases..
Cheers Ian
I'm curious, how would you support this usecase?
Your server won't be reachable over IPv4 from the outside, but it'll work to access most IPv4 exclusive services.
Alternatively, simple carrier grade NAT, possibly using 4over6, can also work. You would provide servers with an internal IPv4 address that would get NAT'ed just like on residential homes.
