Broken docs on setting up exit VPN node

[tian2992]

Hello, i was researching on the topic, found the docs at https://docs.zerotier.com/exitnode/ and while "enough" weren't acceptable for my usecase, specifically ipv6 routing. I went on to research on history and found.

ecde02a#diff-cf89d22ba248ef2a3963d6c318b323cf49d2a077c100c4598d6e01a564ca7717

While from a nerdy point of view it really butchered it, I can see how it became more accessible to noobies and significantly shortened in scope.
However I'd like to ask for permission from @joseph-henry before going around and reworking it a bit, saving some of the best bits from the original. I would like to comply to contributors guidelines and help create a nice overview of what can it be done.

Please let me know on suggestions and places to improve as I suggest a PR :)
Thanks!

Thanks for your interest! I thought I had updated the v6 section... It's actually still an open PR that I forgot to push through.

That information was written probably 7 years ago. Let us know if there's some better way to do it!

Ok that's merged. It's probably not on the website for a little bit.
