dan@upvote.au 2 days agoI think Tailscale has some methods for hole punching with double NAT (including CGNAT) and symmetric NAT, but it doesn’t work in 100% of cases. tailscale.com/blog/how-nat-traversal-works
IPv6 is definitely a good solution since then you don’t have to deal with NAT at all. IPv6 is pretty easily doable in the USA (at long as you’re not using Starlink) but can be harder in other countries that don’t have as robust IPv6 infrastructure.
