Tailscale raises $100M

For anyone else who wonders wtf tailscale is:

> Tailscale is a VPN service that makes the devices and applications you own accessible anywhere in the world, securely and effortlessly. It enables encrypted point-to-point connections using the open source WireGuard protocol, which means only devices on your private network can communicate with each other.

It seems to take care of key distribution, nat-traversal, authentication etc etc

Neat! No sure how that is 'fixing internet' exactly, but really cool anyway

Tailscale is one of the ways you can restore the end-to-end connectivity principle that IP introduced and that NAT destroyed.

This is kind of overstated. Even if everyone went IPv6 and gave every device a public IP address, pretty much every network would have a firewall that behaved just like NAT.

Yeah, no one is going to allow unsolicited inbound connections even without NAT so you still have to have something to hook up the two ends in a P2P setting.

Sure they are. All home routers that I'm aware of allow for port forwarding so folks can self-host a service: perhaps a game server (e.g., Minecraft), web, e-mail, etc.

It's just going forward you can set up a separate subnet to put your gear in (especially if you get multiple /64 subnets from your ISP). You can have a DMZ, and use either the router- and/or host-level firewall to dictate which connections are allowed.

... if your definition of "home routers" excludes ISP-provided ones, then I'll agree. Unfortunately, I'm pretty sure that either you are on an ISP that actually cared and found a good supplier or didn't check out what are the capabilities of ISP-provided routers.
