/Techsupport side note. I have a Windows laptop, and for the life of it the client will not connect to the service. How do I troubleshoot this thing? Its almost too simple. Are there logs? https://i.imgur.com/QRLkQl1.png
/And is there any way to get to test the magic dns? Will there be better ways to set up relay nodes, and then SEE the design of the network? Can I set up a relay node on Windows, and only for specific IP addresses instead of entire subnets?
/On the topic of "security within the lan is just a nuisance" I do appreciate this being more of a unix philosophy like single tool than kitchen sink. I do think there would be a market for a companion piece of cloud software that acts as a firewall orchestrator between devices, surfaces logs, allows you to block or allow specific connections between specific devices, and to visualize the activity of the mesh. It would be beneficial to be able to super quickly design a "all the field ipads can get to the server, but not each other" type network, while at the same time giving pcs more LAN like access, or being able to designate "edge/guests/clients" that can only connect to "servers." The two types of networks shouldnt need to be mutually exclusive.
/On the topic of other markets and use cases, and maybe this isnt what Tailscale ever wants to be, I think there is a huge opportunity for a pure software client Wireguard SD-WAN a la Velocloud. If I have two ISPs plugged into my network, let me define BOTH gateways as acceptable places for traffic outflow, and build simultaneous tunnels out both. Maybe load balance traffic between them, watch for packet loss, congestion, jitter, and correct accordingly. That extra redundancy of being able to lose a link and keep the path would be extraordinary.
