What is it?
Alternative Tailscale coordination server, which can be self-hosted.
How and why I use it
I use Tailscale to connect my devices to my LAN, which runs different services. Some of these services are available only locally to increase security of the whole setup. It also allows each device to use AdGuardHome DNS.
My setup
I have Headscale running on a VPS to not reveal my IP.
Tailscale uses DERP servers to traverse NAT. I only use the internal one, because I don’t need to cover a vast network of devices. If the need would ever arise, I’d spin up additional VPS.
Authentication
Right now, I manually add new devices to correct user accounts.
In future, I’d like to make use of Authentik to provide OIDC login.
