I've been a fan of Tailscale since encountering it for the first time at a previous job at a small startup. Someone asked if anyone had a Linux machine when we were all testing out something, and I mentioned I had a personal Linux desktop but wasn't sure how to connect it to the VPN for access, and it turned out that the solution was just literally running two commands in the terminal after installing tailscale from the repos. Compared to my first job where connecting to the VPN from Linux required hours of mucking around with openswan (or was it strongswan? so many swans...) and trial and error with various config files, it was unfathomably straightforward.
