Have you tried using ZeroTier? I don‘t have much experience using Tailscale but have been using ZeroTier for two years now without any problems. Runs great on Synology
I use a selfhosted public DNS which runs AdGuard Home where I have multiple block lists running that filter my whole Internet Access from Home, which not only makes my internet at home a lot faster because Ads and other annoying or malicious sites don‘t even get loaded/sent to my home network, but makes it also safer. I run it on a VPS since I have my parents and friends use it too.
I mean it’s a start and the fine is for possession outside the home, but it will also be removed when full legalisation is in place.
