ZeroTier is an incredibly useful tool to enable true access from anywhere to any networked resource. Although TrueNAS has removed ZeroTier support, the FreeBSD package is easy to install and seems to work fine! The only issue is that it doesn’t persist across reboots without some major risky work.
If you’re like me, you have a lot of different systems running in different places: at work, at home, in the lab, and in the cloud. And if you’re like me you’ve often struggled to connect and access these machines, especially when you’re on the road. At long last, I have a fully functional solution that lets me access everything from everywhere, securely and efficiently, whether on the open internet or behind NAT after NAT. The solution is ZeroTier!
