So I managed to install ZeroTier with the Ubiquiti Edge Router X via:
admin@edgerouter# sudo -i root@edgerouter:~# curl -s https://install.zerotier.com | sudo bash
And got to access the Edge OS (Edge Max) interface through the ZeroTier Global IP, so I can access my router anywhere in the world which is great.
However, how can I access the LAN devices connected to the router? For example, I have one device with Local IP in the router,
How can I access this using the ZeroTier network?
