It seems to be more like a reverse proxy that integrates with ZeroTier.
In the GitHub it's mentioned the the Zoraxy is compatible with ZeroTier but due to licensing issues, ZeroTier is not included in the binary.
Just wondering is there any legit open source alternative for ZeroTier?
Judging by the features, it doesn’t seem predominantly focused on routing and acting as a tool or server you can deploy to operate a network and allow other devices to leverage it to route between networks.
