zerotier

Connect Linux desktops, servers, NAS devices, phones, or individual applications to virtual networks with ZeroTier. Its ZeroTier One service provides network connectivity and lets a device join a virtual network; use zerotier join to connect and zerotier status to view its state.

ZeroTier functions as a software-based managed Ethernet switch rather than relying on a physical LAN or WAN. It can replace VPNs, tunnels, and proxies associated with rigid physical networks, while sending traffic over the most direct peer-to-peer path available.

Connections are encrypted end to end. On Linux, zerotier requires snapd and supports amd64, arm64, armhf, i386, ppc64el, and s390x systems.
