The ZeroTier network hypervisor is a self-contained network virtualization engine that implements an Ethernet virtualization layer similar to VXLAN built atop a cryptographically secure global peer-to-peer network. It provides advanced network virtualization and management capabilities on par with an enterprise SDN switch, but across both local and wide area networks and connecting almost any kind of app or device.
MikroTik has added ZeroTier to RouterOS v7.1rc2 as a separate package for the ARM/ARM64 architecture.
By default, ZeroTier is designed to be zero-configuration. A user can start a new ZeroTier node without having to write configuration files or provide the IP addresses of other nodes. It’s also designed to be fast. Any two devices in the world should be able to locate each other and communicate almost instantly so the following example will enable ZeroTier on RouterOS device and connect one mobile phone using the ZeroTier application.
Enable the default (official) ZeroTier instance:
Add a new network, specifying the network ID you created in the ZeroTier cloud console:
Now you might need to allow connections from the ZeroTier interface to your router, and optionally, to your other LAN interfaces:
Verify ZeroTier configuration:
You should specify routes to specific internal subnets in the ZeroTier cloud console, to make sure you can access those networks when connecting from other devices.
