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. 

First Time Configuration

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.

  1. Register on and create your network, obtain the Network ID XXXXXXXXX;
  2. Download and Install ZeroTier NPK package in RouterOS;
  3. Enable the default (official) ZeroTier instance:

    [admin@mikrotik] > zerotier/enable zt1

  4. Add a new network, specifying the network ID you created in the ZeroTier cloud console:

    [admin@mikrotik] zerotier/interface/add network=8286ac0e473d**** instance=zt1

    If an "Access Control" is configured in the "Private" state, then you have to allow RouterOS authorization under Networks "members" section.

  5. Now you might need to allow connections from the ZeroTier interface to your router, and optionally, to your other LAN interfaces: 

    [admin@mikrotik] /ip firewall filter> add action=accept chain=forward in-interface=zerotier1 place-before=0
    [admin@mikrotik] /ip firewall filter> add action=accept chain=input in-interface=zerotier1 place-before=0

  6. Verify ZeroTier configuration:

    [admin@MikroTik] > zerotier/interface/print
    Flags: R - RUNNING
    #   NAME       MAC-ADDRESS        NETWORK           NETWORK-NAME  STATUS
    0 R zerotier1  2A:DD:A1:4C:5C:C9  8286ac0e473d**** testme_mt     OK 

  7. Install a ZeroTier client on your smartphone or computer, follow the ZeroTier manual on how to connect to the same network from there. 

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.
