MikroTik
MikroTik maintains a ZeroTier package for their line of networking products.
Choosing a model
For best performance it is recommended that you choose a model that has a 64-bit ARM chip (arm64). Not 32-bit ARM. 32-bit ARM devices will work but with significantly reduced performance. Currently no MIPS ZeroTier package exists for MikroTik devices.
If you're an enterprise-sized entity looking to integrate MikroTik + ZeroTier we'd recommend getting some guidance from IP ArchiTechs who are very familiar with the performance characteristics of various models and can help design a solution for you.
Troubleshooting
Since MikroTik developed and maintains the ZeroTier package themselves you may need to search or ask questions on their forum if you need additional help please come visit our forum and we'll try to help.
If you're new to ZeroTier we'd recommend reading our Getting Started Guide.
