ZeroTier One

ZeroTier One for iOS allows you to join ZeroTier virtual networks as VPN connections on your iPhone, iPad, or iPod Touch.

ZeroTier creates peer to peer virtual Ethernet networks that work anywhere. It's used as a faster alternative to VPNs, to provide a seamless hybrid or multi-site/multi-provider cloud backplane, for remote collaboration and distributed teams, and for Internet of Things (IoT) applications to provide direct end-to-end connectivity to specialized devices.

See https://www.zerotier.com/ for more information.

This app provides virtual network endpoint functionality for iOS devices. To join a virtual network from an iOS device, simply tap the '+' button, enter the network ID and name, and click Join Network! (Once a network is added you can also join it via the iOS VPN control panel. It will appear there as an available VPN connection.)

You can only join one ZeroTier network at once due to an iOS limitation of one VPN connection per network extension app. The app allows you to add multiple networks but if you flip one to 'on' any others currently joined will disconnect.

If you encounter any bugs or serious issues please e-mail support@zerotier.com for help and we'll try to fix them as soon as we can!
