Read full description

This is an iOS client to help you connect to a Nebula network (a popular open-sourced Github project with name slackhq/nebula). To use this app, you will need to create your own Nebula server (lighthouse) on a cloud instance (AWS, Azure, Google Compute Platform, DigitalOcean, etc.) or a router (OpenWrt) or a computer. Also supports on-demand rules for specific domains to automatically start the connection. This app guides you on every single step on setting up a lighthouse server, connecting your iOS device to the Nebula network, and setting up Nebula on other types of devices. The guides cover from editing configuration file, downloading bundle, generating certificate, setting up unsecured routes and more. Nebula is a tool to connect machines across different networks. For example, you can use it to connect to your cloud instances, your home NAS, office networks, home printers and many other types of devices (or even an entire private subnet) securely and remotely anywhere in the world. It is a meshed network which can connect any devices around the world (even behind NAT, with the help of at least one lighthouse server). This app offers setup guides not only for iOS devices, but also the lighthouse server, on router OpenWrt, and Linux systems. It can be easily used by both beginners and experts who are already using the Nebula network. For professional users, you can also set a DNS over HTTPS and DNS over TLS. Also, you can configure whether to use UDP punch.
