We support 4 different types of VPN, we generally recommend trying the VPNs in the order they are listed below; OpenVPN is our recommended method.
In a censored country?
If you're in a censored country please use OpenVPN with the 'DPI' options for best performance; OpenVPN DPI is an option at install/set-up time.
Stealth can also be used from censored countries, although OpenVPN DPI will usually perform best without sacrificing encryption strength.
If you have problems with OpenVPN DPI, then try Stealth as a secondary option. Stealth is available for computers only, due to the additional software requirements.
Those familiar with 'side loading' may prefer the ADB method, ADB is probably for the 'techies' amongst you, everyone else will probably find the 'Downloader' method easier
Build your own VPN router using virtualisation software (VMware, Parallels, Virtualbox, etc) and LEDE/OpenWRT, running on a host computer/laptop.
Build your own VPN router using a Raspberry Pi 3 and LEDE/OpenWRT (earlier versions not supported), this will work as an appliance connected to your existing routers ethernet/cabled ports.
