Step 1: Download OpenVPN Connect from the AppStore to your iPhone/iPad... View In iTunes
Step 2: Open the Settings app on your iPhone/iPad. Click on VPN and delete all profiles, if any. Not doing this will cause an error later on. If you don't see the VPN section, then click General->VPN.
Now, you will leave this setup guide to download the OpenVPN "Config-File" you will use. After that, return back to this setup guide.
Log into the tigerVPN Dashboard and navigate and on the right hand side you will see "OpenVPN". Hit "download" to get the config files.
Drag that config files to your desktop. Now, return back to the iPhone/iPad setup guide for OpenVPN (256bit) and go to step 5.
Plug your iPhone/iPad into your computer and open iTunes. Click on the "Apps" tab under your iPhone/iPad in iTunes. Scroll down to the "File Sharing" section.
Click on the OpenVPN app.
Locate the config file you downloaded earlier to your desktop. It should be named "config-256bit". Un-zip the archive. Locate the new "config" folder and open it. Drag the ovpn file(s) and certificate file to the OpenVPN app in iTunes.
Open the OpenVPN Connect app on your iPhone/iPad. You will see new profiles available. Click the green plus(+) button to add your new profile(s) to the app. NOTE: If the app crashes upon launch, then go to the Settings app and delete any VPN profiles there.
Enter your tigerVPN username and password.
Slide the switch to turn on the vpn.
You are now connected to tigerVPN using OpenVPN on your iPhone/iPad.
NOTE: To turn the vpn on/off, you must go to this app to do so. Do not turn the vpn on/off in the settings app because that will cause a connection error.
