How to get OpenVPN details from macOS to iOS I have a VPN which I connect to on my MacBook with Tunnelblick. I would like to setup my iPhone 6 to connect to the same VPN, however I am struggling to find an app or way to do this.

In Tunnelblick, I can see the configuration file which looks like this:

dev tun
proto udp
remote vpn.crmpicco.co.uk 1194
cipher AES-128-CBC
auth SHA1
resolv-retry infinite
nobind
persist-key
persist-tun
client
verb 3
auth-user-pass
&lt;ca&gt;
 [Security-related line(s) omitted]
&lt;/ca&gt;
&lt;cert&gt;
 [Security-related line(s) omitted]
&lt;/cert&gt;

&lt;key&gt;

&lt;/key&gt;


Can anyone advise me on how to connect to this VPN on iOS?
Assuming I understand your question correctly, you can use iTunes on the MacBook to transfer the profile you're using into OpenVPN on your iPhone.

Broadly speaking, you need to:


Download and install the OpenVPN app from the app store onto your iPhone
Locate the OpenVPN config file (it should have a .ovpn extension) you downloaded on your MacBook so you know where it is
Connect your iPhone to your MacBook
Launch iTunes
Select your iPhone (within iTunes)
Click on Apps on the left-hand menu
Scroll to the bottom in the main window (on the right-hand side) and click on the OpenVPN icon in the Apps box 
Drag and drop the OpenVPN config file (the one you located at Step 2) into the OpenVPN Documents box
Click on Done
Open the OpenVPN app on your iPhone
You should now see the new certificate listed
Click on the green + sign
Enter your username, password etc
Tap on the Save toggle


Now when you want to connect to the VPN from your iPhone, just tap on the toggle that appears below the Disconnected label. You should be connected shortly thereafter.
