Go to VPN.
Tap on Add VPN network option.
On this step (or any further steps) you may be asked to create a lock screen PIN-code or password to use a credential storage. This is needed to save your VPN login and password, so you don't have to enter them every time.
Configuration screen should look like this.
Click on the PPTP under Type option.
This will open a list of possible connection types.
Choose L2TP/IPSec PSK from the list.
Enter StrongVPN as Name.
Fill full Server Address to Server address field. (Your server is not "vpn-xxx.reliablehosting.com", it is just an example. You can find your Server Address in the Customer Area, check this tutorial to see how to do it.)
Input your IPSec pre-shared key (you should get it in your setup instructions email or available from customer area) to IPSec pre-shared key.
You can find it in the Customer Area (check this page).
Check Show advanced options.
Under DNS servers enter 188.8.131.52.
Now you should see StrongVPN connection in the list. Tap on it.
Authorization window will appear. Enter your Username (it should be like: vpn042, for example) and Password (both are case sensitive). Select Save account information.
Hint: Username and Password also can be found in the Customer Area (check here to see how to do it).
Press Connect button.
When the VPN is connected the key icon should appear at the top bar. Also the StrongVPN status in the connections list should change to Connected.
Done. You are connected.
