Tutorial: how to create a personal VPN server based on Linux Debian, strongSwan, certificates authentification and ready to use .mobileconfig profiles to use on iPhone, iPad and Mac

This is a part of a big article I posted on Medium. Here is only a tutorial.

We're going to create a personal VPN server, using the following technologies:

• IKEv2 as a VPN protocol
• Linux Debian as a server OS
• strongSwan as a VPN server
• Certificates as an authentication method

You can use this tutorial on any hosting you prefer.

    let regex = try? NSRegularExpression(pattern: pattern, options: [])
    let range = NSRange(location: 0, length: count)
    return regex?.stringByReplacingMatches(in: self, options: [], range: range, withTemplate: "$1_$2").lowercased()
  }
