It is possible to connect an modern Apple Mac with OSX to a FireBrick over IPSEC with IKEv2 and EAP.

It is possible to connect an Apple Mac with OSX to a FireBrick over IPSEC with IKEv2 and EAP. Regrettably the IPSEC facilities within OSX before version 'El Capitan' are not fully enough featured to achieve this alone, so some additional VPN client software can be installed called StrongSwan. Details below describe how to install the CA certificate from the FireBrick to your Apple computer and then how to set up the VPN connection either by using El Capitan's built in VPN settings or by using StronSwan.

=OSX versions 10.11 El Capitan, and newer=

⚫

== Getting the CA from the FireBrick ==

*If you have El Capitan newer, then the built in VPN connection settings should just work.

*If you're not using Let's Encrypt then you will still need to install the Certificate as below.

*You can skip the StrongSwan parts below and just use the Network Settings to add a VPN IKEv2 connection.

===Create the VPN Connection===

Note: this guide doesn't go into actual configuration of the FireBrick to be an endpoint, merely how to connect your Mac client to it. Therefore it is assumed the certificate already exists on the FireBrick. It may also be that this is emailed to you by whoever maintains your FireBrick, in which case skip this step.

#*Remote ID: The 'FQDN' of the Firebrick as created when you created the Certificate (Usually the full hostname of the FireBrick). e.g.: server.example.com

⚫

#*Local ID - leave empty

== Downloading & installing the StrongSwan Native Client ==

Visit [http://download.strongswan.org/osx/ the download site] and download the latest binary. At the time of writing the latest version was '''strongswan-5.3.2-1.app.zip'''. Allow the machine to unarchive it; usually by selecting the "Open with Archive Utility" option. This will deposit the StrongSwan.app into your downloads directory. Drag the app from the downloads directory into your Applications folder. This completes installation of the StrongSwan Client.
