Configure iOS and macOS Devices for Mobile VPN with IKEv2

You can configure the native IKEv2 VPN client on iOS and macOS devices for a VPN connection to your Firebox.

To automatically add a VPN profile to your device, you can use .mobileconfig profile that you download from the Firebox. Or, you can manually configure the settings. This topic includes instructions for both automatic and manual configuration.

Fireboxes with Fireware v12.1 or higher support Mobile VPN with IKEv2.

For information about which operating systems are compatible with each mobile VPN type, see the Operating System Compatibility list in the Fireware Release Notes. You can find the Release Notes for your version of Fireware OS on the Fireware Release Notes page of the WatchGuard website.

WatchGuard provides interoperability instructions to help our customers configure WatchGuard products to work with products created by other organizations. If you need more information or technical support about configuring a non-WatchGuard product, see the documentation and support resources for that product.

Automatically Configure VPN Settings

To automatically configure a VPN connection with a profile provided by WatchGuard, you must download a .TGZ file from your Firebox and extract the contents. This file contains instructions and profiles for different operating systems. For information about how to download this file, see Configure Client Devices for Mobile VPN with IKEv2.

The profile creates a new IKEv2 VPN connection. It also installs the required CA certificate for the VPN connection.

On iOS devices, you must type the user name and password when prompted. If you do not specify a user name and password, the VPN profile is created but does not work.

  1. Send the .mobileconfig file to your macOS computer.
  2. To import the file, double-click it.
    The Profiles dialog box opens.
  3. When prompted to install the profile, click Continue.
  4. (Optional) To save your username and password for later use, specify those credentials now.
  5. Click Install.
  6. When prompted to install the profile, click Install.
  7. From the Apple menu, select System Preferences > Network.
  8. To connect to the VPN, click the VPN connection that you added and click Connect.
  1. Send the .mobileconfig file to your iOS device.
  2. Open the message in the native iOS mail app and tap the .mobileconfig file.
    A Profile Downloaded message appears.
  3. Tap Settings > General > Profiles.
  4. In the Downloaded Profiles section, tap the profile.
  5. Tap Install > Next > Install > Install.
  6. (Required) Specify the username and password. On iOS devices, if you do not specify credentials in the configuration, the VPN profile exists but fails to connect.
  7. Tap Done.
  8. On the Settings screen, tap VPN.
  9. To connect to the VPN, tap the VPN connection that you added.
  10. Slide the Status toggle to Connecting.

Manually Configure VPN Settings

You can manually add a new VPN connection rather than use the profile provided by WatchGuard.

  1. Send the rootca.crt or rootca.pem file to your macOS computer.
