Apple iOS devices (iPhone, iPad, and iPod Touch) and macOS 10.6 and higher devices include a native Cisco IPSec VPN client. You can use this client to make an IPSec VPN connection to a Firebox. To use the native IPSec VPN client to make a connection to your Firebox, you must configure the VPN settings on your Firebox to match those on the iOS or macOS device.

DNS Resolver Selection in iOS 14 and macOS 11. Apple announced the release of iOS 14 on Sept 16, 2020. Among other changes, iOS 14 and macOS 11 include support for encrypted DNS, and the ability for domain owners to designate a DNS resolver of their choosing. This change has a direct effect on the ability of OpenDNS to resolve some domain names. Check your DNS server settings. System Preferences - Network - Advanced - DNS. Hopefully you have a good DNS server. Since you are using the University's VPN, in theory you need to use a DNS server provided by the University so that servers on the University's LAN are listed. Using a public DNS server could be used, but it would only lookup.

For IPSec VPN connections from a macOS device, you can also use the WatchGuard IPSec VPN Client for macOS. For more information, see Install the IPSec Mobile VPN Client Software.

You must configure Mobile VPN with IPSec for default-route VPN (0.0.0.0/0). The VPN client on the macOS or iOS device does not support split tunneling.

Supported Phase 1 and 2 Settings

For devices with iOS 9.3 and higher or macOS 10.11.4 and higher, these combinations of Phase 1 and 2 settings are supported.

If Diffie-Hellman Group 14 is selected in the Phase 1 settings:

  • Phase 1 Authentication — MD5, SHA1, SHA2-256, SHA2-512
  • Phase 1 Encryption — AES256
  • Phase 2 Authentication — MD5, SHA1
  • Phase 2 Encryption — 3DES, AES128, AES256
  • Perfect Forward Secrecy — No

If Diffie-Hellman Group 2 is selected in the Phase 1 settings:

  • Phase 1 Authentication — MD5, SHA1
  • Phase 1 Encryption — DES, 3DES, AES128, AES256
  • Phase 2 Authentication — SHA1, MD5
  • Phase 2 Encryption — 3DES, AES128, AES256
  • Phase 2 PFS — No

For devices with versions of iOS lower than 9.3, these Phase 1 and 2 settings are supported.

  • Diffie-Hellman Group 2
  • Phase 1 Authentication — MD5 , SHA1
  • Phase 1 Encryption — DES, 3DES, AES128, AES256
  • Phase 2 Authentication — MD5 , SHA1
  • Phase 2 Encryption — 3DES, AES128, AES256
  • Phase 2 PFS — No

Diffie-Hellman Group 5 is not supported on Apple devices for aggressive mode. Mobile VPN with IPSec only supports aggressive mode.

Configure the Firebox

Many of the VPN tunnel configuration settings in the VPN client on the macOS or iOS device are not configurable by the user. It is very important to configure the settings on your Firebox to match the settings required by the VPN client on the macOS or iOS device.

To configure the Firebox, from Fireware Web UI:
  1. (Fireware v12.3 or higher) Select VPN > Mobile VPN.
  2. In the IPSec section, select Configure.
    The Mobile VPN with IPSec page appears.

    The Mobile VPN with IPSec Settings page appears.
  1. In the Name text box, type the name of the authentication group your macOS or iOS VPN users belong to.

You can type the name of an existing group, or the name for a new Mobile VPN group. Make sure the name is unique among VPN group names, as well as all interface and VPN tunnel names.

  1. From the Authentication Server drop-down list, select an authentication server.

You can authenticate users to the Firebox (Firebox-DB) or to a RADIUS, VASCO, SecurID, LDAP, or Active Directory server. Make sure that the method of authentication you select is enabled.

If you create a Mobile VPN user group that authenticates to an external authentication server, make sure you create a group on the server with the same name you specified in the wizard for the Mobile VPN group. If you use Active Directory as your authentication server, the users must belong to an Active Directory security group with the same name as the group name you configure for Mobile VPN with IPSec. For more information, see Configure the External Authentication Server.
