Engine Editor > VPN > VPN Client VPN Type Defines the type of tunnels the mobile VPN supports.
  • IPsec VPN — The mobile VPN only supports IPsec tunnels.
  • SSL VPN — The mobile VPN only supports SSL VPN tunnels.
  • Both IPsec & SSL VPN — The mobile VPN supports IPsec and SSL VPN tunnels.
SSL Port (SSL VPN types only) The port for SSL VPN tunnels.
TLS Cryptography Suite Set (SSL VPN types only) The cryptographic suite for SSL VPN tunnels.
Authentication Timeout (SSL VPN types only) The timeout for Stonesoft VPN Client user authentication.
Local Security Checks Defines whether Stonesoft VPN Client checks for the presence of basic security software to stop connections from risky computers.
Virtual IP address (Using Virtual Adapter)

Use PFS with Diffie-Hellman Group Diffie-Hellman group used in IKE SA negotiations when PFS can be used.
VPN Profile element properties > IPsec Client tab Authentication Method The selected authentication method used with Stonesoft VPN Client.
Allow Hybrid/EAP Authentication Stonesoft VPN Client users authenticate by user name and password (or other type of passcode), and the gateway authenticates itself to the client with a certificate.
Allow CN authentication Allows authentication using the common name in the certificate as the user name. The CN is checked against a value entered in the User elements.
Allow Pre-Shared Key Authentication with IKEv1 This setting has no effect on Stonesoft VPN Client connections, as pre-shared key authentication is not supported.
IPsec Security Association Granularity Defines whether SAs are negotiated per network or per each connecting IP address.

Stonesoft VPN Client only supports the SA Per Net setting.

Policy-Based VPN element > Tunnels tab Pre-shared Key fields This setting has no effect on Stonesoft VPN Client connections. Pre-shared keys for Stonesoft VPN Client connections are defined per-user account in the User elements.
