Chapter 4 Authentication : Users and user groups : User groups : Firewall user groups : SSL VPN access
  
SSL VPN access
SSL VPN interface settings include a list of the firewall user groups that can access the SSL VPN and the SSL VPN portal that each group will use. When the user connects to the FortiGate unit via HTTPS on the SSL VPN port (default 10443), the FortiGate unit requests a username and password.
SSL VPN access also requires a security policy where the destination is the SSL interface. For more information, see the FortiOS Handbook SSL VPN chapter.
