Consider the following scenario:

  • You have a computer that is running Windows Vista or Windows Server 2008.
  • You create a new incoming connection by using static IP addresses from the static IP address pool.
  • You use only one of the following authentication protocols as the authentication for the incoming connection:
    • Challenge Handshake Authentication Protocol (CHAP)
    • Password Authentication Protocol (PAP)

In this scenario, you cannot start a virtual private network (VPN) connection to this computer from a client computer that is running Windows XP, Windows Server 2003, or Windows Vista.
