SUMMARY
The Point-to-Point Protocol (PPP) client software in the current versions of Windows products that support Internet Protocol version 6 (IPv6) does not support sending native IPv6 packets over PPP-based interfaces.



MORE INFORMATION
The PPP clients for Windows Server 2003, for Windows XP, and for Windows CE 4.1 and later do not support the IPv6 Control Protocol (IPv6CP) for sending native IPv6 packets over a PPP-based interface, as described in IETF RFC 2472. For more information, visit the following IETF Web site:

http://www.ietf.org/rfc/rfc2472.txt

However, you can send IPv4-tunnelled IPv6 traffic over a PPP or a PPPoE-based interface, except in the case that is described in the following Knowledge Base article:

836790 You cannot connect to IPv6 destinations by using tunnels over PPP devices

IPv6 is available for local area network (LAN) connections in Windows Server 2003; however, it is not available for the following connection types:
 * Dial-up connections
 * Virtual Private Network (VPN) connections
 * Direct connections
 * PPP over Ethernet connections
