Vista系统无法进行L2TP VPN远程连接 RRS feed

    各位好!

    我在防火墙上建立了一个VPN远程访问,是基于L2TP协议的,在Windows XP系统新建一个VPN连接时可以顺利通过;

    但使用Vista系统建立一个VPN连接时发生失败,错误提示如下:

    ID:789
    L2TP 连接尝试失败,因为安全层在初始化与远程计算机的协商时遇到一个处理错误。

    MS的解释是:

    内容如下:

    CAUSE
    This behavior occurs because of changes in Windows Vista that help improve security.

    When the Cisco ASA Series VPN server performs a L2TP/IPsec negotiation, the server uses the message ID to identify the client. This negotiation is a phase 2 quick-mode negotiation. However, in a quick-mode negotiation, all Windows Vista-based VPN clients use the same message ID for their initial messages. Therefore, when a Windows Vista-based VPN client connects to a VPN server, message IDs from other Windows Vista-based VPN clients are considered duplicate IDs. Therefore, the VPN server refuses the other connections.

    也没有提出好的解决之道。。。

    欢迎大家参与讨论。
