    这是一个创建于 3875 天前的主题,其中的信息可能已经有所发展或是发生改变。
    如题,我搜到的方法没有一个有用的……所以求助各位V大神了

    配置:

    option /etc/ppp/pptpd-options
    name pptpd
    refuse-pap
    refuse-chap
    refuse-mschap
    require-mschap-v2
    # Require MPPE 128-bit encryption
    # (note that MPPE requires the use of MSCHAP-V2 during authentication)
    require-mppe-128
    # }}}
    mppe-stateful
    s-dns 8.8.8.8
    ms-dns 8.8.4.4

    # If pppd is acting as a server for Microsoft Windows or "Samba"
    # clients, this option allows pppd to supply one or two WINS (Windows
    # Internet Name Services) server addresses to the clients. The first
    # instance of this option specifies the primary WINS address; the
    # second instance (if given) specifies the secondary WINS address.
    ms-wins 127.0.0.1
    proxyarp

    # Debian: do not replace the default route
    nodefaultroute


    # Logging

    # Enable connection debugging facilities.
    # (see your syslog configuration for where pppd sends to)
    debug

    # Print out all the option values which have been set.
    # (often requested by mailing list to verify options)
    #dump


    # Miscellaneous

    # Create a UUCP-style lock file for the pseudo-tty to ensure exclusive
    # access.
    lock

    # Disable BSD-Compress compression
    nobsdcomp
    nopcomp
    noaccomp

    remoteip 192.168.0.100-200

    我用google compute engine搭pptpd遇到了同样的问题,怀疑是googole的路由设备对GRE支持有问题

    谷歌官方回复不支持GRE转发的,所以PPTP不行,浪费了好多时间。。。
    可以使用L2TP或者是OPENVPN,softether也行的。
