    多年以后再回过头来看Direct Access，发现真的是个好主意，现在win 8也支持了。。微软好样的。

    如果兼容硬件VPN,就可以不用某某公司卖1000多元人民币一个客户端许可的IPSec 客户端软件了，当然，前提是你要买WIN7，还要买2008作为网关操作系统。。。。

    目前的vpn客户端软件价格确实太高，不过可以选择pptp连接啊。那样可以用windows自带的客户端了。

    若使用这种方法，是否只有microsoft自己的win7 或者2008 r2才能使用driect access，能否与其他设备或者软件兼容？是否公开了详细的技术内容？不会跟microsoft windows一样吧。 是否是凭借这个功能，又增强microsoft软件的垄断性。

    VPN软件可以使用Cisco System VPN client或者Fortinet的 Forticlient，如果只有升级到Windows7或者2008才能使用direct access，那不如购买付费的VPN软件呢。

    windows7加人域后。可以正常上网。内外都可以访问。但自定义ip后就仅限访问域内了。解析外网也没问题。但就是上不了外网。打不开网页。这是为什么啊？谢谢老师解答一下。

    你的域内有DHCP吧，这个时候你手动指定IP了，能够解析外网域名，那DNS没有问题，上不了网那就是网关问题了。是否也手动指定网关了呢？
