好了，都配置完了，下面我们做个测试。。。
我本机的IP地址为172.16.0.2/24，为了测试我在ISA防火墙策略里添加了一条关于ICMP的策略。。
在我本机ping 172.16.0.5，结果：
C:\Documents and Settings\beckham~23>ping 172.16.0.5
<?XML:NAMESPACE PREFIX = O />

Pinging 172.16.0.5 with 32 bytes of data:

可以ping通，然后ping 192.168.0.1
C:\Documents and Settings\beckham~23>ping 192.168.0.1

Pinging 192.168.0.1 with 32 bytes of data:

呵呵，当然不会通了。。。
下面我在本机上又新建了一个网络连接（建立×××连接就不用我教了吧？不会的可以到网上找找），我已经建好了，记得在属性---安全里面×××类型选择PPTP，如图15
