3、测试LAN2到LAN1的连通性
我们在位于LAN2的Client1上进行测试,Ping位于LAN1的Server1,并访问运行在其之上的FTP服务。 /* 在Client1上进行测试*/ C:\Documents and Settings\xx>ipconfig Windows IP Configuration Ethernet adapter Loopback: Connection-specific DNS Suffix . : IP Address. . . . . . . . . . . . : 192.168.2.8 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 192.168.2.1 /* Ping自己的网关(ISA防火墙的LAN2接口)*/ C:\Documents and Settings\xx>ping 192.168.2.1 -n 2 Pinging 192.168.2.1 with 32 bytes of data: Reply from 192.168.2.1: bytes=32 time=6ms TTL=128 Reply from 192.168.2.1: bytes=32 time<1ms TTL=128 Ping statistics for 192.168.2.1: Packets: Sent = 2, Received = 2, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 0ms, Maximum = 6ms, Average = 3ms /* Ping ISA防火墙的LAN1接口*/ C:\Documents and Settings\xx>ping 192.168.0.254 -n 2 Pinging 192.168.0.254 with 3 2 bytes of data: Reply from 192.168.0.254: bytes=32 time=1ms TTL=128 Reply from 192.168.0.254: bytes=32 time<1ms TTL=128 Ping statistics for 192.168.0.254: Packets: Sent = 2, Received = 2, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 0ms, Maximum = 1ms, Average = 0ms /* Ping LAN1中的Server1*/ C:\Documents and Settings\xx>ping 192.168.0.1 -n 2 Pinging 192.168.0.1 with 32 bytes of data: Reply from 192.168.0.1: bytes=32 time=2ms TTL=127 Reply from 192.168.0.1: bytes=32 time<1ms TTL=127 Ping statistics for 192.168.0.1: Packets: Sent = 2, Received = 2, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 0ms, Maximum = 2ms, Average = 1ms /*访问Server1上的ftp服务*/ C:\Documents and Settings\xx>ftp 192.168.0.1 Connected to 192.168.0.1. 220 External ftp server ready...

登录/注册后可看大图
注意看客户的IP地址,这是ISA防火墙的LAN1接口的IP。Why?不需要我回答吧。 Okay,这个测试就成功结束了。
4、配置内部到外部使用路由方式
现在我们来修改网络规则,配置内部到外部使用路由方式试试。 点开配置下的网络,在右边的网络规则中双击Internet访问,然后在弹出的属性对话框中,点击网络关系标签,修改为路由。修改后如下图所示:

然后点击应用保存修改和更新防火墙策略。
5、测试LAN2到LAN1的连通性二
/* 在Client1上进行测试*/ C:\Documents and Settings\xx>ipconfig Windows IP Configuration Ethernet adapter Loopback: Connection-specific DNS Suffix . : IP Address. . . . . . . . . . . . : 192.168.2.8 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 192.168.2.1 /* Ping自己的网关(ISA防火墙的LAN2接口)*/ C:\Documents and Settings\xx>ping 192.168.2.1 -n 2 Pinging 192.168.2.1 with 32 bytes of data: Reply from 192.168.2.1: bytes=32 time=6ms TTL=128 Reply from 192.168.2.1: bytes=32 time<1ms TTL=128 Ping statistics for 192.168.2.1: Packets: Sent = 2, Received = 2, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 0ms, Maximum = 6ms, Average = 3ms /* Ping ISA防火墙的LAN1接口*/ C:\Documents and Settings\xx>ping 192.168.0.254 -n 2 Pinging 192.168.0.254 with 32 bytes of data: Reply from 192.168.0.254: bytes=32 time=1ms TTL=128 Reply from 192.168.0.254: bytes=32 time<1ms TTL=128 Ping statistics for 192.168.0.254: Packets: Sent = 2, Received = 2, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 0ms, Maximum = 1ms, Average = 0ms /* Ping LAN1中的Server1*/ C:\Documents and Settings\xx>ping 192.168.0.1 -n 2 Pinging 192.168.0.1 with 32 bytes of data: Request timed out. Request timed out. Ping statistics for 192.168.0.1: Packets: Sent = 2, Received = 0, Lost = 2 (100% loss), Ping不通了?Why?相信你应该可以从上面的TCP/IP配置说明中分析出这一点。 我们再在LAN1中的Server1上进行测试: /* 在Server1上进行测试*/ C:\Documents and Settings\Administrator>ipconfig /all Windows IP Configuration Host Name . . . . . . . . . . . . : Sydney Primary Dns Suffix . . . . . . . : Node Type . . . . . . . . . . . . : Unknown IP Routing Enabled. . . . . . . . : No WINS Proxy Enabled. . . . . . . . : No Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Intel 21140-Based PCI Fast Ethernet Adapter (Generic) Physical Address. . . . . . . . . : 00-03-FF-FF-36-DB DHCP Enabled. . . . . . . . . . . : No IP Address. . . . . . . . . . . . : 192.168.0.1 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 192.168.0.1 /* Ping ISA防火墙的LAN1接口*/ C:\Documents and Settings\Administrator>ping 192.168.0.254 Pinging 192.168.0.254 with 32 bytes of data: Reply from 192.168.0.254: bytes=32 time<1ms TTL=128 Reply from 192.168.0.254: bytes=32 time<1ms TTL=128 Ping statistics for 192.168.0.254: Packets: Sent = 2, Received = 2, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 0ms, Maximum = 0ms, Average = 0ms Control-C ^C /* Ping ISA防火墙的LAN2接口*/ C:\Documents and Settings\Administrator>ping 192.168.2.1 Pinging 192.168.2.1 with 32 bytes of data: Request timed out. Request timed out. Ping statistics for 192.168.2.1: Packets: Sent = 2, Received = 0, Lost = 2 (100% loss), Control-C ^C /* Ping 位于LAN2的Client1*/ C:\Documents and Settings\Administrator>ping 192.168.2.8 Pinging 192.168.2.8 with 32 bytes of data: Request timed out. Ping statistics for 192.168.2.8: Packets: Sent = 1, Received = 0, Lost = 1 (100% loss), Control-C ^C 位于LAN2的接口都Ping不通,Why?很简单,在Server1上没有到LAN2的路由。我们看看Server1的路由表: C:\Documents and Settings\Administrator>route print IPv4 Route Table ============================================== Interface List 0x1 ........................... MS TCP Loopback interface 0x10003 ...00 03 ff ff 36 db ...... Intel 21140-Based PCI Fast Ethernet Ad <
