  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...   User (192.168.0.1none)): anonymous   331 User name okay, please send complete E-mail address as password.   Password:   230 User logged in, proceed.   ftp> dir   200 PORT Command successful.   150 Opening ASCII mode data connection for /bin/ls.   drw-rw-rw- 1 user group 0 Jul 29 17:58 .   drw-rw-rw- 1 user group 0 Jul 29 17:58 ..   drw-rw-rw- 1 user group 0 Jul 29 17:58 AdminScripts   drw-rw-rw- 1 user group 0 Jul 29 17:58 ftproot   drw-rw-rw- 1 user group 0 Jul 29 17:58 wwwroot   226 Transfer complete.   ftp: 收到 314 字节,用时 0.00Seconds 314000.00Kbytes/sec.   ftp>      此时,我们在Server1上的ftp管理控制台中看看       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 <
