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
