How To :在DMZ网络中部署Internet IP地址

答案是在External1上没有到DMZ网络的路由。

查看一下External1上的路由表:

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 Adapte
(Generic)
===========================================================================
===========================================================================
Active Routes:
Network Destination Netmask Gateway Interface Metric
0.0.0.0 0.0.0.0 61.139.0.1 61.139.0.1 20
61.139.0.0 255.255.255.0 61.139.0.1 61.139.0.1 20
61.139.0.1 255.255.255.255 127.0.0.1 127.0.0.1 20
61.255.255.255 255.255.255.255 61.139.0.1 61.139.0.1 20
127.0.0.0 255.0.0.0 127.0.0.1 127.0.0.1 1
224.0.0.0 240.0.0.0 61.139.0.1 61.139.0.1 20
255.255.255.255 255.255.255.255 61.139.0.1 61.139.0.1 1
Default Gateway: 61.139.0.1
===========================================================================
Persistent Routes:
None

注意看,61.139.0.0网络是通过61.139.0.1这个接口访问的,External1会通过61.139.0.1对61.139.0.0/24网络的数据包进行广播,那么位于DMZ网络中的61.139.0.9、61.139.0.10自然不能获得External发送的数据包。

 

 

 

4、在外部主机上配置到DMZ网络的路由

现在我们在External1上配置到DMZ网络的路由:

C:\Documents and Settings\Administrator>route add 61.139.0.8 mask 255.255.255.252 61.139.0.12

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 Adapter
(Generic)
===========================================================================
===========================================================================
Active Routes:
Network Destination Netmask Gateway Interface Metric
0.0.0.0 0.0.0.0 61.139.0.1 61.139.0.1 20
61.139.0.0 255.255.255.0 61.139.0.1 61.139.0.1 20
61.139.0.1 255.255.255.255 127.0.0.1 127.0.0.1 20
61.139.0.8 255.255.255.252 61.139.0.12 61.139.0.1 1
61.255.255.255 255.255.255.255 61.139.0.1 61.139.0.1 20
127.0.0.0 255.0.0.0 127.0.0.1 127.0.0.1 1
224.0.0.0 240.0.0.0 61.139.0.1 61.139.0.1 20
255.255.255.255 255.255.255.255 61.139.0.1 61.139.0.1 1
Default Gateway: 61.139.0.1
===========================================================================
Persistent Routes:
None
