How To :配置ISA防火墙作为网络间的路由器

/* 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),

^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),

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 Adapter

Active Routes:

0.0.0.0 0.0.0.0 192.168.0.1 192.168.0.1 20
127.0.0.0 255.0.0.0 127.0.0.1 127.0.0.1 1
192.168.0.0 255.255.255.0 192.168.0.1 192.168.0.1 20
192.168.0.1 255.255.255.255 127.0.0.1 127.0.0.1 20
192.168.0.255 255.255.255.255 192.168.0.1 192.168.0.1 20

255.255.255.255 255.255.255.255 192.168.0.1 192.168.0.1 1
Default Gateway: 192.168.0.1
===========================================================================
Persistent Routes:

默认路由是192.168.0.1,没有到LAN2的路由。对于此情况,你需要添加到LAN2的路由,或者重新设置默认网关为ISA防火墙的LAN1接口。在具体采用哪种方式时,你需要根据网络的环境来决定。对于不能修改默认网关的情况,例如此主机是另外的网络出口的情况(如此计算机上还接有另外一个网卡,连接到Internet),你需要添加到LAN2的路由。

 

 

6、在LAN1的Server1上添加LAN2的路由

在Server1的cmd下运行route add 192.168.2.0 mask 255.255.255.0 192.168.0.254,然后看看路由表:

C:\Documents and Settings\Administrator>route add 192.168.2.0 mask 255.255.255.0 192.168.0.254 -p

C:\Documents and Settings\Administrator>route print
