   Linux简易路由器
   
   范例：设定如下网路系统之主机当做路由器
   
   1.设定网路介面，其中eth0为192.168.0.1，eth1为192.168.1.1
   
   vi /etc/sysconfig/network-scripts/ifcfg-eth0
   
   
   DEVICE=eth0
   ONBOOT=yes
   BOOTPROTO=static
   IPADDR=192.168.0.1
   NETMASK=255.255.255.0
   NETWORK=192.168.0.0
   BROADCAST=192.168.0.255
   
   
   vi /etc/sysconfig/network-scripts/ifcfg-eth1
   
   DEVICE=eth1
   ONBOOT=yes
   BOOTPROTO=static
   IPADDR=192.168.1.1
   NETMASK=255.255.255.0
   NETWORK=192.168.1.0
   
   
   service network restart
   
   
   
   2.启动IP FORWARD
   
   echo 1 > /proc/sys/net/ipv4/ip_forward (可以直接将这一行加入/etc/rc.d/rc.local档案中)
   
   
   
   3.观察路由情况
   
   
   
   route
   
   Kernel IP routing table
   Destination Gateway Genmask Flags Metric Ref Use Iface
   192.168.1.0 * 255.255.255.0 U 0 0 0 eth1
   192.168.0.0 * 255.255.255.0 U 0 0 0 eth0
   
   
   
   
   4.设定192.168.0.0网域的client电脑
   
   
   
   IP:192.168.0.10
   Gateway:192.168.0.1
   netmask:255.255.255.0
   network:192.168.0.0
   broadcast:192.168.0.255
   
   5.设定192.168.1.0网域的Client电脑
   
   
   
   IP:192.168.1.10
   Gateway:192.168.1.1
   netmask:255.255.255.0
   network:192.168.1.0
   broadcast:192.168.1.255
   
   
   
   6.设定192.168.2.0网域的Client电脑
   
   
   
   IP:192.168.2.10
   Gateway:192.168.2.1
   netmask:255.255.255.0
   network:192.168.2.0
   broadcast:192.168.2.255
