要求:
需要让Linux01通过Linux02访问Linux03,把Linux02转换成一个路由器。
实施步骤:
(1) 准备环境:Linux01(ip:10.0.0.10)Linux02(双网卡eth0:10.0.0.11 eth1:10.0.1.11)Linux03(ip:10.0.1.10)
(2) 配置Linux01,添加路由:route add -net 10.0.1.0/24 gw10.0.0.11
(3) 配置Linux02,开启路由转发功能:echo "1" >/proc/sys/net/ipv4/ip_forward
(4) 配置Linux03,添加路由:route add -net 10.0.0.0/24 gw10.0.1.11
(5) 关闭所有防火墙
