把HTTP服务通过200.200.200.2发布到公网
Warning:The port 80 is well-known port. If you continue it may cause function fa
ilure.
Are you sure to continue?[Y/N]:y 输入y
13.Client访问HTTP
在client 1的客户端信息选择HTTP Client，输入http://200.200.200.2/index.html，点击获取
测试
1.PC1 ping PC4 可以ping通
2.PC1 ping client 1 可以ping通
3.断开S1和S3的连接，PC1 是否能ping client 1 可以
断开S3和R1的的连接，PC1 是否能ping client 1
