先说一点 我这边测试 你这2个公网IP的80端口没有对所有IP开放
[root@niaoyun ~]# nmap -p 80 61.156.170.48
Starting Nmap 6.40 ( http://nmap.org ) at 2016-08-08 23:29 CST
Note: Host seems down. If it is really up, but blocking our ping probes, try -Pn
Nmap done: 1 IP address (0 hosts up) scanned in 3.09 seconds
[root@niaoyun ~]# nmap -p 80 112.73.65.48
