　　CentOS 7中設(shè)置ip白名單

　　我想安裝CentOS 7防火墻，所有傳入的請求將被封鎖，除了IP白名單。對于白名單的IP的所有端口都要訪問?

　　adding sources to a zone. First checkout which sources there are for your zone:

　　firewall-cmd --permanent --zone=public --list-sources

　　If there are none, you can start to add them, this is your "whitelist"

　　firewall-cmd --permanent --zone=public --add-source=192.168.100.0/24

　　firewall-cmd --permanent --zone=public --add-source=192.168.222.123/32

　　(That adds a whole/24and a single IP, just so you have a reference for both a subnet and a single IP)

　　Set the range of ports you'd like open:

　　firewall-cmd --permanent --zone=public --add-port=1-22/tcp

　　firewall-cmd --permanent --zone=public --add-port=1-22/udp

　　This just does ports 1 through 22. You can widen this, if you'd like.

　　Now, reload what you've done.

　　firewall-cmd --reload

　　And check your work:

　　firewall-cmd --zone=public --list-all
