CentOS 7中如何设置ip白名单

CentOS 7中设置ip白名单

我想安装CentOS 7防火墙，所有传入的请求将被封锁，除了IP白名单。对于白名单的IP的所有端口都要访问?

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
