How can I block IP range or entire country on CentOS 7 with FirewallD? The IP range starts with 180.76.15.* and is Chinese IP.
The command below works for single IP but not for range:
firewall-cmd --permanent --add-rich-rule="rule family='ipv4' source address='18.104.22.168' reject"
I tried with this command for the range but without success:
firewall-cmd --permanent --add-rich-rule=“rule family=‘ipv4’ source address=‘180.76.15/24’ reject”
