Title: ConfigServer Security & Firewall - blocking a range of !P addresses Post by: admin on December 19, 2017, 06:26: PM If you need to whitelist or block a range of IP addresses using CSF, it can be done, but you need to use the CIDR format.
For example, to block 192.168.0.0 to 192.168.0.255 you would add 192.168.0.0/24 to the blocked list. This tool is helpful too: http://ip2cidr.com |
