I've a VPS Server running CENTOS 6.7 x86_64 with CSF Firewall activated. Sometimes I see in "Firewall Deny IPs" that blocks suddenly connections from my country (Spain) to some of my clients.
Not with everybody and not everyday, but 2-3 times per week I've to unblock manually some of my clients' IPs because CSF is blocking them.
How can I configure it for not blocking connections from Spain and working the same way until now with the rest of the world? I don't want to connect ONLY from Spain, I want not to block any IP from Spain.
