central database for ip deny

[jehanzaib_kiani]

Hi,

I have 3 servers at different locations and i have different csf.deny on all of them. i want to implement a kind of central database server for all of these servers for blocked ips. also for the csf.allow.
what will be the easiest way to do that?

thanks

guys any one who knows how to apply the central csf.deny or may be from db. i have 20 linux machines and i want to have one central db for all the blocked IPs. i can do this using my own script and read csf.deny from all servers but i think it will be ideal if i can do it in csf itself.
any idea guys?
