Moved a server recently and in the process lost my iptables rules where I've been collecting every AWS IP range, registration/login probes, log referrer spammers and the rest of useless or dangerous visitors, usually banned by entire IP range of the hosting company. After that, got CSF installed, too, so the syntax of the rules would have changed anyhow.
So, before I start re-building my new CSF rules from scratch, I was wondering if someone can spare theirs. Is there a csf.deny that worked well for you against AWS and such that you can post here? Or parts of csf.deny that deal with traffic from hosting companies and clouds?
