RE: Blocking tens of thousands of IP's

Currently we track all access logs realtime via an in house built log aggregation solution. Various algorithms are setup to detect said IPS whether it be by hit rate, country, known types of attacks etc. These IPS are typically identified within a few mins and we reload to banned list every 60 seconds. We just moved some services from apache where we were doing this without any noticable performance impact. Have this working in nginx but was looking for general suggestion on how to optimize if at all possible.

Depends on the firewall, but our network-guys would refuse to do that (and have so in the past).
Apparently, the performance of firewalls when loaded with thousands of rules isn’t much to brag about ;-)

Additionally, they like to create their rules by hand instead of generating them (old school).

How are the IPs gathered?
