Subject: best approach for blocklist
Date: Fri, 05 Mar 2010 17:17:36 +0100 [thread overview]
Message-ID: <4B912EA0.1060604@conversis.de> (raw)
Hi,
I'm wondering what the most efficient way to implement a blocklist is. We
are basically talking about blocking a few thousand IPs. Does iptables do
some internal optimizations when blocking based on a source address or
would it be better to, say, create a chain for each class A net (e.g.
83.0.0.0/8) and then add the IPs in that range to that class to make the
matching more efficient?
Regards,
Dennis
