Subject: Using iptables and ipset to DROP a list of 2 million addresses
Date: Thu, 11 Apr 2024 08:39:40 -0400 [thread overview]
Message-ID: <CAEphJuhKcfOoMvATjubj7T31g32tMqpEKi=yE2OAnNf9768XyA@mail.gmail.com> (raw)
Hi,
I am currently trying to set up a firewall on an Ubuntu 22.04 machine
that will block a list of 2 million plus ip addresses without slowing
the network speed down tremendously. I have tried using ipset but I
get an error that the hash size isn't large enough. I have tried
manually setting the hash size but it only allows that option to be so
large. Is there something I am doing wrong or is there a better way to
achieve this? Any help with this would be much appreciated.
