Next best firewall after csf?

[roggy]

Hi everyone,
I have set up csf on my VPS hosting, but once set up and configured it starts to send the server load through the roof. I have looked the loads, logged them, monitored them and cannot see what is causing it, yet when I uninstall csf the loads return to normal? Is there a better alternative to csf that others have had experience with that doesn't require perl to start and run? mabybe I will attempt to install csf again on a new VPS and see how it work but not now.
Your recommendations would be much appreciative!

I would recommend you learn more about iptables at it's a good one (as I know)

The next best after CSF would be APF combined with BFD.

Or you could look into dedicated protection. CSF and APF are mainly used as software protection.

Hey,

you should really consider setting up iptables manually with a help from tutorials. That should be enough and it won't increase your server resource consumption drastically.

You may try denyhosts + ddos deflate + as advised (google firewall rules for webserver - if you use it)
