Hi, I purchased a VPS a few days ago and I'm having huge traffic because a lot of IPs are using the VPS as a proxy.

I managed to setup mod_security2 to deny this connections, now returns 404 or 403. Thats fine, also I can combine it with CSF+LFD to block this IPs. The issue is that there are so many IPs, and the amount of incoming (and outgoing) traffic is a lot.

I was wondering if there is any way to not answer this connections using mod security, i mean instead of return 404, that apache does not respond to the connection (drop the connection)

I will appreciate any idea
