I am facing DDOS attack on VPS. And datacenter can not help in it. It's on port80.
Mod_evasive is installed but its not enough.

I am using this firewall script only on server.

Can anyone suggest me how to protect server from DDOS

what kind of DDOS?
why have you decided that it is DDOS at all?
please provide full information. It is impossible to help when it is unknown what the problem is.

There were hundreds of requests on port 80 and resources were 90% on hardware node. MRTG showed 25000Kbit/second of transfer
Actually Dos attack was on one domain. We removed that domain and all went back to normal.
But I am afraid what if it happens again in future.
