How to disable Port Scanning on OpenVPN

Web VPS

Hi. I currently run a free VPN service but I have been getting a few abuse reports lately regarding users that are connecting to the VPN and running port scanning tools on big organizations and Universities.

Is there a way I can prevent port scanning through IPTables or other means?

I am not sure how to find out which user is doing it either.

I currently have OpenVPN installed on Centos 5 32 bit.
