Block to Audio,Video Streaming and upload any attachment

  • All Experts,

    I am using pfSense-2.0.1-RELEASE-i386. I want to block audio, video streaming and stop my LAN users to upload/attach any doc, xls, files. Is there any way to achieve this target. This is very important for me due to security reasons.

    With thanks in advance.
