How to block VPN software from clients

Hi,
I have an Astaro ASG 420 at work, I have setup the rules to disallow certain applications (IM,Chat) and some non-work related websites (facebook, twitter, forums) but I discovered that some users are using VPN software (hotspotshield) to bypass the rules. 

How can I detect and/or block such traffic and applications ? 

regards,

  • Hi,

    1. what ASG/UTM version are you running?

    2. are you using the http / https proxy (Web Protection)?
    In transparent mode?

    3. what VPN technology does 'hotspotshield' use? e.g. SSL, IPSEC, L2TP, ...
