How Blocking Proxy Websites?

[peter]

Hii.. I'm using Wingate 6.6.3 and Pure Sight 3.0 for WingGate. Using WinGate, im blocking all users to access social website like: www.facebook.com, www.friendster.com, www.twitter.com and more others website are not allowed to access. But, the problem is users still can access blocking website using proxy websites, example: unblockwebs.net, www.sneaking.in and so more proxy websites impossible to me to blocking 1 by 1 all the url. My question is, how to blocking all users in my office from using this proxy websites??

Thanks you
Peter

I would recommend using OpenDNS as you DNS provider. This site allows you to manage access to various classes of web sites including proxy and social sites.

Hi labull, thanks for response, i already test OpenDNS and its same like Pure Sight. but blocking websites by inserted the url manually, Difficult to me to search and blocking all proxy websites because so more
url. any software can auto detecting proxy website url and then auto blocking that url?.

If you set up an account (free) in OpenDNS you can choose a broad range of categories of sites to block - such as proxies.

sneaking.in was blocked from my network automatically
