>From a very nasty experience here @ work, I highly recommend Sonic Wall. I have been trying to bypass it since it was installed but will little luck. Restriction can be based on ip address, and or ip range or even subnet. The sys admin is rather mum about its details e.g. how its deployed on a network etc, but he did say that its damn expensive.

It can also restrict certain websites based on the categories they are in, e.g. software downloads, social networking etc.

If you do implement it, could you send me pointers on how to bypass it? Damn thing has made my life miserable!
