Block all websites except specified sites.

Hi Guys,

I have a client (mental health department) that has asked me to find out about website blocking.

They have 2 computers that their patients have access too.  basically I want to be able to block all internet traffic/websites, except for a few that they want to specify E>G Training websites etc.

Does anyone nkow of any good software I can put on these 2 computers to do that? I have already looked at Blue Coat K9 Web protection but it only offers category blocking and individual site blocking (I dont really want to manually block every website in the world!)

Any help would be greatly appreciated.

Are you familiar with linux?
This is a kob that would be taken care of easily by a linux proxy using iptables or squid, where all traffic will be dropped and then you have a file that contain the allowed urls only.

I do Squid(Free)! I'd recommend running Squid with Dansguardian ....squid is the best but keep in mind it requires times and skills to install, manage and configure it with other components. I used it in many complex environments with success but again you need  the skill in Linux and squid (open source packages)...
