Limiting Web Access

Good evening,

I'm a volunteer for an organization that is thinking about installing a small computer lab.  One thing that we would like to be able to do is limit the web pages that the computers can view.  I know with a linksys router I can disallow a web page by entering its url.  I would like to be able to flip this around enter the urls that the computers will be allowed to access. 

As I type this, it seems like we could use a proxy server to do this, but I have a feeling a router might be easier to manage/install.

Questions that I have for members that have implemented something like this:

1.  Uptime/reliability

2.  Ease of use for a non-technical person to add a url.

3.  Amount of time to install/configure the solution

Thank you. 

Hello, you can probably do this by using Opendns.  You set up your free account, enter the dns settings in the router and all computers that connect to that portion are filtered.  Simple, efficient, effective, and free. 

Or, how about not doing so and being cool about Internet access? (I dunno, I'm just sayin')

"OMG!  But what about the childrenz!?"

It's okay, the kids will be alright, and the internets will not ruin them.

I second Gary's recommendation of OpenDNS
