samvb-
I have merged your threads, please do not double-post. If you feel your post has been forgotten, you can reply to your original post after a few days to "bump" it back to the top of the forum.
Now, you've also said two different things between these posts, are you looking to install a program to do this for you, or just a list of sites that you can add to some sort of web proxy?
(To that extent, have you researched, ie GoogleSearched 'free web proxy'? It will probably be a Linux device you can throw on some old hardware)
Thanks,
sicarie
