Firewall questions

[djkball]

I do train and lab P.C's all have full internet access. I am trying to think of a best solution to block the internet access on all the machines ecept 2 domains. ( or websites)

I know a hardware firewall is an option but the place i do training wont pay for that for this room . THis is something i want to just turn on for my own classroom and looking for a cheap /free solution.

Any ideas ?

Can content advisor block all webistes if you put in deney *.* ?

There are free software Firewalls that would help ypu in doing so.

I think the feature is called a white list, where only internet sites on the list will be able to be seen. Might help you google around and see your options

I would put in a false DNS server, and add the 2 sites to the hosts file (/etc/hosts for *nix, C:\windows\system32\drivers\etc\hosts for windows)

Yap this is a good solution.

Log to this page there is a section "Allow only few specific Sites". That explains how to do it.
