Block all sites except a handfull

Hi,

It is possible to block all web sites except a hand full that I want to allow?

Thanks!

First off, welcome to the forums and Comodo community.

I can think of a way to get what you’re after.

If you create a network rule at the top of the rule stack:
BLOCK TCP OUT from IP [Any] to IP [Any] where Source port is [Any] and Destination port is in [80,443]
… you will have killed all web page access using standard HTTP (port 80) and SSL (port 443)

If you added another rule (at the top, above the previous) to:
ALLOW TCP OUT from IP [Any] to IP NAME: [google.com] where Source port is [Any] and Destination port is in [80,443]
… you should have added access to google.com using standard HTTP (port 80) and SSL (port 443)

… repeat this last rule for the other 3 web-sites, and you should be good.

5 rules in all… 4 to implicitly allow the ones you want, and one catchall beneath them to block all others.

And make sure they are grouped at the top of your rules with the block one listed last.
