Yesterday, I have installed Norton Personal Firewall 2005. Once it was installed, I tried to access the internet, but this resulted in a message like 'Server not found' or 'Page could not be loaded'. I do not remember exactly, but internet access was not allowed. (Apparently, the firewall was working...). I tried to get to the settings for the firewall (via the menu Options), but I got a message like 'You do not have enough privileges to [...]' (again I don't remember the phrasing). I messed around for a little while, and then I decided to uninstall the firewall, for the time being. I would like to give it another try, but before doing so, I would like to know what has gone wrong in my first attempt. I suppose that the default settings of the firewall should allow internet access to the home page of my ISP. And what is this talk about privileges?
I also messed around with the (toggle) button 'Allow traffic' and 'Block traffic'. Changing the setting did not have any effect.
Thanks in advance for any reaction.
