I need to block a few websites, and I assume I can do this by different ways:
I have a sonicwall, but no subscription for the content filtering. Other people seem to be successful without subscription, but I am missing something. I cannot add this to a Zone.
Is this possible when you only have a windows internal DNS, and all the request for website access are transferred to a ISP DNS?
3. Proxy Server
No experience here. Do I designate a machine for this? I have a windows 7 machine that only works as quickbooks server.
Maybe setup squid on linux? Can I take a old PC to do this, or do I need a good machine?
