I have located a number of cidr blocks that I can block in the FORWARD chain to affect my blocking desires thank you for your input.
I will also consider using opendns, but I am not sure that I wish to use a 3rd party service for this. not that i do not believe it would work very well, but I would prefer to keep everything in one place.
I have a post in another topic regarding vpn if anyone would care to help me out with that.
