Does anyone know of a way to easily block foreign subnets? i.e. I only
want our firewall to answer to US based subnets. Our logs show that
most attacks are coming from foreign sources. Ideally, I'd like to
have them broken down by country, and I've found databases online for
sale. Are there any reliable free subnet/country databases available?
And, what are your thoughts on something like this?

On that note, does anyone know of a firewall with this feature built
in? Or would the blocking firewall still be susceptible to attacks?
