what i want to do is block a range of ip addressess from a text file

this is the format they are in

a sample of around a thousand ranges


 12.24.142.0 - 12.24.152.111

 12.24.152.128 - 12.24.236.207

 12.24.236.224 - 12.25.129.47

 12.25.129.56 - 12.28.138.135

 12.28.138.144 - 12.31.210.119

 12.31.210.128 - 12.33.42.87

basicly its a list of all american IP address ranges. prety much uptodate as i could get.

basicly i want one terminal on my network not to be able to access any american ip ranges

i only have windows home pc but i could run the terminal through one network card with a bridge on my laptop.


any ideas on how i can do this. i know you can get some fire walls to do this but not sure how i could import all of these ranges thanks if you can help
