Blocking foreign country IP addresses with active response (shun).

I have everything I need to start blocking foreign country IP addresses except one thing and that's the enormous list of IP addresses.  There are some great websites out there to find the addresses I need but it's going to take me months to input everything.  Does anyone have any hints on how to do this?  Maybe some kind of CSV import?

Thanks,

Mark.

  • Never mind.  I asked SecureWorks to do Geo-Blocking and that did the trick.  For anything else that gets through I'm automatically shunning connections to our unused IP addresses and to/from ports on public IP's that are in use.  So far it's working great.  I am also able to automatically shun Email rejects from our Sophos Email appliance.
