What is the best way to block Russia and Ukraine ip addresses?
I am using asp.net C# and IIS7 on a Windows Web Server 2008 R2.
I am using a Windows Firewall inbound rule to block ip addresses, but it is impossible to keep up with the ever changing Russian and Ukraine ip addresses. Is there a SIMPLE way to block multiple address ranges. For instance, is there a way to IMPORT a list of blacklisted ipaddress into my rule? Or, some other simple method of blocking?
Any suggestions welcome.
