I've got a Windows Server 2003 hosted server experiencing what appears to be brute force SQL attacks. The firewall provided by the hosting service sucks and I need another option. I don't have the ability to use an appliance and need to do some sort of virtual firewall or software firewall.
Many of the IP addresses attacking me originate in China. I would love to be able to block by country.
I am extremely familiar with SonicWall products, but they don't appear to make anything like this.
