Hi all Common problem - I want to block a country range of IP addresses. I have the ranges in 2 formats, one with the IP followed by subnet mask, 58.14.0.0 0.1.255.255 58.16.0.0 0.7.255.255 58.24.0.0 0.1.255.255 58.29.0.0 0.0.255.255 58.30.0.0 0.1.255.255 58.82.0.0 0.1.255.255 58.87.32.0 0.0.31.255 Code (markup): and the other in CIDR format, Ip address followed by "/15" for example, as a shorthand for the subnet. 58.14.0.0/15 China 58.16.0.0/13 China 58.24.0.0/15 China 58.66.0.0/15 China 58.68.128.0/17 China 58.82.0.0/15 China 58.87.64.0/18 China Code (markup): What I want to know is, is there a way on a Windows 2003 (IIS 6.0) where I can ban these IP ranges in one large batch, rather than entering each one (over 400!) manually in the IPSEC or IIS user interface? Is there for example, a file I can populate with the data? Thanks
