I am blocking a specific IP from the firewall as logged in messages 71.74.56.125. In looking at each block of ip’s and using a CIDR calculator I can’t figure out what range it’s really coming from. The list I have is pretty huge. Is there a tool or a way to ask iptables what rule it matches? Based on all my calculations I don’t have anything declared that would block that IP.

Thanks!

Um, 71.74.56.125 is not part of any of the Class A ranges that you are blocking (62., 77., 78.). So... that sort of implies that something else is blocking it.

Do you care to provide the (sanitized) output of an 'iptables-save' for us to look at?
