The way our firewall controls are, I have no way of unblocking by range, so there's no way to do this easily. I can't just mass-remove entire ranges, I have to go one by one on the list and delete each IP that falls in one of those ranges. I've removed a large group of them that came from the 162.158 range and the 172.64 range though, mostly blocked for cPanel or mail server logins. Does it work now?
