I have several IP's that are clearly up to no good that I want to block.
I found a HowtoForge post on how to use "route" to block an IP.
Code:
route add -host xxx.xxx.xxx.xxx reject
When the server reboots, all of the IPs that I've added to the blacklist are now gone.
How can I keep these IPs from being erased at reboot? Do I need to enter them through ISPConfig somehow?
