I would like to bulk import to the IP Filter's Blacklist setting from a file contain IP ranges - e.g. generated from this URL (using the "IP Range" option): [censored]
Is there a way this can be done without having to enter each one-by-one?
The ability to bulk-import IP addresses and ranges will appear in the upcoming version 6.9. The Host settings will be XML-based which will allow you to actually import your own data, e.g. list of IP addresses to block.
