@cmb991:
DNS filtering using that would be awesome, we already have it installed. but there isn't anyway to do categories…
Some others have asked to get that incorporated into the package which I should be able to do at some point…. In the meantime, just download the Feed that you use into /var/db/pfblockerng and extract the archive. The extraction should create the subfolders for the Feed in that base folder.
Then add a new DNSBL Alias, and in the 'Source Fields', map to the category folders that you would like to use… Add a new Source line for each category.
You could also rig a cron task to download once/day and extract to the same folder.
