By the way, among my tests I've discovered that connectivity issues re-
occur as soon as I mix network ranges and IP addresses within the same
table (not even pf restart seems to make it work properly again). I
used to have a script to populate a separate table with the spammers
and from time to time I was adding network ranges when multiple (many)
IP addresses within the same range were bombing me so I know it worked
pretty well .... even when IP addresses were overlapping already
specified ranges.

Ex.
120.30.0.0/24
213.156.32.2
.........
