You can load data into a table from a file (or for that matter dump
table contents to a file) if you like. If it's important to keep the
table contents across reboots, you probably want to do something like
$ sudo pfctl -t foo -T show >/etc/tables/foo
or perhaps at regular intervals from cron, and declare your table
something like
table <foo> persist file /etc/tables/foo
> as su I type pfctl -t foo -Tl -f /etc/pf.conf but it returns nothing.
If you want to show table contents, a
$ sudo pfctl -t foo -T show
should be sufficient.

Ok,
I think it works now, but I'm sure I missed something, since it
doesn't block the flooder.
