Do a
sudo pfctl -sr to show the rules. If you don't see the block rule, you added, you forgot to reload pf with
Code:
# pfctl -vvf /etc/pf.conf
A reload will usually create/configure a pflog0 device.
You can check that with:
Code:
$ ifconfig pflog0
pflog0: flags=141<UP,RUNNING,PROMISC> mtu 33160
priority: 0
groups: pflog
