Slight typo on http://openbsd.org/faq/pf/tables.html
No grammar rules to consult this time.
table <goodguys> { 192.0.2.0/24 }
table <rfc1918> const { 192.168.0.0/16, 172.116.0.0/12, \
10.0.0.0/8 }
should be
table <goodguys> { 192.0.2.0/24 }
table <rfc1918> const { 192.168.0.0/16, 172.16.0.0/12, \
10.0.0.0/8 }
