Meu último arquivo pf.conf é o seguinte. Há um par de opções comentadas que eu vou voltar.
Os primeiros, antispoof, se configurados, me impedem de se conectar à interface web do roteador?
Os últimos são os conjuntos int_if, e eu só tenho que defini-los. Um dia.
# This file contains the main ruleset, which gets automatically loaded
# at startup. PF will not be automatically enabled, however. Instead,
# each component which utilizes PF is responsible for enabling and disabling
# PF via -E and -X as documented in pfctl(8). That will ensure that PF
# is disabled only when the last enable reference is released.
#
# Care must be taken to ensure that the main ruleset does not get flushed,
# as the nested anchors rely on the anchor point defined here. In addition,
# to the anchors loaded by this file, some system services would dynamically
# insert anchors into the main ruleset. These anchors will be added only when
# the system service is used and would removed on termination of the service.
#
# See pf.conf(5) for syntax.
