#
# Default PF configuration file.
#
# 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.

Same (again working as expected with a wired connection, and Apple DNS in wifi). The only issue is the visible IP in Wifi.
