That's how the PF firewall looks at everything -- from the perspective of the OpenBSD box, which in this case is a firewall.

Firewalls - FreeBSD FreeBSD has three firewalls built into the base system: PF, IPFW, and IPFILTER, also known as IPF.FreeBSD also provides two traffic shapers for controlling bandwidth usage: altq (4) and dummynet (4). ALTQ has traditionally been closely tied with PF and dummynet with IPFW.Each firewall uses rules to control the access of packets to and from a FreeBSD system, although they go about it in
