I think all you'll need is:
pass in quick on $ext_if proto udp from any port 67 to any port 68
When I used DHCP with PF, I found that it just worked without any rules
That's been my experience as well (admittedly on OpenBSD, but it's
basically the same PF). Remember, your NIC's initialization sequence,
which is where the DHCP request will come, happens before PF is
enabled, so you're essentially at a "pass all" sort of a state when the
The one thing to keep in mind is that if you're doing, say, NAT for
some clients behind the box, you can use a rule like this to deal with
any changes in your dynamic IP (which should be extremely rare -- on
Comcast I've had one IP change in 1.5 years, and that was because I was
down for a significant chunk of time):
nat on $ext_if from $int_if:network to any -> (nfe0)
The "(nfe0)" here says "use the IP address of the nfe0 interface,
instead of requiring you to specify the address manually.
