My desktop PC get its IP address from a PPPoA modem connected with ethernet. I
started logging DHCP in PF, to make sure I wasn't dropping anything, but the
*only* packets I'm seeing are incoming broadcast:
pass in on vr0: 10.0.0.2.67 > 255.255.255.255.68: BOOTP/DHCP, Reply,
length: 548
I presume that the DHCP client is bypassing the firewall, but I'm wondering
about these incoming broadcast packets - whether they have already been seen
(and can be dropped) or not. The sessions are renewing without any specific
DHCP rules.
