I have a newbie-ish question.  I was wondering which interface I should be
naming in my ipfilter rules if I wished to firewall a DSL connection that
uses PPPoE.  I'm using rp-pppoe with the DSL modem connected via an Ethernet
cable to le0.  When the DSL connection is established, ppp0 is configured.
So the question is: should I be filtering on the ppp0 interface?

	Thanks,
