I do not see the use of "private interior gateway protocol" on a public
interface, so why allow the packets.
And if the Cisco has no  one to talk to, why litter the LAN?
When you "tried" the allow rule, I was thinking of why not try to disallow
it? The ipfw rules are there to enable what you need and not to let
through what you don't know. Isn't it?
