I'm running FreeBSD-4.0-STABLE on my set of firewalls, each of which are
equipped with two fxp cards. On each side of those firewalls, I have a
router that runs OSPF. I can see, via tcpdump, that there are hellos
happening on either side of the firewalls, but none of them are getting
through to the other side -- i.e. I don't see the hellos from the internal
router coming out the external interface, and vice versa. This happens
regardless of whether I have firewalling enabled or not, so I'm sure it's
not my ipfw ruleset. 

The first thing that occurs to me is that there's something I'm missing as
far as kernel configuration or sysctls. I compiled with options MROUTING,
but that didn't seem to do the trick. Do i need to run mrouted? Please
advise ... Thanks.
