No, it's a good question. I'd want to try it first; it would depend on whether it's dropped by an ingress filter or an egress filter. I'm not that familiar with ipfw, but I guess I should be.

If not, this would be a good "junior kernel hacker" task as well. -- "Where am I, and what am I doing in this handbasket?"
