The GNATS system was going through a strange period right around
the time that this PR was submitted, and a lot of PR's got duplicated.

I'm sorry, I erred in not including the current status when I closed
the PR. I believe you will find that both my suggestion (sending a
RST) and your suggestion (sending a host unreachable) are possible
using the new ipfw code in the kernel; the piece of code that you
suggested patching now looks like
icmp_error(*m, ICMP_UNREACH,
rule->fw_reject_code, 0L, 0);
implying that you can set fw_reject_code to ICMP_UNREACH_HOST if you
want. It should probably normally be set to ICMP_UNREACH_FILTER_PROHIB
(which doesn't have the ill effects that ICMP_UNREACH_PORT does on
SunOS).
