Thanks for your reply.

Actually, that is what I had already done:
ipfw add 10 check-state
ipfw add 11 allow tcp from any to me 25 setup limit dst-addr 32
ipfw add 12 check-state
ipfw add 13 allow tcp from any to me 25 setup limit src-addr 4
But it seems I never get to rule 12/13. All "ipfw show" shows, is activity
on rule 10/11. That is why I figured I made an error somewhere. Does not
rule 11, indeed, function as an 'early-out'? (undesired).
Thanks,
