A rule that never matches

Rule 3 below never gets any hits. Why?

1  allow  any -> 10.1.0.0/16  tcp/443
2  deny   any -> 10.1.5.0/24  any
3  allow  any -> 10.1.5.20    tcp/22

A.Rule 3 uses an invalid host IP addressB.Rule 2 matches first, so rule 3 is shadowedC.Rule 1 already allows SSH to the whole rangeD.Firewalls check their rules from the bottom up
