To see the rules will be helpful. In my firewall the first two rules are
the following.
# Allow loopbacks, deny imposters
${fwcmd} add 100 pass all from any to any via lo0
${fwcmd} add 200 deny all from any to 127.0.0.0/8

If I understood correctly, once a rule is matched the rest are skipped.
I hope it helps.

Regards,
Ramon
