You are missing the point. The firewall test sites that don't shoot
through NAT do not tag the secondary off internet address on to
their attack packets. In those tests, everything comes back perfect
because they are being rejected by the router.

Now if the test site took your secondary off Internet address from
your initial SYN packet to log into their site and probed you, the
router would pass their probes right through.
