Subject: dns transfer through ipfw keep-state rule not working

In a somewhat desperate attempt to convince my firewall to allow our
upstream provider to perform a zone transfer, I've added the following
line to the ipfw firewall.

        $fwcmd add allow all from 209.16.228.146 to $ns1 keep-state in via
$oif

However, this is still not allowing a zone transfer.  On occasion, the
secondary will write a file with a somewhat garbled name for the zone to
be transfered, but it is blank.

This firewall entry however, works. 

        $fwcmd add allow all from 209.16.228.146 to $ns1 in via $oif
        $fwcmd add allow all from $ns1 to 209.16.228.146 out via $oif

Why doesn't the above dynamic rule work?

My rc.conf options section is as follows.

TIA,
