Query Source not applicable for root queries?

Hi.  We're running BIND 9.2.4 under a Veritas cluster on Solaris 8.  I've d=
one some searching on the list archives for this, but either I missed it, o=
r it isn't there.

This past weekend, we swapped to new firewalls and saw a bunch of denies.  =
Apparently the old FW rules were built slightly differently, and this issue=
 never came up because of it.  It appears that all the denies were queries =
to the root servers coming from the physical NIC, instead of the virtual as=
 I intended.  This surprised me, since I set the query source in my options:

options {
        directory "/usr/dns/bind/data";
        pid-file "/usr/dns/bind/etc/named.pid";
        listen-on port 53 { 162.131.38.89; };
        notify yes;
        query-source address 162.131.38.89 port *;
        transfer-source 162.131.38.89;
        notify-source 162.131.38.89;
        allow-query { any; };
        allow-transfer { localhost; };
        transfer-format many-answers;
// Ran out on 11/17/03 in the afternoon (4-5pm) and at night (9pm)
// So increasing from 5000 to 8000
        recursive-clients 8000;
        tcp-clients 100;
        provide-ixfr yes;
        zone-statistics no;
};

Did I screw up the config, or is there possibly a bug somewhere?

Thanks for any help!
