Internal root name server

Hi all,
I am building an internal network behind a firewall (Linux+ipchains),
leaving a registered name server outside it.
To make name resolution working inside, I have set up a box (bind 8.2.2)
as a primary NS and root NS.
In /etc/named.conf I have:
options {
directory "/var/named";
forwarders { xxx.yyy.zzz.qqq; };
};
zone "." in {
type hint;
file "db.root";
};
where xxx.yyy.zzz.qqq is the registered name server.
In db.root I have:
@ IN SOA ns.mydomain.local. hostmaster.mydomain.local. (
1999110201 ; serial
10800 ; refresh
3600 ; retry
604800 ; expire
86400 ) ; TTL
IN NS ns.mydomain.local.
ns.mydomain.local. 604800 IN A 192.168.150.2
mydomain.local. 86400 IN NS ns.mydomain.local.
150.168.192.in-addr.arpa. 86400 IN NS ns.mydomain.local.
In /etc/resolv.conf I have:
domain mydomain.local
nameserver 192.168.150.2
Name resolution works well from inside but I get some error messages in
the logs when I lookup a non-cached address:
named[6800]: sysquery: no addrs found for root NS ()
1) What does it mean and how can I fix it?
2) Is it the right way to setup a DNS behind a firewall?
Thanks,
F.
