I agree. I solved this all with djbdns but it is convoluted. I created two
aliased IPs on my internal interface (you really only need one but I found
two simpler for other reasons).
tinydns runs on ...161 and serves my internal IPs only.
dnscache runs on ...160 and forwards internet IPs and my internal IPs.
All interior boxes are configured to use ...160 as the dns server.
# configure tinydns to serve my internal IPs
tinydns-conf tinydns dnslog /etc/tinydns ....161 # dns
./add-ns parrotchat.net ....161 # dns
./add-ns 168.....in-addr.arpa ....161 # dns
./add-host ...
# configure dnscache to forward external IPs and cache my internal IPs
dnscache-conf dnscache dnslog /etc/dnscache ....160 # dnsx
...
cd /service/dnscache/root/servers/
echo ....161 > parrotchat.net # 161=dns
echo ....161 > 168.....in-addr.arpa # 161=dns
# Note: modify clients to use ....160 # dnsx
