Dnscache - problem with resolving from internal network

Hi !

Situation :

Internet gateway with NAT (ext. A.B.C.D, int. 192.168.0.1/24) and dnscache listening on 192.168.0.1
Ftp server running on host 192.168.0.2, staticaly NAT-ed on gateway.

External DNS for zone mycorp.com with record :

ftp 1D IN A A.B.C.D

Question :

How can I make dnscache to resolve ftp.mycorp.com to 192.168.0.2 instead of A.B.C.D ?

TIA.

What you're looking for is referred to as split horizon..
If you're running tinydns (you don't mention).. http://www.purebsd.com/o.daemon.djbdns.php is a decent guide on getting started.[/url]

Thanks for response, term "split horizon" was very helpful.
Here : http://www.guinix.com/technote/dualdns.html I found an article describing what I exactly needed.

I hoped it would be easier - using netware dns proxy it was as simple as putting:

192.168.0.2 ftp.mycorp.com

in /etc/hosts.
