DNS in virtual machines

[todvard]

Hi,

i have a Xen based virtual machine system. The system has one external IP address and a routed/NAT network for virtual machines. For security reasons i have installed ISPconfig on one of the virtual machines. I wanna keep clear main machine runnig virtual hosts from services except ssh for administering xen.
My problem is, if I am creating a domain in DNS it will contain the internal address of that machine where the ISPconfig is running (eg 192.168.1.1), so the zone isn't good for external querys. Is there any ideas how can I create good zones for both external and internal querys? I'm thinking about using internal/external views capability of bind9. How can i implement that in ISPconfig, which files should i change?

Thanks,
T.
