DNS - IP Resolution within a DMZ

[Chris Balcer]

Alright, here's the situation. We have a website which is hosted
outside the DMZ, we get the Web Logs from that server, however because
the DNS Server is located within the DMZ no public name resolution is
available.
We have seen several web services that will resolve the addresses, but
we need to resolve a list of IP addresses rather than one at a time.

Anyone have any ideas how to get this information? Or, if you don't
see what I am asking, please post and let me know any questions you
might have.

Chris,

Is the Web server on the internet example:
internet-------->websever---------->router------->firewall-----Internal Lan.

|----->DMZ

Can you use a host file?

 

[William Stacey]

So you need servers in the DMZ to be able to resolve public addresses? If
so then you can use hosts file, setup a dns server in the DMZ that only dmz
hosts can send queries to and that server forwards to ISP, or point the
server's DNS addresses to the ISP so they can use that directly.

 

[Michael Johnston [MSFT]]

You have a few options. Setup a hosts file with the needed entries. Configure the DNS server with the zone that will resolve the external website. Or configure
the DMZ DNS such that it can resolve Internet names. Is there a reason it's not setup for Internet name resolution? What's the point of having a DNS server in
the DMZ if it cannot resolve Internet names?

Thank you,
Mike Johnston
