Forward DNS lookup to different DNS Servers


I have an intranet and an internet DNS domain hosted by different servers. What I want to know is can I have a computer inside my LAN get an address, say printer.domain.com, from the internal DNS server yet have a www.domain.com query be forwarded to an external DNS server?

I used to host my own website internally, so the www.domain.com was answered by my internal DNS server. I've since changed to an external host for my website, so I took the www hostname out of my internal facing DNS server and added it to the external facing DNS server at my web provider. My problem is now www.domain.com is answered correctly from the outside, but when I type www.domain.com inside my lan, I get a "Server Not Found" error. My internal DNS is setup to forward queries, but apparently it won't forward queries for the domain.com network.

I can try to explain it better if this is confusing. I need to know if this is a BIND DNS thing or is my setup messed up somehow.

Well, nevermind. I added the IP address to the internal DNS and it worked just fine.

Hello there;

I used to have similar setups to that you describe. Usually, one of my customers had a registered DNS domain which was used also in the intranet. Since the internet services boiled down to web, mail and eventually ftp, all I used to do was add CNAME records for those servers. If the website was hosted at 'hosting.isp.tld' and the intranet/internet domain was 'mydomain.pt' I'dd add a 'www in cname hosting.isp.tld' to my zone...
These days I prefer to have different namespace for the intranet hosts. Usually I grab the domain name and suffix it with '-lan', like 'mydomain.pt' -> 'mydomain-lan.pt'... It's just more practical and less confusing.

Cheers
