Cname Record for an External Site

Question

Monday, November 5, 2012 7:17 PM

Hi,

I have an interesting problem.  I have setup a small business with an internal domain of internal.abc.com.  They also have the external site abc.com which is hosted by an external company. 

They have a lotus notes installlation that has an address of notes.abc.com coded into it.  What they were doing befor was going external and then back into their network in order to go to their mail server.  I was trying to make a pointer directly to the IP address of the notes server 172.19.87.x.  I created the A record which works fine, but the fqdn is notes.internal.abc.com. 

I tried to createt a Cname to notes.abc.com, but it comes up as notes.abc.com.internal.abc.com.  Is there a way to create a record that will point to the abc.com domain without creating a primary zone for abc.com?  I am worried that if I create a zone for abc.com, that I will have to maintain all the DNS records internall, as well as externally.  If there is a quick way to have it forward all requests that it does not have an explicite record for to the internet then that would work as well. 

Thanks

You don't need to create a CNAME. Just create a zone with the name of the FQDN and create a blank hostname entry, such as: Create a zone called notes.internal.abc.com, right-click, new Host (A) record, keep the name blank and type 172.19.87.x.

This should help:
