need advise

Hi,

We have our internal dns configured with the name company.local. Our company
has a main office and several branch office. The vpns between the office are
configured via a ISP.
People use the public dns name "webmail.companyname.com" to synchronise with
their mobile telephone (exchange).

Now the company decided to have these mobiles also configured as a "branch
office" in the VPN. As DNS Servers these mobiles will have our internal DNS
servers configured.
How can i make sure our internal DNS servers can resolve
webmail.companyname.com to a internal address?

Thx.

Ramon

Easily. Create a companyname.com zone on your internal DNS, make it AD integrated, then create any and all external records, such as webmail and provide the internal IP, and assuming you have your web service hosted externally, you will also have to create www, a blank FQDN, FTP, and whatever other records are on the outside world, and provide the external IPs.

Nice blog article Ace.

(Sub your own domain in place of "domain.tld".)

Would it also be possible for Ramon to use a deviation of Scenario 2 in
your article in that a new zone named "www.domain.tld" and use a "blank
host record" resolving to the internal IP?

This would provide the same effect with out the need or worry about
"...any and all external records, such as webmail..." likely exist in
the parent domain "domain.tld".

Thanks, Grant.

Yes, he can do that as well. Essentially if he does create a www.domain.tld, he is creating a separate namespace. This means that any queries for domain.tld will not be checked against that zone, since they are different. Then just create a blank hostname entry giving it the internal IP.

Even though it will alleviate having to create all the external resources, the only thing is all connections to that address must be done with the www. If attempting to go to http://domain.tld, it will resolve the external IP. The only way around that is create the domain.tld zone, and create everything outside in it, too.

By employing "split horizon" DNS service and populating your internal DNS database with the appropriate data.
