DNS: add external domain to internal server

How do you setup DNS so clients on the internal network can access internal hosted devices.
For example: Domain.Local clients try to go to mail.domain.com and are pointed to mail.domain.local.

Basically just create new zone 'domain.com' on your internal server and populate it with A records for mail pointing to your internal IP's

What DNS server are you on?

You can make an internal only DNS (split DNS) and/or use views in BIND.

What kind of servers are you using?

There is only one service that is not hosted locally, and I can manually add that record. My only real concern was by adding the new forward lookup zone am I going to break something in AD?

No, adding zone is fine, won't cause any harm

But if you only want the internal zone for mail.domain.com and there is also a www.domain.com for example. internal clients won't be able to get to www.domain.com(the external record I mean) without you also adding A record for www...

You won't break anything.

But as smckeown777 you need to add A records for all things that are hosted on domain.com if you want to access them internally.

I am adding an 2010 exchange server, and I need to add autodiscover.domain.com, legacy.domain.com, mail.domain.com
I am also interested to know if I can link the new zone to AD. That way I can manage the new zone in only one server, or do I have to not link the zone to AD and go to each server to add and update the zone.

I did not create the AD integrated zone. I just made the zone stand alone. I should not have to update the zone so after was created it should require maintenance. Besides I cheated. I copied the domain.com.dns file from the first server to the second and just use that copied file when creating the zone.
