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.

Yes that's also fine, go ahead with those settings and you are good to go...
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.
