Question : Exchange server 2007 / windows server 2003- domain authentication question

Hi,
I have a domain that is called "mycompany.local" in Active Directory.
When installing Exchange server 2007 I ran into a problem trying to get Outlook Anywhere to work. I can't get it to work if the Exchange server is not accessed with the ".local" domain name, autentication don't work if I define an external hostname with ".com" domain.
I can edit all the hosts files and enter the ".local" domain name there but we use NAT and the hostname is different when the users is inside or outside the firewall.

How can I make this work?
Does the AD domain need to be the same as external domain to make Outlook Anywhere work or is there a way around this?
Is it a way to make Outlook Anywhere work without renaming/reinstalling the domain?
