TMG 2010 Single NIC & Exchange 2010 Publishing

Hi all,

I'm not sure, if the following scenario being considered is valid:

Internet

  |

Cisco ASA -- LAN
  |
 TMG 2010

We'd like to publish Exchange 2010 in LAN via TMG 2010 in DMZ connected to Cisco ASA.

As I read some Single NIC limitations and this thread , i'm not sure if all Exchange services (SMTP, IMAP, Autodiscover, OWA, ActiveSync, Outlook Anywhere, etc.) are "publishable" via TMG. Is "Server publishing" match SMTP and IMAP?

I'll appreciate any hint as I'm really not sure.

Thanks!
