Deploying AppWorks & ECM Everywhere to view content from IPAD

Hi

We have a requirement to enable mobility for users to be able to login to content server using ECM Everywhere App on IPAD to view/search for documents from enterprise workspace.
Questions:

  1. Since the users are on the field, is it required to install OTAG on a server floored in the DMZ. FYI: Mobility will be enabled only for authorized personnal who have a valid account in Windows AD.

  2. Is OTAG v1.1.6 compatible with Windows 2012 R2, SQL Server 2012 SP1 and OTDS v10.5

Appreciate your responses.

Vijhay Devarajan.
