Can Symantec Mobile Security devices (PDA's, smartphones) be updated from an internal server rather than from public LiveUpdate servers?
It is possible to update from an internal server. The suggested way to do this would be to:
1. Setup a LiveUpdate Administrator 2.x (LUA 2.x) or LiveUpdate Administration Utility 1.x (LUAU 1.x) server inside the internal network which has Internet access
2. Configure it to download definitions for Mobile Security
3. Configure the distribution center on the DMZ network server. (This should be accessible by HTTP using port 80)
4. In the LiveUpdate configuration file for each mobile device, configure the URL of the DMZ server repository location
Details for all the supported methods of updating content (LiveUpdate Repackager, etc) can be found in the Implementation Guide on the product CD, and in the articles referenced below.
