You can install the BlackBerry® Pushcast™ Software behind your organization's firewall to maintain and manage security, user accounts, and manage content locally. If a BlackBerry Pushcast Software user in your organization wants to send content to a BlackBerry® device, the user must select the Mobile Only or Both (Desktop and Mobile) delivery method. The BlackBerry Pushcast Software sends an encrypted email message with the content delivery instructions to the BlackBerry device before it sends the content.
The BlackBerry Pushcast Player must have access to the BlackBerry Pushcast Software server using an HTTPS connection over port 443. To provide the BlackBerry Pushcast Player on a device with BlackBerry Internet Service network connection, with access to the BlackBerry Pushcast Software, you must permit inbound HTTPS traffic through the organization's firewall to the BlackBerry Pushcast Software server. When you configure the network connection on the BlackBerry Pushcast Player to be MDS, the BlackBerry Pushcast Software only requires the BlackBerry MDS Connection Service.
Alternatively, you can place the BlackBerry Pushcast Software server in a DMZ that permits inbound HTTPS traffic from devices that use the BlackBerry MDS Connection Service and devices that use the BlackBerry Internet Service.
