This setting is disabled by default.

This setting is enabled by default.

Use Blast Secure Gateway for Blast connections to machine Determines whether clients that use a Web browser or the Blast Extreme display protocol to access desktops use Blast Secure Gateway to establish a secure tunnel to Connection Server.

This setting is disabled by default.
