Security servers and Unified Access Gateway appliances include a Blast Secure Gateway component. When the Blast Secure Gateway is enabled, after authentication, clients that use Blast Extreme or HTML Access can make another secure connection to a security server or Unified Access Gateway appliance. This connection allows clients to access remote desktops and applications from the Internet.
When you enable the Blast Secure Gateway component, Blast Extreme traffic is forwarded by a security server or Unified Access Gateway appliance to remote desktops and applications. If clients that use Blast Extreme also use the USB redirection feature or multimedia redirection (MMR) acceleration, you can enable the View Secure Gateway component in order to forward that data.
When you configure direct client connections, Blast Extreme traffic and other traffic goes directly from a client to a remote desktop or application.
When end users such as home or mobile workers access desktops from the Internet, security servers or Unified Access Gateway appliances provide the required level of security and connectivity so that a VPN connection is not necessary. The Blast Secure Gateway component ensures that the only remote traffic that can enter the corporate data center is traffic on behalf of a strongly authenticated user. End users can access only the resources that they are authorized to access.
