Show full answer Show less ## Key Features Introduced Between the Yokohama and Brazil releases, significant new features were introduced in the Australia release family to enhance Reverse Tunnel capabilities: * **Private Connectivity for Zero Copy Connectors:** Enables connections to data sources hosted in private cloud or on-premises environments without exposing credentials or IP addresses. * **Private Relay Deployment:** Allows deployment of a private relay within your private network that establishes outbound encrypted connections to the Reverse Tunnel gateway, with automatic authentication and a MID Server-like placement model. * **Relay Heartbeat Monitoring:** Provides the ability to monitor relay health data directly from the relay record inside your ServiceNow instance. * **Service Endpoint Management:** Supports registration of fully qualified domain names (FQDN) and port numbers for each data source, enabling correct routing of incoming traffic through the gateway to the appropriate relay. ## Activation and Availability Reverse Tunnel is available as the **Zero Copy Reverse Tunnel store app (snzctunnel)** in the ServiceNow Store, starting from the Australia release. Customers can install and activate this app to leverage the new zero copy connector and private relay capabilities. ## Upgrade and Change Notes * No updates, changes, removals, or deprecations were introduced in the Yokohama, Zurich, or Brazil releases for Reverse Tunnel. * All critical new features and activation details are centered on the Australia release. ## Additional Considerations * There are no noted additional requirements, browser requirements, accessibility considerations, or localization updates for Reverse Tunnel across any of these releases. * Firewall inbound ports do not need to be opened due to the outbound encrypted connection model enabled by private relay deployment. ## Practical Benefits for ServiceNow Customers * Securely connect to private cloud or on-premises data sources without exposing sensitive network credentials. * Maintain compliance and security by using encrypted outbound connections and automated authentication. * Monitor relay health easily within your ServiceNow instance to ensure reliable connectivity. * Simplify network management by avoiding inbound firewall configuration changes.
