## Australia

The ServiceNow® Reverse Tunnel application enables zero copy connectors to reach private cloud or on-premises data sources through encrypted outbound connections without having to open inbound firewall ports. Reverse Tunnel is available in the Australia release.

### What's new

-   **[Private connectivity for zero copy connectors](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/integrate-applications/exploring-reverse-tunnel.md)**

    Connect zero copy connectors to data sources hosted in private cloud or on-premises networks without exposing data source credentials or IP addresses. The Reverse Tunnel gateway routes encrypted traffic between Workflow Data Fabric and private relays deployed in your private network without decrypting that traffic.

-   **[Private relay deployment](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/integrate-applications/connect-customer-relay.md)**

    Deploy a private relay in your private network to establish an outbound encrypted connection to the Reverse Tunnel gateway. The relay uses the same placement and connectivity model as a MID Server. Authentication is handled automatically.

-   **[Relay heartbeat monitoring](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/integrate-applications/monitor-relay-health.md)**

    Monitor relay heartbeat data directly from the relay record on your ServiceNow instance.

-   **[Service endpoint management](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/integrate-applications/manage-relay-services.md)**

    Register the fully qualified domain name \(FQDN\) and port number of each data source to the relay. The gateway uses registered service endpoints to route incoming traffic to the correct relay.


### Plugin information

-   **New plugins**

    The following plugin was added in the Australia release:

    Zero Copy Reverse Tunnel \(`sn_zc_tunnel`\): Provides the interface to manage private relays, service endpoints, and relay properties for private connectivity through the Reverse Tunnel gateway.
