The registration status in the Relay \[sn\_zc\_tunnel\_relay\] table must be Successful. Role required: sn\_zc\_tunnel.relay\_manager ## About this task Service endpoints specify the hostname and port of each data source routed through the relay. ## Procedure 1. Navigate to **All** > **Private Relay** > **Relays**. 2. Open the relay record. 3. In the relay record, select **Unlock Services** to unlock the Services field. 4. Select **Lookup using list** to open the Service Endpoints list. 5. Select **New**. 6. Enter a name for the service endpoint and the FQDN and port number of the data source. For example: `acme.snowflakecomputing.com:443`. When creating a Zero Copy Connectors connection, the connection URL hostname must exactly match the fully qualified domain name \(FQDN\) registered as a service endpoint. 7. Select **Submit**. 8. Save the relay record. ## Result The new service endpoint is reported to the gateway, which routes incoming traffic from Zero Copy Connectors to the correct relay. ## What to do next If the backend data source has an IP allowlist restriction, verify that the relay is running on a machine whose IP address is on the allowlist.
