Configure connectivity

Overview

In this section, you learn how to use Datastream's public IP addresses to configure network connectivity between a source database and a destination.

Configure connectivity using IP allowlists

For Datastream to transfer data from a source database to a destination, the destination first needs to connect to this database.

One way to configure this connectivity is through IP allowlists. Public IP connectivity is most appropriate when the source database is external to Google Cloud and has an externally accessible IPv4 address and TCP port.

If your source database is external to Google Cloud, then add Datastream's public IP addresses as an inbound firewall rule on the source network. In generic terms (your specific network settings may differ), do the following:

  1. Open your source database machine's network firewall rules.

  2. Create an inbound rule.

  3. Set the IP address of the source database to Datastream's IP addresses.

  4. Set the protocol to TCP.

  5. Set the port associated with the TCP protocol to 1521.

  6. Save the firewall rule, and then exit.
