IP allowlists

This page describes how to use the IP allowlists connectivity method so that Datastream can transfer data from a source database to a destination.

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.

Set up IP allowlists

If your source database is external to Google Cloud, then add the Datastream public IP addresses as an inbound firewall rule on the source network:

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. The default values are:

   • 1521 for an Oracle database
   • 3306for a MySQL database
   • 5432for a PostgreSQL database
   • 1433 for a SQL Server database
   • 27017 for a MongoDB database

6. Save the firewall rule, and then exit.
