Allowlisting IP Addresses for Estuary Flow

When configuring systems that interact with Estuary Flow, it's crucial to ensure that the necessary IP addresses are allowlisted. This allows communication between Estuary Flow and your data systems. The IP addresses you need to allowlist depend on the data plane you use.

Data Plane IP Addresses​

You can find the IP addresses relevant to your use case in the Admin section of your dashboard. To do so:

  1. On the Settings page, find the Data Planes section.

  2. Choose between the Private and Public tabs based on your use case.

    Make sure to select the desired data plane when configuring a connector as well.

    If you wish to use a public data plane, Estuary currently offers AWS eu-west-1 and GCP us-central1 options.

  3. Find the CIDR Blocks column in the Data Planes table. This column includes a comma-separated list of IP addresses for that data plane.

    Ensure that these IP addresses are allowlisted on both the source and destination systems that interact with Estuary Flow.
