Static IPs

Configure network restrictions to allow Velvet's static IP addresses

If your database(s) are behind a VPC or firewall, you'll need to configure the network restrictions in your cloud provider to allow Velvet to connect to your database.

Velvet's Static IPs

You'll need to configure all 5 of these IP addresses for TCP traffic

Cloud Provider Guides

Depending on your setup, you might need to allow all TCP traffic or just specific ports for your database type (PostgreSQL, MySQL/MariaDB, or MongoDB).

Note: be sure that your database has access to the public internet, with either it's own public IP address or access via a proxy server (e.g. a bastion host).
