The difference between passive and active FTP data connections, which mode to use, and why active mode fails through firewalls.

Restrict who can connect to your service with per-service ALLOW and DENY lists - single addresses, CIDR ranges and comments.

The roles your GCS service account needs, and the errors you see when they are missing.

The certificates DocEvent presents for explicit and implicit FTPS connections, who issues them, and how to configure your client's trust.

Create an SFS service that gives you FTP, FTPS and SFTP access to your own Google Cloud Storage bucket.
