you can use serverless VPC access:

use case: Your serverless environment needs to access data from your on-premises database through Cloud VPN.

Check this discussion. You can only setup Cloud VPN over VPC networks. GCE instances and GAE flex environment are designed to use these networks.

If you are using GAE standard environment you would have to forward the GAE traffic to a GCE VM but this is only possible via an external IP. The GCE VM would be acting as a proxy.

In any case you need a physical device on your premises.
