Google Cloud VPN - Egress from GCP to on-premise pricing clarification

Question

Considering the Google Cloud VPN for networking Google Cloud platform to On-premise as per the following https://cloud.google.com/vpn/docs/concepts/overview

Given that the Cloud VPN tunnel connects to a gateway in GCP, below is the pricing for egress - https://cloud.google.com/compute/pricing#general

I would like to know what would be the exact cost for egressing from GCP to the on-premise server on that case based on different line items present in the pricing above. Would the regular 'internet egress rates' apply for my usecase?

Answer 1

IPSec traffic are charged as if the traffic were regular egress traffic. There could be two scenarios:

1. If the Cloud VPN tunnel connects to a gateway in GCP, egress pricing to the region containing that gateway applies as per general network pricing .

2. If the Cloud VPN tunnel connects to a gateway outside of GCP, Internet egress rates apply.
