Whitelist IP Address for Vertex Pipelines in a VPC Network with Cloud NAT

[k00kI03]

Hi everyone,

I'm running Vertex Pipelines in a VPC network with Cloud NAT attached. I've configured firewall rules on my target servers to whitelist the IP addresses of my VPC network(NAT). However, I'm encountering issues because the Vertex Pipelines instances seem to be using different public IP addresses each time they run.

I assumed that since the pipelines are running in the VPC and using Cloud NAT, they would use the same public IP address for egress traffic going to other networks. However, I'm seeing a variety of public IP addresses from different subnets within the europe-west2 region (where pipelines are running).

I'm wondering if there's a way to ensure that Vertex Pipelines instances use a consistent public IP address for egress/ingress traffic, or if I need to adjust my firewall rules to allow traffic from a wider range of IP addresses.

Any insights or suggestions would be greatly appreciated.

Thanks
