Inter-subnet communication within the same VPC for PSC services

[MH1169]

Hi,

I have a single VPC with subnets in 2 regions.

• SG - 1 subnet where connected PSC endpoints are attached to. Another subnet for VMs.
• HK - 1 subnet for VMs

Inter-subnet communication between SG and HK VMs are working well by creating a firewall rule to allow ingress traffic from subnet IP range.

However, the HK VM is unable to reach (ping, curl) the connected PSC endpoints in the SG subnet.

Is there any additional firewall rule I need to add to make the connectivity successful or do I need to create additional entries to have the same PSC endpoints connected to the HK subnet?

Thanks

At the moment, Google Cloud does not support Cross-region Private Service connect which would have allowed you to reach Private Service Connect endpoints from a different region as the PSC's.
