networking - Egress traffic from GKE Pod through VPN

Question

I have a VPC network with a subnet in the range 10.100.0.0/16, in which the nodes reside. There is a route and firewall rules applied to the range 10.180.102.0/23, which routes and allows traffic going to/coming from a VPN tunnel.

If I deploy a node in the 10.100.0.0/16 range, I can ping my devices in the 10.180.102.0/23 range. However, the pod running inside that node cannot ping the devices in the 10.180.102.0/23 range. I assume it has to do with the fact that the pods live in a different IP range(10.12.0.0/14).

How can I configure my networking so that I can ping/communicate with the devices living in the 10.180.102.0/23 range?
