We have a Kubernetes cluster running on GKE, using its own VPC created for this with a subnet of 10.184.0.0/20
. This cluster has a workload that has been assigned an external load balancer towards public access, along with an internal cluster IP towards internal communication. The subnet of the services is 10.0.0.0/20
.
There is a google cloud Classic VPN setup on the same VPC to be able to access the private network.
We have another system hosted on-premise that is connecting via the above VPN using a tunnel. The on-premise network can ping the Nodes in the VPC via their private IPs on the subnet 10.184.0.0/20
, but is enable to ping / telnet to the cluster IP which is on the subnet 10.0.0.0/20
.
Is this possible to achieve?
