I’m trying to mirror services from an on-prem cluster to a GKE cluster. The on-prem cluster is a k3s installed with k3sup and has three ports open P1, P2, P3. One port is used up by the kube API endpoint, one is used up by a SSH server and one port is open. Let’s call it P3.
The multicluster gateway seems to require two ports: mc-gateway and mc-probe, and as a result the GKE cluster can’t connect to the on-prem gateway. Is there an easy way to resolve this without opening another port?
