Kubernetes proxy to Google Cloud MemoryStore-Redis

Question

I would like to make Google Cloud MemoryStore-Redis accessible from localhost even without any setup to my local PC (I know it's a security hole but I need a simple setup for everyone from my team ASAP).

My current approach is to use standard .net library and call redis like this:

            ConnectionMultiplexer redis = ConnectionMultiplexer.Connect(
                        new ConfigurationOptions
                        {
                            EndPoints = { ip }
                        });

            var db = redis.GetDatabase();

Because I'm currently hosting everything in GKE, I set up my Gateway/VirtualService/ServiceEntry like this:

apiVersion: networking.istio.io/v1alpha3
kind: Gateway
metadata:
  name: default-gateway
spec:
  selector:
    istio: ingressgateway
  servers:
  - hosts:
    - '*'
    port:
      name: http
      number: 80
      protocol: HTTP
  - hosts:
    - '*'
    port:
      name: redis
      number: 6379
      protocol: TCP      


---


apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
  name: proxy-redis
spec:
  gateways:
  - default-gateway
  hosts:
  - "*"
  tcp:
  - match:
    - port: 6379
    route:
    - destination:
        host: redis-expose-service


---


apiVersion: networking.istio.io/v1alpha3
kind: ServiceEntry
metadata:
  name: redis-expose-service
spec:
  hosts:
  - redis-expose-service
  ports:
  - name: tcp
    number: 6379
    protocol: TCP
  location: MESH_EXTERNAL
  resolution: STATIC
  endpoints:
    - address: X.X.X.X # address provided by gcloud
      ports:
        tcp: 6379      
    
  
---


apiVersion: networking.istio.io/v1alpha3
kind: DestinationRule
metadata:
  name: redis-expose-service 
spec:
  host: redis-expose-service  

Connecting from GatewayPublicIP:6379 works fine from the Kubernetes cluster but not from my local machine (Exception: StackExchange.Redis.RedisConnectionException: It was not possible to connect to the Redis server(s). Error connecting right now.). Any help would be appreciated.
