Not able to port forward from local to redis server in wrokload in GCP

I am trying to connect to redis cache in dev server which is a pod in GCP. we are trying to connect it through a proxy server using below command

gcloud beta compute ssh --zone "<zone>" "proxy-server" --project "project-name" --internal-ip --ssh-flag="-NL <local_port>:<redis-server-ip>:<port>"

but its throwing error in google cloud console installed in my windows system
error is ‘unknown option "-NL"’

ERROR: (gcloud.compute.beta.ssh) [C:Users<user-dir>AppDataLocalGoogleCloud SDKgoogle-cloud-sdkbinsdkputty.exe] exited with return code [1].

but its running fine in mac, please help me in resolving the issue at the earliest.

As suggested by one of the answer, tried running below command

kubectl port-forward pod/pod-58759-s4wfz 6377:6379

getting this error now:

C:Windowssystem32>kubectl port-forward pod/pod-587597c46d-s4wfz 6377:6379

    After 1 day of effort I found an answer which corrected my command, just need to use below command, in place of -NL we should use -N -L in windows

    gcloud beta compute ssh --zone "<zone>" "proxy-server" --project "project-name" --internal-ip -- -N -L <local_port>:<redis-server-ip>:<port>

    Putty SSH (and the OpenSSH client for windows as well) does not support the -N flag. But

    gcloud beta compute ssh --zone "<zone>" "proxy-server" --project "project-name" --internal-ip --ssh-flag="-L <local_port>:<redis-server-ip>:<port>"

    should work just fine on Windows.

    If your redis server is deployed on GKE, you can use kubectl port-forward. It should look like

    kubectl port-forward pod/POD_NAME local-port:redis-server-port

    And use localhost:local-port to connect to your redis server

    This should work regardless of the OS
