You have set up a Compute Engine VM instance as a NAT gateway and created a route with the following command:
gcloud compute routes create no-ip-internet-route \
--network custom-network1 \
--destination-range 0.0.0.0/0 \
--next-hop-instance nat-gateway \
--next-hop-instance-zone us-central1-a \
--tags no-ip \
--priority 800
gcloud compute routes create no-ip-internet-route \
--network custom-network1 \
--destination-range 0.0.0.0/0 \
--next-hop-instance nat-gateway \
--next-hop-instance-zone us-central1-a \
--tags no-ip \
--priority 800
To ensure existing instances use this NAT gateway, what command should you run next?
A
sudo sysctl -w net.ipv4.ip_forward=1_
B
gcloud compute instances add-tags [existing-instance] --tags no-ip
C
gcloud builds submit --config=cloudbuild.waml --substitutions=TAG_NAME=no-ip_
D
gcloud compute instances create example-instance --network custom-network1 \ --subnet subnet-us-central \ --no-address \ --zone us-central1-a \ --image-family debian-9 \ --image-project debian-cloud \ --tags no-ip
