Only allow Google Load Balancer traffic (Firewall Rules)

For security reasons you should only allow incoming traffic from Google Load Balancer on your backend instances. To do so, when making a GCE firewall rule, just set the Source IP ranges to these GCE IPv4 ranges:

130.211.0.0/22
35.191.0.0/16
