Description
Inbound traffic is allowed to a resource from any source instead of a restricted range.
How to fix?
Set source_ranges to specific IP range only, e.g. 192.168.1.0/24.
Example Configuration
resource "google_compute_firewall" "allowed" {
name = "test-firewall"
network = "default"
direction = "INGRESS"
allow {
protocol = "icmp"
}
allow {
protocol = "tcp"
ports = ["80", "8080", "1000-2000"]
}
source_ranges = ["192.168.0.0/24"]
}
