This is a significant security consideration as:
Required actions:
🔗 Analysis chainVerify firewall rules for the NAT setup. The NAT configuration looks good, but ensure that appropriate firewall rules exist to:
Let me check the content of the found file to see if it contains any relevant network configuration or TODOs. Let me check if there are any other Terraform files in the networking module that might contain firewall rules. 🏁 Scripts executedThe following scripts were executed for the analysis: Script: #!/bin/bash
# Check for existing firewall rules in the Terraform configs
rg -l "google_compute_firewall" .
# Look for any network-related TODO comments
rg -l "TODO.*network|firewall|egress|ingress" .

🛠️ Refactor suggestion
Enhance NAT configuration with security and performance settings.
The current NAT configuration uses the most permissive settings which might not be optimal for production:
ALL_SUBNETWORKS_ALL_IP_RANGES
if not all instances need internet access📝 Committable suggestion

I don't think this will work as the pod ip's are 10.32.x.x

@zacharyblasczyk, understood. Thank you for pointing that out—the pod IPs being in the 10.32.x.x range means the suggested NAT configuration changes may not be appropriate here. Please disregard my earlier suggestion.
