# API Reference: Implementing GCP VPC Firewall Rules
|
|
|
|
## Libraries
|
|
|
|
### google-cloud-compute
|
|
- **Install**: `pip install google-cloud-compute`
|
|
- **Docs**: https://cloud.google.com/python/docs/reference/compute/latest
|
|
|
|
### Key Classes and Methods
|
|
|
|
| Class | Method | Description |
|
|
|-------|--------|-------------|
|
|
| `FirewallsClient` | `list(project)` | List all firewall rules |
|
|
| `FirewallsClient` | `get(project, firewall)` | Get rule details |
|
|
| `FirewallsClient` | `insert(project, firewall_resource)` | Create rule |
|
|
| `FirewallsClient` | `patch(project, firewall, firewall_resource)` | Update rule |
|
|
| `FirewallsClient` | `delete(project, firewall)` | Delete rule |
|
|
| `NetworksClient` | `list(project)` | List VPC networks |
|
|
|
|
### Firewall Rule Object Fields
|
|
- `name` -- Rule name (unique per project)
|
|
- `network` -- VPC network path
|
|
- `direction` -- `INGRESS` or `EGRESS`
|
|
- `priority` -- 0 (highest) to 65535 (lowest)
|
|
- `allowed[]` -- Protocol and port combinations to allow
|
|
- `denied[]` -- Protocol and port combinations to deny
|
|
- `source_ranges[]` -- Source CIDR ranges for ingress
|
|
- `destination_ranges[]` -- Destination CIDRs for egress
|
|
- `target_tags[]` -- Network tags to apply rule to
|
|
- `source_tags[]` -- Source instance tags
|
|
- `disabled` -- Boolean to disable without deleting
|
|
- `log_config.enable` -- Enable firewall rule logging
|
|
|
|
## Priority Ranges (Best Practice)
|
|
- 0-999: Emergency/override rules
|
|
- 1000-9999: Organization policies
|
|
- 10000-49999: Application-specific rules
|
|
- 50000-64999: Default deny rules
|
|
- 65534: Implied allow egress (GCP default)
|
|
- 65535: Implied deny ingress (GCP default)
|
|
|
|
## gcloud CLI Equivalents
|
|
- `gcloud compute firewall-rules list`
|
|
- `gcloud compute firewall-rules create NAME --allow tcp:22 --source-ranges 10.0.0.0/8`
|
|
- `gcloud compute firewall-rules delete NAME`
|
|
- `gcloud compute firewall-rules update NAME --disabled`
|
|
|
|
## Hierarchical Firewall Policies
|
|
- Organization-level: `compute.firewallPolicies`
|
|
- Folder-level: Applied via `compute.firewallPolicies.addAssociation`
|
|
- Evaluation order: Organization > Folder > VPC rules
