- Common baseline rules applied fleet-wide
- Per-firewall custom rules

### VPN ✅

  - IP address pool management
  - Split tunnel support
  - DNS and routing for VPN clients

### Web Application Firewall (WAF) ✅
- Backend server configuration
- Protection policy management
- Virtual host/web policy configuration
- Exception/allow-list management
- **Baseline import functionality** (export from one firewall, apply to fleet)

### Management & Monitoring ✅
- Device access policies (HTTPS, SSH, SNMP, ping)
- SNMP configuration (v2c/v3, community strings, trap destinations)
- Syslog server configuration
- NTP time synchronization

## Key Design Features

### 1. Idempotency
All operations are designed to be safely re-runnable:
- API state checking before modifications
- `changed_when` conditions on all tasks
- Proper handling of create vs. update operations

### 2. Baseline Import System
Unique feature for WAF configuration:
- Export WAF config from baseline firewall via API
- Transform to structured YAML variables
- Commit to version control
- Apply as fleet-wide defaults
- Allow per-firewall overrides

### 3. Production-Ready
- Ansible Vault support for credentials
- Comprehensive error handling
- Retry logic for API calls
- Timeout configuration
- No-log for sensitive data
- Serial execution control

### 4. CI/CD Integration
- Check mode for dry-runs
- Tagging system for partial deployments
- Example GitLab CI configuration
- Ansible-lint and yamllint configurations

### 5. Comprehensive Documentation
- README with full usage guide
- QUICKSTART for rapid deployment
- Inline comments in all playbooks and roles
- Example configurations with realistic data

## Usage Examples

### Deploy Full Configuration
```bash
ansible-playbook -i inventory/hosts.ini site.yml
```

### Deploy to Specific Firewall
```bash
ansible-playbook -i inventory/hosts.ini site.yml --limit fw-branch1
```

### Deploy Specific Components
```bash
# Network only
ansible-playbook -i inventory/hosts.ini site.yml --tags network

# VPN only
ansible-playbook -i inventory/hosts.ini site.yml --tags vpn

# WAF only
ansible-playbook -i inventory/hosts.ini site.yml --tags waf
```

### Baseline Import Workflow
```bash
# 1. Export baseline WAF config
ansible-playbook -i inventory/hosts.ini baseline_import.yml

# 2. Review generated config
cat inventory/group_vars/baseline_web.yml

# 3. Commit to version control
git add inventory/group_vars/baseline_web.yml
git commit -m "Update baseline WAF configuration"

# 4. Apply to fleet
ansible-playbook -i inventory/hosts.ini site.yml --tags waf
```

### Secure Credentials
```bash
# Encrypt host variables
ansible-vault encrypt inventory/host_vars/fw-branch1.yml

# Run with vault password
ansible-playbook -i inventory/hosts.ini site.yml --ask-vault-pass
```

## Variable Schema

Complete variable documentation available in separate schema document. Key variable types:

- **Network**: `sophos_interfaces`, `sophos_vlans`, `sophos_dhcp_servers`, `sophos_dns`, `sophos_static_routes`
- **Firewall**: `sophos_firewall_rules`, `sophos_common_firewall_rules`
- **VPN**: `sophos_site_to_site_vpns`, `sophos_remote_access_vpn`
- **WAF**: `sophos_waf_backends`, `sophos_waf_policies`, `sophos_waf_virtual_hosts`, `sophos_waf_exceptions`
- **Management**: `sophos_common_device_access_policies`, `sophos_snmp`, `sophos_logging`, `sophos_ntp`

## Testing & Quality

### Linting
- ansible-lint configuration included
- yamllint configuration included
- Skips appropriate false-positives

### Sample Configurations
- fw-baseline: Baseline firewall with DMZ
- fw-branch1: Branch with site-to-site VPN, VLANs, DHCP options
- fw-branch2: Branch with remote access VPN
- fw-sample1: Minimal test configuration

### Validation
- Pre-flight connectivity checks
- Required variable validation
- API authentication testing
- Firmware version compatibility warnings

## Deployment Scenarios

### Scenario 1: New Firewall Fleet
1. Define inventory in `hosts.ini`
2. Create host_vars for each firewall
3. Run full site.yml deployment
4. Verify with check mode first

### Scenario 2: Existing Fleet with WAF
1. Define baseline firewall in inventory
2. Run baseline_import.yml to export WAF config
3. Review and commit baseline_web.yml
4. Deploy to remaining firewalls with site.yml

### Scenario 3: Incremental Updates
1. Modify specific variables in host_vars
2. Use tags to deploy only changed components
3. Use --limit to target specific firewalls
4. Review changes with --check first

### Scenario 4: CI/CD Pipeline
1. Commit changes to Git
2. CI pipeline validates with ansible-lint
3. CI runs check mode for preview
4. Manual approval required
5. CD applies changes to production

## API Integration

### Sophos XGS API
- Uses XML-based API via HTTPS
- Default port: 4444 (management interface)
- Authentication: Username/password or API key
- All operations via `uri` Ansible module
- XML templates in Jinja2 for all API calls

### Error Handling
- HTTP status code validation
- XML response parsing
- Retry logic with configurable delays
- Timeout protection
- Graceful failure modes

## Security Considerations

### Credentials Management
- Ansible Vault integration
- No-log for sensitive tasks
- Separate credentials per firewall
- Support for both password and API key auth

### Network Security
- API access over HTTPS only
- Certificate validation (configurable)
- Device access policies to restrict management
- Rate limiting via serial execution

### Audit Trail
- All changes logged by Sophos XGS
- Ansible execution logs
- Commit history in Git
- CI/CD pipeline logs

## Maintenance & Support

### Regular Maintenance Tasks
1. Update baseline WAF configuration monthly
2. Review firewall logs for errors
3. Rotate credentials quarterly
4. Update Ansible collections
5. Test in lab before production deployment

### Troubleshooting Resources
1. README.md troubleshooting section
2. Role task files (detailed comments)
3. Template files (show API structure)
4. Ansible verbose mode (-vvv)
5. Sophos XGS API documentation

## Future Enhancements

Potential additions for future versions:
- SD-WAN configuration
- Application control policies
- IPS signature management
- Certificate management
- User authentication (LDAP/RADIUS)
- High availability (HA) configuration
- Backup and restore automation
- Custom report generation
- Webhook integrations
