## Feature Coverage
### Network Configuration ✅
- Physical interface configuration (IP, zone, MTU, admin state)
- VLAN interface creation and management
- DHCP server configuration with reservations and custom options
- DNS forwarder configuration
- Static route management
### Security & Firewall ✅
- Layer 3/4 firewall rules with zone-based filtering
- Rule ordering control (top, bottom, position)
- Common baseline rules applied fleet-wide
- Per-firewall custom rules
### VPN ✅
- **Site-to-Site IPsec VPN**
- Phase 1 (IKE) configuration
- Phase 2 (IPsec) configuration
- Dead Peer Detection (DPD)
- NAT traversal support
- **Remote Access VPN**
- SSL VPN configuration
- User group authentication
- 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
## Version History
