The problem
Port forwarding exposes a service from the internet to an internal host.
Recommended approach
Publish only the required service, restrict sources where practical and prefer VPN or secure gateways for administrative services.
Step-by-step checklist
- Identify the exact service and port.
- Create the smallest possible DNAT rule.
- Add a matching firewall policy.
- Restrict source networks when possible.
- Monitor logs after enabling the rule.
