 # Tutorial: Filter inbound Internet or intranet traffic with Azure Firewall policy DNAT using the Azure portal
 
-You can configure Azure Firewall policy Destination Network Address Translation (DNAT) to translate and filter inbound Internet or intranet (preview) traffic to your subnets. When you configure DNAT, the *rule collection action* is set to **DNAT**. Each rule in the NAT rule collection can then be used to translate your firewall public or private IP address and port to a private IP address and port. DNAT rules implicitly add a corresponding network rule to allow the translated traffic. For security reasons, the recommended approach is to add a specific source to allow DNAT access to the network and avoid using wildcards. To learn more about Azure Firewall rule processing logic, see [Azure Firewall rule processing logic](rule-processing.md).
