-This example is a simple deployment of Azure Firewall. For advanced configuration and setup, see [Tutorial: Deploy and configure Azure Firewall and policy by using the Azure portal](../../firewall/tutorial-firewall-deploy-portal-policy.md). You can associate an Azure firewall with a network address translation (NAT) gateway to extend the extensibility of source network address translation (SNAT). A NAT gateway can be used to provide outbound connectivity associated with the firewall. With this configuration, all inbound traffic uses the public IP address or addresses of the NAT gateway. Traffic egresses through the Azure firewall public IP address or addresses.  For more information, see [Scale SNAT ports with Azure Virtual Network NAT](../../firewall/integrate-with-nat-gateway.md).
