Azure Network Interface NAT Rule Association
This page shows how to write Terraform and Azure Resource Manager for Network Interface NAT Rule Association and write them securely.
azurerm_network_interface_nat_rule_association (Terraform)
The Interface NAT Rule Association in Network can be configured in Terraform with the resource name azurerm_network_interface_nat_rule_association
. The following sections describe 10 examples of how to use the resource and its parameters.

Explanation in Terraform Registry
Manages the association between a Network Interface and a Load Balancer's NAT Rule.
Tips: Best Practices for The Other Azure Network Resources
In addition to the azurerm_network_security_group, Azure Network has the other resources that should be configured for security reasons. Please check some examples of those resources and precautions.
azurerm_network_security_group
Ensure to disable RDP port from the Internet
It is better to disable the RDP port from the Internet. RDP access should not be accepted from the Internet (*, 0.0.0.0, /0, internet, any), and consider using the Azure Bastion Service.
azurerm_network_security_rule
Ensure to set a more restrictive CIDR range for ingress from the internet
It is better to set a more restrictive CIDR range not to use very broad subnets. If possible, segments should be divided into smaller subnets.
azurerm_network_watcher_flow_log
Ensure to enable Retention policy for flow logs and set it to enough duration
It is better to enable a retention policy for flow logs. Flow logs show us all network activity in the cloud environment and support us when we face critical incidents.
Microsoft.Network/loadBalancers/inboundNatRules (Azure Resource Manager)
The loadBalancers/inboundNatRules in Microsoft.Network can be configured in Azure Resource Manager with the resource name Microsoft.Network/loadBalancers/inboundNatRules
. The following sections describe how to use the resource and its parameters.
Example Usage from GitHub
An example could not be found in GitHub.
Parameters
name
required - stringtype
required - stringapiVersion
required - stringproperties
requiredfrontendIPConfiguration
requiredid
required - stringResource ID.
protocol
required - stringThe reference to the transport protocol used by the load balancing rule.
frontendPort
required - integerThe port for the external endpoint. Port numbers for each rule must be unique within the Load Balancer. Acceptable values range from 1 to 65534.
backendPort
required - integerThe port used for the internal endpoint. Acceptable values range from 1 to 65535.
idleTimeoutInMinutes
optional - integerThe timeout for the TCP idle connection. The value can be set between 4 and 30 minutes. The default value is 4 minutes. This element is only used when the protocol is set to TCP.
enableFloatingIP
optional - booleanConfigures a virtual machine's endpoint for the floating IP capability required to configure a SQL AlwaysOn Availability Group. This setting is required when using the SQL AlwaysOn Availability Groups in SQL server. This setting can't be changed after you create the endpoint.
enableTcpReset
optional - booleanReceive bidirectional TCP Reset on TCP flow idle timeout or unexpected connection termination. This element is only used when the protocol is set to TCP.
Frequently asked questions
