 This article provides steps to configure a container group in a [virtual network](container-instances-virtual-network-concepts.md) integrated with a [Network Address Translation (NAT) gateway](../virtual-network/nat-gateway/nat-overview.md). By configuring a NAT gateway to SNAT a subnet address range delegated to Azure Container Instances (ACI), you can identify outbound traffic from your container groups. The container group egress traffic will use the public IP address of the NAT gateway. A single NAT gateway can be used by multiple container groups deployed in the virtual network's subnet delegated to ACI.

 Deploy the following sample container into the virtual network. When it runs, it sends a single HTTP request to `http://checkip.dyndns.org`, which displays the IP address of the sender (the egress IP address). If the application rule on the firewall is configured properly, the firewall's public IP address is returned.
