Explanation:
To minimize the risk of SNAT port exhaustion for your 100 virtual machines in subnet4-1, while ensuring minimal administrative effort, you can use an Azure NAT Gateway. This service provides scalable and resilient outbound connectivity for virtual networks, dynamically allocating SNAT ports to avoid exhaustion.
* Navigate to the Azure Portal.
* Search for "NAT gateways" and select it.
* Click on "Create".
* Enter the following details:
* Subscription: Select your subscription.
* Resource Group: Select an existing resource group or create a new one.
* Name: Enter a name for the NAT gateway (e.g., NATGateway-Subnet4-1).
* Region: Select the region where your virtual network is located.
* Click on "Next: Outbound IP".
* Choose whether to use existing public IP addresses or create new ones.
* If creating new ones, click on "Add new" and configure the new public IP addresses.
* Click on "Next: Subnet".
* Click on "Associate subnet".
* Select the virtual network that contains subnet4-1.
* Select subnet4-1 from the list of subnets.
* Click on "OK".
* Review your settings to ensure everything is correct.
* Click on "Review + create" and then "Create".
* Azure NAT Gateway: This service provides outbound connectivity for virtual networks, dynamically allocating SNAT ports across all VM instances within a subnet. This dynamic allocation helps prevent SNAT port exhaustion, especially in scenarios with high outbound connection volumes12.
* Dynamic SNAT Port Allocation: Unlike static allocation methods, NAT Gateway dynamically allocates SNAT ports based on demand, ensuring efficient use of available ports and reducing the risk of exhaustion2.
