An IP address based access control rule is a custom WAF rule that allows you to control access to your web applications by specifying a list of IP addresses or IP address ranges in Classless Inter-Domain Routing (CIDR) form.

By default, your web application is accessible from the internet. If you want to limit access to your web applications only to clients from a list of known IP addresses or IP address ranges, you need to create two IP matching rules. First IP matching rule contains the list of IP addresses as matching values and set the action to "ALLOW". The second one with lower priority, is to block all other IP addresses by using the "All" operator and set the action to "BLOCK". Once an IP restriction rule is applied, any requests originating from addresses outside this allowed list receives a 403 (Forbidden) response.

1. Install the [Azure CLI](/cli/azure/install-azure-cli), or use the Azure Cloud Shell. The Azure Cloud Shell is a free Bash shell that you can run directly within the Azure portal. It has the Azure CLI pre-installed and configured to use with your account. Select the **Try it** button in the CLI commands that follow. Selecting **Try it** invokes a Cloud Shell that you can sign in to your Azure account with. Once a cloud shell session starts, enter `az extension add --name front-door` to add the front-door extension.
