Is there a limit to the number of access restrictions?
There is a limit of 512 access restriction rules. If you require more than 512 access restriction rules, we suggest that you consider installing a standalone security product, such as Azure Front Door, Azure App Gateway, or an alternative WAF. Follow the procedure as outlined in the preceding section, but with the following addition:
What does it mean to restrict access to an Azure service?
Therefore, access restrictions are effectively network ACLs. The ability to restrict access to your web app from an Azure Virtual Network (VNet) is called service endpoints. Service endpoints enable you to restrict access to a multi-tenant service from selected subnets.
How are from addresses evaluated in Microsoft Access restriction list?
When a request is made to your app, the FROM address is evaluated against the rules in your access restriction list. If the FROM address is in a subnet that’s configured with service endpoints to Microsoft.Web, the source subnet is compared against the virtual network rules in your access restriction list.
Can a service endpoint restrict access to an app?
With service endpoints, you can restrict access to a multi-tenant service from selected subnets. It doesn’t work to restrict traffic to apps that are hosted in an App Service Environment. If you’re in an App Service Environment, you can control access to your app by applying IP address rules.
How does access restrictions work in Microsoft Azure?
You can use access restrictions to define a priority-ordered list of IP addresses that are allowed or denied access to your app. The list can include IPv4 and IPv6 addresses, or specific virtual network subnets using service endpoints. When there are one or more entries, an implicit “deny all” exists at the end of the list.
Can you allow or block access to websites?

If the FROM address is in a subnet that is configured with service endpoints to Microsoft.Web, then the source subnet is compared against the virtual network rules in your access restrictions list.
