 The IP firewall rules are applied at the Service Bus namespace level. Therefore, the rules apply to all connections from clients using any **supported protocol** (AMQP (5671) and HTTPS (443)). Any connection attempt from an IP address that doesn't match an allowed IP rule on the Service Bus namespace is rejected as unauthorized. The response doesn't mention the IP rule. IP filter rules are applied in order, and the first rule that matches the IP address determines the accept or reject action.
 
 ## Important points
-- Virtual Networks are supported only in the **premium** tier of Service Bus. If upgrading to the **premium** tier isn't an option, it's possible to use IP firewall rules using the [portal](#use-azure-portal), [Azure Resource Manager templates](#use-resource-manager-template), [Azure CLI](#use-azure-cli), [PowerShell](#use-azure-powershell) or [REST API](#rest-api). We recommend that you keep the Shared Access Signature (SAS) token secure and share it with only authorized users. For information about SAS authentication, see [Authentication and authorization](service-bus-authentication-and-authorization.md#shared-access-signature).

 - Specify **at least one IP firewall rule or virtual network rule** for the namespace to allow traffic only from the specified IP addresses or subnet of a virtual network. If there are no IP and virtual network rules, the namespace can be accessed over the public internet (using the access key).  
 - Implementing firewall rules can prevent other Azure services from interacting with Service Bus. As an exception, you can allow access to Service Bus resources from certain **trusted services** even when IP filtering is enabled. For a list of trusted services, see [Trusted services](#trusted-microsoft-services).
