-This article describes how to secure outbound traffic from your applications hosted in Azure Spring Apps. The article provides an example of a user-defined route (UDR). A UDR is an advanced feature that lets you fully control egress traffic. You can use a UDR in scenarios such as disallowing an Azure Spring Apps autogenerated public IP address.

 Azure automatically routes traffic between Azure subnets, virtual networks, and on-premises networks. If you want to change the default routing in Azure, create a route table.
 
 The following example shows how to create a route table to be associated with a specified subnet. The route table defines the next hop, as in the Azure Firewall instance that you created. Each subnet can have one route table associated with it, or it might have no associated route table.
