   Table 1 Parameter description

   Parameter	Description
   Forwarding Protocol	Specifies the protocol used to forward user service workload. tcp: TCP is a connection-oriented protocol that provides reliable delivery of a stream of bytes at the transport layer. udp: UDP is a connectionless protocol that provides simple transaction-oriented delivery of messages at the transport layer.
   Forwarding Port	Specifies the port used to forward user service workload.
   Origin Server Port	Specifies the port used by the origin server.
   Origin Server IP Address	Specifies the public IP address used by the origin server. After configuring the rules, change the domain names based on your services. AAD will automatically forward traffic to your origin server IP addresses. You can add a maximum of 20 origin server IP addresses. Separate them with commas (,). Enter a valid public IP address.
