How to: Activate Service Broker Networking (Transact-SQL)
Service Broker does not send or receive messages over the network by default. To activate Service Broker networking in an instance, create an endpoint for Service Broker.
Creating a Service Broker endpoint causes SQL Server to accept TCP/IP connections on the port specified. Service Broker transport security allows you to require authorization for connections to the port. If the computer that runs SQL Server has a firewall enabled, the firewall configuration on that computer must allow both incoming connections for the port specified in the endpoint. For more information on Service Broker transport security, see Service Broker Transport Security.
