Options to hide Service Bis Queues ot Topics from Public Internet?

Hello,

I am fully aware that I can secure Service Bus Queues and Topic with Shared Access Policy keys. I am seeking for other options.

In case we are dealing with security sensitive Azure Service Bus queues and Topics, Is there any option to hide the Service Bus Queues and Topic from the public internet and limit the access to a few Worker roles in Azure Data center?

Also, can we limit the access to a few IP addresses?

Thank you,
