The documentation clearly indicates that a Bastion host can be used with a DevTest Lab. However, I have not seen any documentation indicating whether it can be used with a Classroom Lab. Is this possible? There are many scenarios where students can't get to the virtual machines because of port restrictions. The Bastion host would get around this problem. If the Bastion host is not possible, is there another way to configure a classroom lab to allow access via a well-known port like 443?
