Time required: 2 Hours
In this lab, you will apply Network Security Group (NSG) rules to a subnet containing a virtual machine running nginx. You will see how a predefined rule that blocks inbound traffic prevents internet connections to that VM; how adding a rule with a smaller priority number allows public connections; how the statefulness of NSG-controlled connections affects the processing of inbound and outbound rules; and how reordering inbound rule priorities affects connectivity.
This lab will be entirely conducted in the Azure portal, via a Web browser.
