Are you talking about to open port to VM on Azure ?

Here is good step-by-step tutorial how to open web trafic on Azure

you don't need to play with windows firewall

U need to create azure network security group (NSG) and latch it to your VM

NSG contains all inbound and outbound rules and can be applied to multiple VMs
U need to define rules at NSG level
