Configure Azure Firewall ports required to join Domain Controller

Problem

There are two virtual networks, Network 1 (contains Domain Controller, Windows Server 2016) and Network 2 (contains workload VMs, Windows Server 2016). Traffic between them goes through Azure Firewall and User Defined Routes.

Solution

After some experiments came up with following categories of rules:

Name	Proto	Src	Dest	Ports
tcp-to-dc	tcp	*	<dc server>	53,88,135,139,389,445,464,3268,3269,49152-64000
udp-to-dc	udp	*	<dc server>	53,88,123,135,137,138,464,389,49152-64000
