OneIdentity Microsoft Exchange OnLine Connector

I have a customer who is asking the following question. Does anyone already know this?

"We are in the throws of setting up both the Microsoft Azure Ad connector and the Microsoft Exchange Online Connector and require confirmation of the Exchange Online Connector powershell remoting ports that will be required to be open on our boundary firewall for outbound connectivity from our On-premise Job server. I believe these will be 5985(Http) and 5986 (https), is this correct?"

Thank you,
