Implement Password Hash Synch - list exactly URLs need to allow on firewall Sophos UTM

Hi,

My company is using firewall Sophos UTM, guideline below recommend that I should open all in MS documented URLs, so it is to many host need open, it is impossible for me open a lot of hosts one by one on my firewall

https://docs.microsoft.com/en-us/azure/active-directory/hybrid/how-to-connect-install-prerequisites

I only need Password hash sync & write back password features. Can I get exact URLs that I need to allow for these?

Thanks,
