Exchange Hybrid - How to protect external VD access?

Hello, Lussy again.

 

When migrating from Exchange on-prem to full hybrid, all virtual directories external URLs need to be accessible for the HCW to work and the migration to be successful, correct?

 

My question is, can the external access to the virtual directories be removed/disabled, once the migration to hybrid (HCW) has completed? 

Once the migration is completed, doesn't Exchange online communicate with the on-prem Exchange via connectors?

 

Thank you.

L.
