Read Only DC

[rafi]

Hello~  I have a RODC in a location and users authenticate to it at that location.  I want to make sure traffic is not blocked when RODC needs to communicate to DC at HQs.  Firewall is not blocking outbound traffic but I am getting started in making sure that is filter.  Does anyone know what tcp/udp ports I need to have in the firewall rule to allow this traffic?  Thanks.

Heaps of different ports.  So many I would just allow the two AD's to have full IP address to each other.

Thank you.  I did come up with a list from Microsoft here. In case you are curious.
