We have a very strictly segmented network within our Active Directory domain. Server1 in Segment1 has a Remote Desktop Licensing role installed, whereas Server2 in Segment2 will have Remote Desktop Session Host role installed.
There are no other requirement considerations (i.e. internet accessibility or CRLs) and Server1 has full Domain member connectivity already. I'm not very familiar with all the features of RDS and its possibilities and I'm having a hard time finding the absolute minimum network port requirements for Server2 to retrieve its licenses from Server1 in this particular scenario.
Is it even possible to have more minimal firewall configuration besides all the default domain member ports?
