    Hi @Nishanali E.V.T ,

    You'll find all the required ports listed over at the official documentations below:

    How to configure a firewall for Active Directory domains and trusts
    https://learn.microsoft.com/en-us/troubleshoot/windows-server/identity/config-firewall-for-ad-domains-and-trusts

    Service overview and network port requirements for Windows
    https://learn.microsoft.com/en-us/troubleshoot/windows-server/networking/service-overview-and-network-port-requirements

    It is also possible to hard-code the port that is used for Active Directory replication by following the steps in here:
