Port Requirements for WinRM authentication

These ports are used for Windows Remote Management (WinRM) authentication, enabling successful remote access and management of Windows servers.

Port Name	Port Number	Protocol	Usage	Connection
HTTPS port	5986	TCP	Secure port used for encrypted WinRM communication between the DDI Central Management UI Console and the Windows server.	Inbound
HTTP port	5985	TCP	Non-encrypted port used for WinRM communication between the DDI Management UI Console and the Windows server.	Inbound

DDI Central Application Specific Port Requirements

These ports are specific to DDI Central, handling web-based management, database communication, and real-time updates.

Port Name	Default Port Numbers	Protocol	Usage	Connection
Web server port	9090	TCP	Provides access to the DDI Central Management UI Console via a web browser, enabling users to configure and manage DDI services	Inbound
Embedded database port	33306	TCP	Enables communication with the embedded PostgreSQL database used by DDI Central for data storage and retrieval	N/A
HTTPS Port	9443	TCP	Used by DDI Central's Management UI console to securely connect with Windows DNS/DHCP server(s), ensuring encrypted communication for monitoring and management tasks.	Inbound
Web Socket	8001	TCP	Enables real-time updates and live monitoring between DDI Central and connected servers.	Bidirectional

Database Requirements

PostgreSQL comes bundled with the product.

Note: In case of failover, please use PostgreSQL with replication configured.

Network Port Configurations

To ensure optimal performance and seamless operation of DDI Central on your Windows environment, the following network port configurations are required:

DNS (Domain Name System)

TCP and UDP Port 53: Must be open for DNS query and response traffic. DNS uses this port for both TCP and UDP protocols to handle standard query and response action, as well as zone transfers (TCP).

DHCP (Dynamic Host Configuration Protocol)

UDP Port 67 (Primary DHCP): Must be open for receiving DHCP discovery requests from DHCP clients.This is the standard port on which the DHCP server listens for and responds to DHCP discovery messages and other requests from clients.
TCP Port 647 (DHCP Failover): Must be open to enable communication between primary and secondary DHCP servers in a failover configuration. This port is used for synchronization of DHCP lease information and other configuration data to ensure continuity and consistency of DHCP services in case one of the servers becomes unavailable.

These port configurations are essential to allow the DDI system to communicate effectively within your network infrastructure. Ensure that any firewalls or network security systems are configured to permit traffic on these ports for the DDI solution's components.
