Ports used in Configuration Manager
This article lists the network ports that Configuration Manager uses. Some connections use ports that aren't configurable, and some support custom ports that you specify. If you use any port filtering technology, verify that the required ports are available. These port filtering technologies include firewalls, routers, proxy servers, or IPsec.
If you support internet-based clients by using SSL bridging, in addition to port requirements, you might also have to allow some HTTP verbs and headers to traverse your firewall.
Ports you can configure
Configuration Manager enables you to configure the ports for the following types of communication:
- Enrollment proxy point to enrollment point
- Client-to-site systems that run IIS
- Client to internet (as proxy server settings)
- Software update point to internet (as proxy server settings)
- Software update point to WSUS server
- Site server to site database server
- Site server to WSUS database server
- Reporting services points
Note You configure the ports for the reporting services point in SQL Server Reporting Services. Configuration Manager then uses these ports during communications to the reporting services point. Be sure to review these ports that define the IP filter information for IPsec policies or for configuring firewalls.
By default, the HTTP port that's used for client-to-site system communication is port 80, and 443 for HTTPS. You can change these ports during setup or in the site properties.
Non-configurable ports
Configuration Manager doesn't allow you to configure ports for the following types of communication:
- Site to site
- Site server to site system
- Configuration Manager console to SMS Provider
- Configuration Manager console to the internet
- Connections to cloud services, such as Microsoft Azure
Ports used by clients and site systems
The following sections detail the ports that are used for communication in Configuration Manager. The arrows in the section title show the direction of the communication:
- --> Indicates that one computer starts communication and the other computer always responds
- Indicates that either computer can start communication
Asset Intelligence synchronization point --> Microsoft
| Description | UDP | TCP |
|---|
| HTTPS | -- | 443 |
Asset Intelligence synchronization point --> SQL Server
| Description | UDP | TCP |

| SQL over TCP | -- | 1433 Note 2 Alternate port available |
Client --> Client
Wake-up proxy also uses ICMP echo request messages from one client to another client. Clients use this communication to confirm whether the other client is awake on the network. ICMP is sometimes referred to as ping commands. ICMP doesn't have a UDP or TCP protocol number, and so it isn't listed in the below table. However, any host-based firewalls on these client computers or intervening network devices within the subnet must permit ICMP traffic for wake-up proxy communication to succeed.

Notes for ports used by clients and site systems
Note 1: Proxy server port
This port can't be configured but can be routed through a configured proxy server.
Note 2: Alternate port available
You can define an alternate port in Configuration Manager for this value. If you define a custom port, use that custom port in the IP filter information for IPsec policies or to configure firewalls.
Note 3: Windows Server Update Services (WSUS)
Since Windows Server 2012, by default WSUS uses port 8530 for HTTP and port 8531 for HTTPS.
After installation, you can change the port. You don't have to use the same port number throughout the site hierarchy.
- If the HTTP port is 80, the HTTPS port must be 443.
- If the HTTP port is anything else, the HTTPS port must be 1 or higher, for example, 8530 and 8531.
Note When you configure the software update point to use HTTPS, the HTTP port must also be open. Unencrypted data, such as the EULA for specific updates, uses the HTTP port.
- Add non-clustered indexes to the WSUS database to improve WSUS cleanup performance
- Remove obsolete updates from the WSUS database
If you change the default SQL Server port to an alternate port with SQL Server Configuration Manager, make sure the site server can connect using the defined port. Configuration Manager doesn't support dynamic ports. By default, SQL Server named instances use dynamic ports for connections to the database engine. When you use a named instance, manually configure the static port.
Note 4: Trivial FTP (TFTP) Daemon
The Trivial FTP (TFTP) Daemon system service doesn't require a user name or password and is an integral part of Windows Deployment Services (WDS). The Trivial FTP Daemon service implements support for the TFTP protocol that's defined by the following RFCs:
- RFC 1350: TFTP
- RFC 2347: Option extension
- RFC 2348: Block size option
- RFC 2349: Time-out interval and transfer size options
TFTP is designed to support diskless boot environments. TFTP Daemons listen on UDP port 69 but respond from a dynamically allocated high port. If you enable this port, the TFTP service can receive incoming TFTP requests, but the selected server can't respond to those requests. You can't enable the selected server to respond to inbound TFTP requests unless you configure the TFTP server to respond from port 69.
The PXE-enabled distribution point and the client in Windows PE select dynamically allocated high ports for TFTP transfers. These ports are defined by Microsoft between 49152 and 65535. For more information, see Service overview and network port requirements for Windows.
However, during the actual PXE boot, the network card on the device selects the dynamically allocated high port it uses during the TFTP transfer. The network card on the device isn't bound to the dynamically allocated high ports defined by Microsoft. It's only bound to the ports defined in RFC 1350. This port can be any from 0 to 65535. For more information about what dynamically allocated high ports the network card uses, contact the device hardware manufacturer.
Note 5: Communication between the site server and site systems
By default, communication between the site server and site systems is bi-directional. The site server starts communication to configure the site system, and then most site systems connect back to the site server to send status information. Reporting service points and distribution points don't send status information. If you select Require the site server to initiate connections to this site system on the site system properties after the site system has been installed, the site system won't start communication with the site server. Instead, the site server starts the communication. It uses the site system installation account for authentication to the site system server.
Note 6: Dynamic ports
Dynamic ports use a range of port numbers that's defined by the OS version. These ports are also known as ephemeral ports. For more information about the default port ranges, see Service overview and network port requirements for Windows.
Other ports
The following sections provide more information about ports that Configuration Manager uses.
Client to server shares
Clients use Server Message Block (SMB) whenever they connect to UNC shares. For example:
| Description | UDP | TCP |
|---|
| Server Message Block (SMB) | -- | 445 |
Connections to SQL Server
For communication to the SQL Server database engine and for intersite replication, you can use the default SQL Server port or specify custom ports:
- Intersite communications use:
- SQL Server Service Broker, which defaults to port TCP 4022.
- SQL Server service, which defaults to port TCP 1433.
When you use Azure and the site database is behind an internal or external load balancer, configure the following components:
- Firewall exceptions on each replica
- Load-balancing rules
Configure the following ports:
- SQL over TCP: TCP 1433
- SQL Server Service Broker: TCP 4022
- Server Message Block (SMB): TCP 445
- RPC Endpoint Mapper: TCP 135
Configuration Manager doesn't support dynamic ports. By default, SQL Server named instances use dynamic ports for connections to the database engine. When you use a named instance, manually configure the static port for intrasite communication.
The following site system roles communicate directly with the SQL Server database:
- Certificate registration point role
- Enrollment point role
- Management point
- Site server
- Reporting Services point
- SMS Provider
- SQL Server --> SQL Server
When a SQL Server hosts a database from more than one site, each database must use a separate instance of SQL Server. Configure each instance with a unique set of ports.
If you enable a host-based firewall on the SQL Server, configure it to allow the correct ports. Also configure network firewalls in between computers that communicate with the SQL Server.
For an example of how to configure SQL Server to use a specific port, see Configure a server to listen on a specific TCP port.
Discovery and publishing
Configuration Manager uses the following ports for the discovery and publishing of site information:
- Lightweight Directory Access Protocol (LDAP): 389
- Secure LDAP (LDAPS, for signing and binding): 636
- Global catalog LDAP: 3268
- RPC Endpoint Mapper: 135
- RPC: Dynamically allocated high TCP ports
- TCP: 1024: 5000
- TCP: 49152: 65535
External connections made by Configuration Manager
On-premises Configuration Manager clients or site systems can make the following external connections:
- Asset Intelligence synchronization point --> Microsoft
- Endpoint Protection point --> internet
- Client --> Global catalog domain controller
- Configuration Manager console --> internet
- Management point --> Domain controller
- Site server --> Domain controller
- Site server Issuing Certification Authority (CA)
- Software update point --> internet
- Software update point --> Upstream WSUS Server
- Service connection point --> Azure
- Service connection point --> Azure Logic App
- CMG connection point --> CMG cloud service
Installation requirements for site systems that support internet-based clients
This section only applies to internet-based client management (IBCM). It doesn't apply to the cloud management gateway. For more information, see Manage clients on the internet.
Internet-based management points, distribution points that support internet-based clients, the software update point, and the fallback status point use the following ports for installation and repair:
- Site server --> Site system: RPC endpoint mapper using UDP and TCP port 135
- Site server --> Site system: RPC dynamic TCP ports
- Site server Site system: Server message blocks (SMB) using TCP port 445
Application and package installations on distribution points require the following RPC ports:
- Site server --> Distribution point: RPC endpoint mapper using UDP and TCP port 135
- Site server --> Distribution point: RPC dynamic TCP ports
Use IPsec to help secure the traffic between the site server and site systems. If you must restrict the dynamic ports that are used with RPC, you can use the Microsoft RPC configuration tool (rpccfg.exe). Use the tool to configure a limited range of ports for these RPC packets. For more information, see How to configure RPC to use certain ports and how to help secure those ports by using IPsec.
Before you install these site systems, make sure that the remote registry service is running on the site system server and that you have specified a site system installation account if the site system is in a different Active Directory forest without a trust relationship. For example, the remote registry service is used on servers running site systems such as distribution points (both pull and standard) and remote SQL Servers.
Ports used by Configuration Manager client installation
The ports that Configuration Manager uses during client installation depends on the deployment method:
- For a list of ports for each client deployment method, see Ports used during Configuration Manager client deployment
- For more information about how to configure Windows Firewall on the client for client installation and post-installation communication, see Windows Firewall and port settings for clients
Ports used by migration
The site server that runs migration uses several ports to connect to applicable sites in the source hierarchy. For more information, see Required configurations for migration.
Ports used by Windows Server
The following table lists some of the key ports used by Windows Server.
| Description | UDP | TCP |
