Network ports
BMC Helix ITSM Suite consists of components that integrate with each other to support your business model. BMC Helix ITSM Suite applications use network ports for effective communication between the components.
Use the information in this topic to understand the components of a standard BMC Helix ITSM Suite and the ports used.
Using firewalls with BMC Helix ITSM Suite
A network administrator must configure firewalls correctly for effective communication between the two components. To enable communication between two endpoints, only the listening connection should be opened. Most outbound connections do not need special firewall rules to work. With more complex network designs, additional work might be needed.
Consult your network administrator to develop a plan as per your environment and confirm your configuration.
Configuring ports
Before you begin
You must consider the following factors when assigning port numbers to different processes:
- Do not assign port numbers with ports that are already in use by any other application on your system.
- Assign port numbers greater than 1024.
Ports 1-1024 are considered reserved and some clients/servers cannot use these ports for third party applications. - We recommend you to enter the desired port during the installation phase, if possible.
Configuring the ports
The AR System Server does not have default ports for all processes. You can configure the port numbers for processes of AR System Server by using the Centralized Configuration. For more information, see Setting ports and RPC numbers in the AR System documentation.
Configuring components of the client tier
The Client tier consists of client tools such as Developer Studio that help you access a service made available by a server. No client is configured for listening ports. The listening ports only connect to the server process.
All clients require the user to enter a server name or IP Endpoint to know where to direct the communications. If no port number is defined, the client will attempt to negotiate with the port mapper on the server. If the port mapper is available the client utilizes the port that is defined by port mapper. If you choose to utilize this feature, ensure the port mapper communication is available.
Refer the following image and table for information on the ports for the client tools:
Component | Description | Protocol used | Default port | Listening | Configuration parameters |
---|---|---|---|---|---|
Data Import Tool | Used for general communication to AR System Server. | TCP/ONCRPC | NA | No | TCP (On Edit Server List page) |
Developer Studio | Used for general communication to AR System Server. | TCP/ONCRPC | NA | No | TCP (On Edit Server List page) |
Web Browsers | Used for general communication to Web Tier. | TCP/HTTP(S) | 80/443 | No | NA |
Configuring components of the web tier
The Web Tier consist of web servers such as Mid Tier that enable users to access and visualize data in the BMC Helix ITSM Suite through a web browser.
If you are using a load balancer between the Web Tier application and AR System Server, you may face some problems when configuring the ports. These load balancers are commonly used in high volume and high availability environments. Consult your network administrator to configure these ports.
The following diagram shows a simplified design of the web tier. Adding additional network appliances such as load balancers, firewalls, or proxy servers will complicate the design. Consult your network administrators to configure these appliances correctly to allow appropriate communication.
Refer the following image and table for information on the ports for the web servers:
Component | Description | Protocol used | Default port | Listening | Centralized configuration parameter |
---|---|---|---|---|---|
Mid Tier HTTP(S) listener | Used to connect web browsers to the web application. | TCP/HTTP(S) | N/A | Yes | |

Configuring components of the application tier
The Application Tier computes the business logic for BMC Helix ITSM Suite and then serves to the Web Tier or the Client Tier. You do not need to identify a port for all the processes in the application tier if you use the Portmapper. For more information on Portmapper, see Setting ports and RPC numbers .

Hi, please correct the last three paragraphs. Thank you
The AR Plugin server port and the Alert Outbound Port must be greater than 1024. For detailed firewall configuration requirements for Remedy AR System, see
The page: ._brid_2NW_LinksLibrary v19.08 was not found. Please check/update the page name used in the 'multiexcerpt-include macro. in the Remedy AR system documentation.
Hello Thomas,
Thank you for reaching out! We are sorry for the issue that you faced. We have updated the topic.
Thanks,
Manash
Hi Team,
Please add communication port for new modules like New CMDB Console, RSSO, Smart Reporting, Smart IT, DWP and DWPC, so that all information will be consolidated at one place.
It would be good if we provide more information on how internal communication happens within product in ITSM suite through ports so network team can open those ports in firewall.
The diagram provided in the doc provides information for the Jetty sever (which houses the new CMDB console), RSSO, and Smart Reporting.
It doesn't include DWP or DWPC, but they would operate just like other clients like Mid-Tier, RSSO, Smart Reporting, and Smart IT.
The diagram should be used to help map out a environment. Help me understand what it is you want and I can work towards making that happen.
The chart says the shutdown port is configurable. The picture says it is not configurable. Which is correct?
Hi Scott,
Thank you for your comment on the documentation. We have updated the topic.
While the port can be configured, we do not recommend changing this setting.
Regards,
Himanshu
In ARMonitor.properties there is the line com.bmc.arsys.armonitor.RemoteObjectPort=7311 and armonitor process is listening on port 7311. Please can you document the port and clarify, wheter its needs to be opened on firewalls or not. The port is also shown in the diagram but not mentioned in table.
Good Afternoon Andreas,
Thanks for brining this to our attention. I have been working for several weeks on updating this page, I hope to have a new version published within the next few weeks which will address your concerns.
Yes the AR Monitor Remote Object port is used by AR Monitor during some of its normal everyday task and depending on your environment architecture, needs to be open for communication. Let me know if there are any questions or concerns.
Correction "Bringing"
Please can you document port 12666 aswell as its missing?
Good afternoon Andreas,
This diagram is meant to outline the daily use of AR Server. 12666 is only used during the installation, by the installer themselves. Additionally, this port should only ever be listening on the local machine, so no extra configuration is necessary, along with it being a one time only use. Lastly, this port is not able to be altered in any way (encrypted, protocol change, process change, or port number).
Because of these two facts, we made a decision to exclude this port on purpose.
Since this port needs to be open for listening, then it should be listed above even if only used during installation. Many entities are locking down system tightly. I've run into a case where if it wasn't specified to be open, it wasn't and that prevented product installation/updates.
