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:

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.
