The Simulink Real-Time product requires multiple ports and protocols to maintain connectivity between the host PC and Speedgoat target. The list of ports can vary depending on the contents and functionality implemented in the model and may change from release to release.
The following is an example of the ports the Speedgoat target uses in R2020b onwards:
- 20-23, 65532-65535, 5505-5507, 5510-5512, 5515-5517, 5555
The following is an example of the ports the Windows or Linux host PC uses in R2020b onwards:
- 20-23, 7400-7499
Possible protocols used in R2020b onwards may be:
- TCP, FTP, SSH, SCP, XCP, and RTPS/FastDDS via UDP
It is essential to allow all required ports and protocols through your firewall(s) to ensure that the Simulink Real-Time product functions correctly. Disabling any of them will result in limited functionality, so it's crucial to contact your IT department to assist in implementing the necessary rules.
Important Notes:
1) Remote access: If you intend to access a Simulink Real-Time target remotely, the ports mentioned above must be allowed through your VPN security configuration. See the following answer for more information regarding remote access to Speedgoat:
2) Firewall settings for Windows host PCs: The easiest approach is to make firewall/network exceptions for the MATLAB application (matlab.exe) and the target's IP address.
Refer to the following MATLAB Answers post for a detailed description of the steps to follow:
Additionally, we recommend adding a UDP inbound rule specific to RTPS/FastDDS traffic on ports 55**, as explained in the following answer:
3) Changing the gateway of the Speedgoat target: To ensure proper network configuration, you may need to change the gateway of the Speedgoat real-time target machine. Here are the steps to do so:
4) Further troubleshooting: If the above instructions don't help resolve the communication issues with your Speedgoat hardware, refer to this MATLAB Answer for additional troubleshooting steps:
