The Simulink Real-Time target uses multiple ports to communicate and exchange essential information with the host. This is required for full normal functionality.
The list of ports will vary depending on the contents and functionality implemented in the model and will change from release to release. You may consider allowing these ports through your firewall or VPN security configuration if you intend to access a Simulink Real-Time target remotely:
The following is an example of the ports the target uses in R2020b onwards:
20-23, 65532-65535, 5505-5507, 5510-5512, 5515-5517, 5555
Possible used protocols in R2020b and beyond may be: FTP, SSH, and RTPS/DDS via UDP
