To ensure smooth host-target communication when using Simulink Real-Time R2020b or later, it is important to consider the configuration of the host PC Ethernet interface. If the interface is set to 'Public', disruptions in communication may occur.
One potential solution is to configure the host PC Ethernet interface used for the host-target link as 'Private'. Our documentation provides detailed instructions on how to achieve this:
However, many organizations have strict IT policies that prevent users from changing the network type to 'Private'. In such cases, the configuration may revert back to 'Public' after a period of time or following a PC restart.
To address this challenge, we recommend implementing the following Inbound rule in Windows Defender Firewall instead. We advise involving your IT helpdesk to assist you with this process:
1. Find "Windows Defender Firewall with Advanced Security" by using the Windows search:
2. Create a new custom inbound rule:
3. Allow UDP connections from remote ports 5505-5507, 5510-5512, 5515-5517:
4. Optionally, for enhanced security and to restrict the rule's scope, consider adding the Speedgoat's remote IP address:
5. Ensure that the rule applies to all three network types (Domain, Private, and Public) as illustrated below:
However, you can configure the firewall by using the following command in Windows Powershell. Please replace the 'SpeedgoatIPaddress' with your Speedgoat IP address.
New-NetFirewallRule -DisplayName "Speedgoat" -Direction Inbound -LocalPort 5505-5507,5510-5512,5515-5517 -Protocol UDP -Action Allow -Profile Any -RemoteAddress <SpeedgoatIPaddress>
