If the ping and software update succeed but the connection from MATLAB fails with one of the above errors, it is likely that incoming UDP traffic is blocked. This issue specifically affects ports used by the RTPS/FastDDS protocol. To address this, create a UDP-specific inbound rule in Windows Defender Firewall. Coordinate with your IT team to follow these steps:
Option 1: Create Inbound UDP Rule using PowerShell (recommended)
Start Windows PowerShell as an administrator and run the following command:
New-NetFirewallRule -DisplayName "Speedgoat" -Direction Inbound -RemotePort 5505-5507,5510-5512,5515-5517 -Protocol UDP -Action Allow -Profile Any -RemoteAddress <SpeedgoatIPaddress>
Replace <SpeedgoatIPaddress> with your device's IP address (e.g., 192.168.7.1), or use an IP range/subnet if you wish to connect to multiple targets. If you prefer not to specify an IP address, use 'Any' for the -RemoteAddress flag, or omit it entirely.

Option 2: Create Inbound UDP Rule using Windows Defender Firewall GUI
Alternatively, implement the rule in the Windows Defender Firewall GUI as shown below:
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:
