Control Panel → System and Security → Windows Defender Firewall → Allow an app or feature through Windows Defender Firewall

4. Click Change settings (top right), then Allow another app…

5. Add the following programs and allow them through the firewall (Private and Public if needed):

•C:\Program Files (x86)\Smart-It+ 2.0\Backend\dbserver\bin\fbserver.exe
