Is this on an unmanaged client? What OS?

You can check the traffic log but it could be because of IPv6, see this:

Traffic has been blocked for the application host process for Windows Services Svchost.exe

You're options are limited if unmanaged

  • Allow the traffic
  • Uncheck the notification
  • Turn off IPv6

See what rule is blocking the traffic.

If the rule that is blocking the traffic is "Block UPnP Discovery from external computers", then is is blcoking a network discovery traffic from a computer that is not in the local private network IP range.

To know what each default firewall policy does, check the xls in the following article.
