Yes you can.In that event, please keep in mind, that your Router MUST be online as in most Home SetUps, the Router also works are your main and only DNS (Domain Name Service) Server.This means, if your home router is offline, Metadata Utility will keep waiting for the NAS Name response from your home Router and in that case, eventually have a time out with an error. This will happen, even if your NAS is online in your home network --unless you are an expert and have created entries in your localhost file for the necessary NAS resources--.To avoid this issue, we recommend you enter the IP Address (then Metadata Utility won't need to wait on an answer from your Router, it will simply Ping the IP Address instead).
