ReadyNAS RND2000 v2 Accesso ad interfaccia amministratore locale

I guess better communicate in English!

Well I am facing unaccessibie  local administrator page.

Nas actually connected cascading on a switc/router with static IP.

The Nas has been resetted to intial condition and OS reinstalled. It shows two predefined folders.

It is visible if scanned in the lan, how ever is not possible to access as administrator.

The scope is to transfer on it folders to be shared by three PC's in network. So far I am not sure it will fullfill my scope.

Any suggestion ? Thanks
