Ciao ho letto che nel web.config si possono configurare le impostazioni per l'accesso agli utenti. Se non specificato nulla laciando le configurazioni standard di dnn e in IIS lasciamo l'accesso agli utenti anonimi

Riesco a vedere il sito all'esteno della rete ma all'interno della rete dove risiede il server no.

Come posso fare devo inserire nel file di configurazione qualcosa?

vi riporto di seguito il web.config
