I'm trying to configure my modem-router TD-W8968 v3 for the remote access, but in the menu doesn't appear the voice "Strumenti"- "Gestione accessi" and i can't configure the port for the remote access. In the menu there is the voice "Gestione" - "Accesso remoto" but it doesn't permit the port configuration.
How can i set the port for the remote access?

thank you
