La configurazione del protocollo ipv4 č corretta, č come la tua con i dns di google ma con assegnazione automatica dell'indirizzo ip.
Probabilmente č qualche porta chiusa, non saprei quale. Proverņ a telefonare all'assistenza TIM.
EDIT: č praticamente impossibile contattare la TIM
Ho dato il comando netstat -a e ho ottenuto queste porte qua:
