Sapete se il MAP-E presenta lo stesso tipo di incapsulamento del post precedente su wireshark?
Perché così su due piedi, tra il DHCPv6 che non fornisce i parametri per il MAP, e i capture che sono riuscito a fare mostrano tutti dei pacchetti con incapsulamento IPIP ("[Protocols in frame: eth:ethertype:vlan:ethertype:ipv6:ip:udp:data]" e "Next Header: IPIP (4)")

ipotizzerei che nel mio caso la connessione sia in ipipv6 e non in MAP-E... Possibile?
Dopo tanta fatica a tirare su e configurare la vm openwrt, esce fuori che sono sul protocollo che non è supportato e per il quale non ci sono (a quanto no visto cercando) moduli installabili... 😃
C'è di buono che se è effettivamente così, non dovrei aver bisogno di particolari parametri, gli indirizzi per ipip6 credo siano facilmente recuperabili dalla trace, sono gli stessi in tutti i pacchetti.
Mi sfugge solo dov'è che viene negoziato tra iliadbox e ONT il fatto di usare quel tipo di tunnel, visto che non ve n'è traccia nella trace dei pacchetti.
