I am afraid there is no 3GPP modem for smartphone that lets DHCPv6 through. Qualcomm blocks multicast UDP 547 whereas Balong blocks multicast altogether. I do need a modem to connect on 4G, LTE-V2X and pre-5G that does let DHCPv6 through. But I would like to ask you: if no such modem exist on the market, why not modifying the DHCPv6 protocol to work on non-547 ports and on unicast?
