I don’t see how this is an IETF issue. Push pn the vendor to fix it; or don’t buy it.

YEs, a problem with software that runs on a particular hardware problem.

Another problem with that software too, is that it is closed source and a very high price to buy.  Moreover, it is almost forbidden to modify it by other company than the writer.

Very many people were tempted to fix that software but it looks very hard to access.

How can it be a hardware problem?  Bits are bits. Don't you mean "a problem with software that runs on a particular hardware platform?"

           They dont understand that nobody asks them to implement
           DHCPv6 on the modem.  The DHCPv6 happens between ARM and the

           (the 'modem') blocks 547.
           That's the problem.
       I'm confused.   I thought you were saying that we can't do ND,
       but it sounds like what we can't do is DHCP.   And the reason we
       can't do it is a misconfigured middlebox, not a protocol issue.
   I was saying the DHCPv6+ND is unsolved in cellular.  It is not a
   protocol issue but a hardware problem.
   There are protocol solutions to the hardware problems, like ability
   to vary port numbers.
   Or we can further wait for hardware issues to be solved, if ever.
