    Да, это сделано. В итоге traceroute6 выглядит так:
    $ traceroute6 ipv6.google.com
traceroute6 to ipv6.l.google.com (2a00:1450:4001:c02::69) from 2001:1af8:4101:4::1:2, 64 hops max, 12 byte packets
 1  2001:1af8:4101:4::1  79.862 ms  40.280 ms  38.412 ms

    Т.е. дальше сервера запрос не уходит.
    tcpdump на сервере такой:

    # tcpdump  -i tap0 -v ip6
