Except you do not get to specify that as part of the translator specification. The translator spec applies to translators, not to hosts. Translators must assume that IPv6 UDP packets with null checksum will be dropped by the receiving host. For a translator, forwarding such a packet with a null checksum is pretty much the same as dropping it. -- Christian Huitema -------------------------------------------------------------------- IETF IPv6 working group mailing list [email protected] Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
