[LARTC] TOS for IPv6 traffic in a tunnel

[LARTC] TOS for IPv6 traffic in a tunnel

Hi!

I searched the internet but did not find any results yet. Maybe here is
someone that might help me.

Is it possible to use the traffic class of an IPv6 packet to set the TOS
value of a wrapping IPv4 packet, that will transport the IPv6 packet
through a tunnel?

I am asking this because I want to extend the traffic classes I am using
on my DSL link to also classify IPv6 packets correctly that are routed
through a tunnel over this DSL link.

Another question: Is it possible that ssh/scp set the traffic class of
IPv6 packets? The class seems to be 0x00 for both applications while
with IPv4 connections I see different ToS values for both.


Thank you!
    Matthias
