6to4 tunnel is done wrong.

[Wenger X]

IPv6 6to4 tunnel is done completely off 6to4 standards and works only with native IPv6 hosts. If remote host is on 6to4, packets will be dropped, because of wrong routing and tunnel settings.

With regards to

eval("ip", "-6", "route", "add", "2000::/3", "via", ip, "dev", tun_dev, "metric", "1");

aren’t you making an overzealous assumption based on current IP6 addressing plans? Shouldn’t you be adding a “default” route instead?
