I use connman but get no  Scope:Global IPV6 address.
What so I miss ?

Thanks
PC

Simply enabling tethering for ethernet technology will cause ethernet
to use the online service as its upstream via NAT masquerading and join
ethernet into the 'tether' bridge. The latter option is nice as now all
tethered devices will be able to connect each other, independent
whether connected over Bluetooth, WiFi or ethernet. DHCP and DNS will
be shared between all the tethered technologies as DHCP and DNS open
their sockets on the bridge interface.

If your network wlan0 is not configured for IPv6, there won't be any
Router Advertisments and thus ConnMan cannot configure global
addresses.

If you know the network is configured with IPv6, check that
/proc/sys/net/ipv6/conf/wlan0/disable_ipv6 returns 0,
/proc/sys/net/ipv6/conf/default/accept_ra is 1 and that there are no
firewall rules eating IPv6 packets.

'connmanctl config wifi_XXXX ipv6 auto preferred' should restore
address autoconfiguration to sane values.


Cheers,

        Patrik
