-----------------------+----------------------------------
I'm running Xubuntu 14.10 and OpenWrt x86 r44296 inside VirtualBox both
connected via NetworkBridge to the same router.
curl --interface ethx is not selecting the correct IPv6 address.
OpenWrt always using the ULA-Prefix. Whats going wrong inside OpenWrt IPv6
stack ?
It's not a problem of cURL Version 7.40 I also tested on 7.37 and 7.38.
Here the output of Xubuntu:
{{{
