Hello all
Babel through Openvpn is working if I give ipv6 to tun0 and if Openvpn is point to point.
But, if I want use Openvpn through babeld, it doesn't work.
may be because address range is not /24?
I use two Ip range: 10.50.1.0 for wireless and 10.50.0.0 to avoid conflicts between ahcpd and dhcpd
this some log and config:
when I launch Openvpn through Babel on Wifi: (it can't add 88.XXX.XXX.XXX/32 via 10.50.1.3)

-------------------
If I use wire (eth0), and dhcp server (it give me inet 10.50.0.195/24 brd 10.50.0.255 )
openvpn work, but it doesn't use babel to reach default route (given by dhcp server).
Openvpn log: (it can add 88.XXX.XXX.XXX/32 via 10.50.0.2 )

(at this time I don't gived link local ipv6 to tun0 yet, and not restarted ahcpd)
thanks to help me using Openvpn through Babel :p
