@hashiz any clue why it would try to bind address B with the WAN interface? is there something conflicting in the routing table which makes it believe this to be possible?

I would actually like to see the config, a log file with --verb 4 and understand why it's having an interface ID there that is not valid.
Always setting the ifindex to 0 might work in this case, but in the generic case we use the ifindex the OS gives to us, so that is what we need to use.
Maybe it's just an OS bug (we've found a few, in various OSes).
