It's more like missing feature, not any bug. AFAIK it was never implemented in route(8) to set IPv6 address as a next hop for IPv4 network. It should be possible to do it with Linux iproute2 package under Linux emulation though. Anyway, without options NETLINK or netlink.ko module loaded it won't be possible as rtsock interface doesn't support that. Cheers -- Marek Zarychta
