An alias like lo:1 is*not a real device* from the kernel’s perspective;

Binding the TCP sender to lo (loopback) while connecting to a remote

logs “unable to bind.”
That's a good point. Let me try a tun device, this should be a "real" device
in linux land.
I know ip is better, but ifconfig is faster to type ;-)
