As a matter of fact the first version of my reply did mention clientAddr
but then I looked in the code and saw that we are setting
client_addr.sin_port to 0, and that kills any address binding.

If I remember correctly the purpose of clientAddr really is to bind to a
certain interface, not to bind to a certain port.
