You need to set the Binding.IP property, *and* call the Binding.Bind()
method, in order to dynamically change the outbound IP of each transmission.

By itself, that will not have any effect if the Binding is already bound to
a socket. You would have to call the Binding's CloseSocket() or
AllocateSocket() method as well.

Changing the properties does not change the underlying socket automatically.
