In a NORMAL session type, invalid is any address/port couple other than the original server socket address.
In an ANY-PORT session type, invalid is any host other than the original server.
In an ANY-SOCK session type, invalid is any address/port couple other than the server socket address from which the first reply came.

The datagram is ignored.
