The path is only a gbit switch and for the Wifi a Wifi access point in bridge mode. There is no firewall on the server and on one of the clients.

The behaviour of the two clients is the same. _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
