<en_message>The items on one network cannot ping the items on the other network (separated by the router). Figure why and fix it. All computers and switches need fixing, but the router is OK.</en_message>
<fr_message>Les éléments d'un réseau ne peuvent pas faire de ping sur les éléments de l'autre réseau (séparés par le routeur). Figure pourquoi et réparez-le. Tous les ordinateurs et les commutateurs doivent être réparés, mais le routeur est correct.</fr_message>
