Bonjour c'est mon premier post sur ce forum.
Excuses pour mon manque de compréhension du réseau
mais Im annonce à apprendre.
J'ai un problème pour atteindre la passerelle par défaut 10.18.110.1

Si j'utilise mon portable je peux ping 10.18.110.1 mais avec notre chapeau rouge de la passerelle multi-serveur ne répond pas au ping.
cat / etc / redhat-release
Red Hat Enterprise Linux ES release 3 (Taroon Update 6)

Alors II pense que c'est un problème de routage mais je ne peux pas dire si les ci-dessous est correct ou non.

J'avais un ami d'un coup d'oeil et il a pensé la table de routage est okey.

Toutes les suggestions sont les bienvenues.
