Ping impossible de win XP a Linux

Bonjour,
j'ai un reseau de deux PC, le 1er est sous Linux mandriva 2006 et le 2em sous windows XP,le l'ai relié par un cable croisé,
Linux a un adresse IP:192.168.0.1 et le windows:192.168.0.2.
lorsque je ping de Linux vers XP il s'effectue, et le ping de xp vers Linux ne s'effectue pas.
ou est le probleme?
merci par avance.
Configuration: Windows XP
Internet Explorer 6.0

      Salut,

      pour tester le ping tu peux desactiver le firewall
      en root tape
      shorewall stop
      --
      106485010510997108
      0
      1. merci,
        je l'ai desactivé pa "shorewall stop" mais ça n'a rien donner.
