Partage connexion wifi mandriva

Bonjour,
J'ai eu un problème avec mon firewall et shorewall pour être plus précis. Je partage ma connexion internet via une carte wifi pci en mode ad-hoc. Pas de problème jusqu'à que j'ouvre un port sur shorewall. Plus possible de relancer shorewall. :

J'ai donc voulu reprendre la manip du début et la c'est le drame. dans l'outil de configuration "partage de connexion" de mandriva il me dit que je n'ai pas de carte configuré et pourtant :

# iwconfig

C'est vraiment à n'y rien comprendre.

Merci de votre aide.
