salve a tutti,
Grosso problema ho necessit� di bloccare il traffico netbios proveniente
dalla porta outside (wireless) sulla rete interna lan. in pratica gli
utenti che si collegano via wireless alla rete devono poter andare su
internet (e lo fanno regolarmente) ma non devono accedere alle
condivisioni della rete interna (che non ci riesco ad oggi possono vedere
tutte le condivisioni). di seguito la configurazione. grazie in anticipo a
tutti. ciao

 access-list outside_access_in permit ip any any
potresti mettere prima di questa riga dei deny.
le porte del netbios sono sia tcp che udp, ma per i numeri basta cercare 
su google. se non ricordo male, 135, 137 e 447
resta da capire il perch� dei deny dopo un "permit ip any any".
che release ha il pix?

messe così le ACL non servono a molto.. è inutile pettere un permit
any any prima dei deny, casomai devi fare il contrario! ;-)
