Configurazione firewall Cisco 827

[young]

Ho un router Cisco 827 con firewall. Ho utilizzato l’impostazione predefinita disponibile con la pagina web di configurazione e il router ha scritto questa ACL:

access-list 23 permit 192.168.0.0 0.0.0.255
access-list 102 permit ip 192.168.0.0 0.0.0.255 any
access-list 111 permit icmp any any administratively-prohibited
access-list 111 permit icmp any any echo
access-list 111 permit icmp any any echo-reply
access-list 111 permit icmp any any packet-too-big
access-list 111 permit icmp any any time-exceeded
access-list 111 permit icmp any any traceroute
access-list 111 permit icmp any any unreachable
access-list 111 permit udp any eq bootps any eq bootpc
access-list 111 permit udp any eq bootps any eq bootps
access-list 111 permit udp any eq domain any
access-list 111 permit esp any any
access-list 111 permit udp any any eq isakmp
access-list 111 permit udp any any eq 10000
access-list 111 permit tcp any any eq 1723
access-list 111 permit tcp any any eq 139
access-list 111 permit udp any any eq netbios-ns
access-list 111 permit udp any any eq netbios-dgm
access-list 111 permit gre any any
access-list 111 deny ip any any
dialer-list 1 protocol ip permit

Questa ACL consente il ping remoto e, credo, abbia lasciato attivato il protocollo Netbios. Come si può fare a modificarla in modo da disabilitare il ping e chiudere la posta Netbios? Quali comandi devo utilizzare?

[fivendra]

devi eliminare le access list del netbios e stop
se invece ne devi inserire di nuove, visto che sono gerarchiche, allora devi cancellarle tute e poi reinserirle
