Blocking wireless hosts through PIX

Hello,
      Here is the situation. I have PIX firewall and a couple of switches behind the firewall and a Wireless Router. The wireless router has an IP of 10.1.1.23. There are a few hosts which use the wireless router to connect to the internet. My question is that one of the hosts which connect to the wireless router has an IP address of 10.1.1.253, and I would like to know how I can write an ACL that will block this IP address from accessing the internet, without blocking the 10.1.1.23 wireless router access to the internet. The wireless router is just acting as an Access Point nothing else no DHCP is running etc, and that’s how I would like to leave it.


                                                                           Thank You,
                                                                          Victor

Victor,

  Do you have any acls on your inside interface ? If so, add this to it;

access-list <Name> deny ip 10.1.1.253 any

and then apply it to the 'inside' interface.

Cheers,
Rajesh

Hi,

 Shouldn't the access-list be "access-list deny_outbound deny ip host 10.1.1.253 any" ?

Yeah, if it is a single host then you can go by that specific host.

Victor,
Don't forget to add the permit any any at the end. If you don't, the implicit "deny all" will take over.

access-list deny_outbound deny ip host 10.1.1.253 any
access-list deny_outbound permit ip any any

access-group deny_outbound in interface inside
