Hi all,
I have to limit internet navigation of a specific machine (eg. 192.168.0.2).

Can anyone help me?
Thanks a lot

name: limit pc
source: ip address of that pc
dest: any
service: any
action: deny
log: packets

This rule will block all traffic from the specific pc (ip address). If that pc is allowed to use FTP only add a second rule and make sure its above the rule 'limit pc'. Rules are checked from top to bottom.

name: ftp only
source: ip address of that pc
dest: any
service: FTP
action: allow
log: connections
translation: NAT (default outgoing interface)

If that pc is allowed only access to a specific FTP server replace the 'dest: any' part with 'dest: ip address of ftp server'.

Always remember that rules are checked from top to bottom. If KWF finds a rule that matches it applies that rule. So if you put the rule 'limit pc' above the rule 'ftp only' the firewall will block ftp traffic because the request of the client matches the rule 'limit pc'. KWF will not look at other rules because it has a match.

To see what is happening check the filter log and the connection log.

thank you,
I suspected this but I would explain my situation:
we have rules for all the users and only admin can navigate free over internet.
A user know admin pwd (even if we change it) and use it to navigate.
I would limit his machine only to respect our rules even if he use admin login.
Can I obtain this?

Thanks very much
(sorry my poor english)

Yes.

Make a rule for that specific machine and put it above the other rules. In that rule you specify what traffic is allowed from that ip address. In that case the password is not significant because its not used.
