    Bonjour,

    J'ai 2 PC enréseau (cable croisé) sous WinXPpro, le serveur est connecté à internet par un modem USB, le second PC accede à internet via le serveur.
    LnS 2.04 est installé sur les 2 PCs.
    Surle serveur, pas de prob, lorsque je lance une nouvelle appli qui accede au net, j'ai une alerte.
    Par contre coté client car je n'ai aucune alerte lorsque une application essaye d'accéder à internet, malgré le fait que le filtrage soit actif. J'ai comme interface réseau la carte eth.

    Une idée ?

    Salut R.R!

    Est-ce que tu as configuré tes ordinateurs comme il faut? Le FAQ l'explique comme c'est écrit ci-dessous (excuse-moi que c'est en anglais, mais le site français ne marche pas pour le moment):

    Is Look 'n' Stop compatible with ICS (Internet Connection Sharing)

    Yes, Look 'n' Stop is compatible with ICS.

    Look 'n' Stop must be installed on the server PC and the client PC(s). The Server PC is directly connected to the Internet. The client PC is connected to the Internet through the server PC. ICS is installed on the server PC.

    http://www.soft4ever.com/LooknStop/En/images/faq_ics_2pcs.gif

    The server has 2 IP address. The first one allows to identify the server on the "external" Internet network. The other address allows to identify the server on the "internal" local area network (LAN).
    The example 1 also applies to Ethernet card ADSL connections and to Ethernet card cable connections. In those cases, the USB port of the server is replaced by and Ethernet card.

    http://www.soft4ever.com/LooknStop/En/images/faq_ics_3pc_hub.gif

    A crossover Ethernet cable is not sufficient to connect 3 or more PCs. A Hub allows to connect PCs together. In this example, the IP address of the server on the local network is 192.168.0.1 and the IP address of the client PCs are 192.168.0.2 and 192.168.0.3. More than 3 PCs can be connected on a hub, depending on the number of ports available on the hub (4, 8, 16, 32, ...).

    How to configure Look 'n' Stop for ICS (Internet Connection Sharing) ?

    The Look 'n' Stop configuration is made very easy thanks to rules import/export.

    On the server PC, import the RulesImportDefaut.rie rules from the Internet filtering tab, select the ICS_server rule and click the Import button.

    Important (Windows© 2000 or XP) : if the server is under Windows© 2000 or XP,
    the Look 'n' Stop default ruleset that applies after the installation is sufficient. There is no need for a specific ICS server rule if you did not remove rules from the standard ruleset.

    On the client PC, import the RulesImportDefaut.rie rules from the Internet filtering tab, select the ICS_client rule and click the Import button.

    ___________

    You can also decide to create the rules 'manually'

    Look 'n' Stop on the ICS server
    1 : Select the Internet Filtering page
    2 : Click on the Add button
    3 : In the Rule Name zone, type "ICS server"
    4 : In the Direction zone, click on "Internet >> PC and PC >> Internet"
    5 : In the Ethernet Type zone, Select IP
    6 : In the Source (PC >> Net) / Destination (Net >> PC) zone, in the IP address area, select 'Mask' and just below enter 192.168.0.0 , and below again enter 255.255.255.0.
    7: Click on OK. The Rule appears at the top of the list. You can leave it there.
    8 : Uncheck (suppress) the Stop sign () to allow the Rule to the ICQ program to exchange data.
    9 : Click on Apply

    Look 'n' Stop on the ICS clients
    1 : Select the Internet Filtering page
    2 : Click on the Add button
    3 : In the Rule Name zone, type "ICS client"
    4 : In the Direction zone, click on "Internet >> PC and PC >> Internet"
    5 : In the Ethernet Type zone, Select IP
    6 : In the IP zone, position Protocol on ICMP
    7 : In the ICMP zone, set ICMP code equal to 4
    8 : In the ICMP zone, set ICMP type equal to 3
    9 : Click on OK. The Rule appears at the top of the list. You can leave it there.
    10 : Uncheck (suppress) the Stop sign () to allow the Rule to the ICQ program to exchange data.
    11 : Click on Apply

    Par contre le filtrage devrait fonctionner... Est-ce que tu as vraiment choisi la carte eth. correcte? Est-ce que tu as d'autres possibilités?

    Salutations!

    Je suis exactement dans la configuration n°1

    Ayant Windows XP sur le serveur, je n'ai pas touché la config standard, j'ai juste ajouté la regle ICS Client sur le pc client.
    J'ai essayé d'interdire un logiciel (e-mule) pour voir si le blocage se faisanit, mais ca ne passe pas.
    J'ai Norton Antivirus 2003 sur le PC Client, ca peut jouer ?
