    hi!

    i know i'm a noob, but i don't get this one:

    i have a comp where looknstop is installed. this one is my passage to internet. the second network card has ip 192.168.0.1. the second pc has 192.168.0.2. without looknstop the connection to internet over the second pc works.

    i need a rule which allows the second computer access to internet.

    i hope you understand what i mean. as you probably can guess, english is not my native language ;)

    thanx

    i tried the rule you mentioned, but it didn't work...

    does this one work even if i don't have look'n'stop installed on the client comp (192.168.0.2) - i only have one serial number ?

    as i said, without look'n'stop everything worked just fine...

    Yes this should work without Look 'n' Stop installed on the client computer.

    Do you have some alerts in the Look 'n' Stop log when it doesn't work ?
    If yes, could you post some of them here ?

    Thanks,

    Frederic

    Hi,

    We are investigating the same issue on the French Forum.

    It appears there is a change in the SP2 about port translation.

    What you have to do is: edit the rules containing a 1024-5000 range and change it to 1024-65535.

    A least 2 rules need to be changed:
    - "UDP : Authorize name resolution (DNS)"
    - "TCP : Authorize most common Internet services"

    If there is a way to know exactly what are the ports used by ICS on SP2, it would be better to create specific rules with the particular range (for instance 60000-62000), instead allowing all the ports.

    Has anyone any info about port translation when using ICS on XP ?

    Actually, it is also possible that there is no change in port translation, but the SP2 changed something in the network drivers that allows Look 'n' Stop now to see the packets from the clients.
    Under Windows 9x/Me, it is the case, the client packets are seen on the server and specific rules are required.

    I had the same problem with my "Streamium", it´s a Philips multimedia box that can connect through WiFi to the internet and stream radio channels.

    When i change from "5000" to "65535" in the rules u mentioned i got i to work.

    But is it safe? As long as it´s from "inside my network" and "out" i don´t mind, just hope it´s doesn´t work the other way around! ;)

    To be safer, it is possible to restrict the additional range to 60000-65000 only.
    To do that, you need to put back 5000 in the initial rules and import the rules from the following file:
    http://looknstop.soft4ever.com/Rules/XPSP2-ICS.rie

    If you are using the EnhancedRuleset, move the additional rules just near the initial ones ("TCP : XPSP2 ICS - Authorize most..." just above "TCP : Authorize most...", and "UDP : XPSP2 ICS - Authorize name..." just above "UDP : Authorize name...").
