    Hello.
    During work with Exchange-server MS Outlook demands ports 1024-5000 on both sides. If make rule - all is good. But if Outlook to set a range 1024-5000 in Applications filter, the port 1177 is thrown out and connection with a server is impossible. This port (UDF Archive server) is registered in possible trojan, but why it is thrown out? If to enter 1177;1024-5000, the port is authorized and connection will be. What can be a problem?
    Thanks.

    PS: Sorry for bad English...

    Add: MS Outlook and 1177 port

    APP: TCP port not allowed

    Hi,

    Are you configuring Look 'n' Stop on the server side or on the client side ?

    On the client side, normally you just need to specify the destination ports, like 110 & 25, but not the local source ports like 1024-5000.

    Regards,

    Frederic

    Have you added Outlook (application) to the rule that you created? The "Application" button is at the bottom left; when creating a rule click this button to add the applications that start this rule.

    Hello, Frederic

    Look 'n' Stop is configured on the client side.
    Outlook works with MS Exchange through RPC port (135) and RPC Communication ports (1024-5000):

    Ethernet type - IP
    Protocol - TCP
    Application - MS Outlook
    Directions - both
    Other parameters - default
    Adrresses/ports - My_computer:1024-5000 <-> Exchange_server:135;1024-5000


    If to make for Outlook two rules, Email works without problems:

    My_computer:1024-5000 <-> Exchange_server:135
    My_computer:1024-5000 <-> Exchange_server:1024-5000
    Applications - MS Outlook (ports are not set)



    If to set Outlook ports 135;1024-5000 in the Applications Filtering Page, port 1177 is blocked:

    Internet Filtering Page rule for Outlook:
    My_computer:1024-5000 <-> Exchange_server:All_ports
    Applications Filtering Page:
    MS Outlook with TCP ports 135;1024-5000

    If enter 135;1177;1024-5000 port 1177 is not blocked.


    I don't understand...

    Hi ArtLonger,

    There is a problem for some port range selection, in the application filtering.

    Could you try the following update:
    http://looknstop.soft4ever.com/Beta/lnsfw1/LNSFW1-d2.zip

    - rename c:\winnt\system32\drivers\lnsfw1.sys in lnsfw1.old
    - unzip the new driver in c:\winnt\system32\drivers
    - reboot the computer.

    Thanks,

    Frederic

    Yes, this driver (3.04 d2) is the last beta. This means it includes the leaktest detection enhancements.
