    try disabling TCP SPI in options. it could also be your rules.

    i just switched to shareaza. it uses teh G1 and G2 networks and it works fine with looknstop.

    Hi arneevillar :)

    You have to create TESTS rules to collect samples in the log and find which ports are used by this program.

    1- add Limewire in the application filter (no restrictions for ports and addresses)

    2- create a TEST rule TCP/UDP with no retrictions for this application

    3- place this rules immediatly after the rule blocking the incommings TCP Packets + SYN flag (the "Central rule" )

    4- repeat this procedure but now place the second TEST rule immediatly before the rule blocking the incommings TCP packets + SYN flag

    5- enable the logging (including raw logging in the advanced options)

    6- save and reboot your PC

    7- use Limewire for a ± long period of time to collect samples in the log:

    You'll see that only the first TEST rules, the one placed immediatly before the rule blocking incomming TCP packets + SYN is taked in account...

    8- disable the TEST rule placed before the "Central rule" :

    You'll see now some blocked access: this is exactly what we need!

    The port(s) correspondings to the blocked ones are used for the server part of Limewire so you have to create a rule to give the access to this(those) local port(s) for the "Server" part of this application... (access to your shared folder in your PC to the other PCs in this p2p network)

    For sure the blocked access are included in the access logged with the first TEST rule ... (not the other blocked access such the one to port 135 for example...)

    You'll see also that this time the second TEST rule is now taked in account and log in/out access. These entries shows the ports used by the "Client" part of Limewire to access the other PCs in this p2p network...

    9- Stop Limewire, close your internet connection and check the log.

    10- Look in C:\Program Files\Soft4Ever\looknstop\logs you'll find a raw log with a name like raw07312006.log.

    Copy this file and change the extension .log to .txt: raw07312006.txt

    11- Used MS Excel or OO Calc (or any spreadsheet program) and import this "raw07312006.txt" as .csv file (comma separated file) into a spreadsheet.

    This way you may keep only the line you need:
    line from the TEST1 rule, TEST2 rule and blocked access
    and sort the data to see which ports are used by the application.
    From this you can create rules for Limewire and check again until evethings is fine...

    The raw log format is this:

    * A- Date
    * B- Hour in UTC
    * C- "UTC"
    * D- D = Download or U = Upload
    * E- 1 = autorised or 0 = blocked
    * F- Sequence number of the entry in the log
    * G- Rule's name:
    * H- Ethernet Type 800 = IPV4
    * I- Size of packets
    * J- IP Source
    * K- IP Destination
    * L- Protocol number: 6 = TCP, 17 = UDP
    * M- Source port
    * N- Destination port

    Keep only these columns: D, E, J, K, L, M, N. You may sort the data using destination port as sort criteria.

    Remember that a P2P programm have a "client" part such as any other application AND a "Server" part which allow other PCs to initiate a connection to your PC. The first rules (the ones for client) must be placed after the "Central rule", the others: the "Server" rules must be placed before the "Central rule"...

    If you understand french you may check these articles about this question (including screen captures):



    and this post about the "Server/Client" question (post #5)

    Hope this help. Let us know.

    For some information on setting Limwire up with a firewall, check this page on the official homepage. You'll need to open the port listed in the settings on your computer to allow traffic in by adding a rule to Internet Filtering.
