[RESOLVED] Armed Assault 2 (Arrowhead) Hello, I ask your attention so that you can enlighten me on one point that I can not solve with LnS. I never had a firewall until I realizes that my IP was too scanned/tested ... I therefore, on the advice of a friend, tested various software and one that caught my attention is obviously Look'n Stop. I like it a lot, but I wonder if it is necessary to acquire a license if I can not make it work properly. I tested version 2.06 and 2.07 today. (Regardless of version, I don't found what it changed). From what I understand, to allow access to my computer with some server software, I create the rules themselves into Source: PC->Net ... and if just use the software/games as a customer, I put them in Destination: PC-> Net. - With the basic rules: Everything seems to work. Except in Trackmania. Although the game starts and runs, I have constantly a message : can not find the UDP ports. I created two rules for this game using the default ports 2350-2351 and 3450-3451 1) IP-> TCP/UDP-> Destination: all IP, PORT 2350-2351 2) IP-> TCP/UDP-> Destination: all IP, PORT 3450-3451 The game seem to run.. so no really problem. Except in Armed Assault 2 (Arrowhead). The game uses ports 2302-2303 to play and 2305 for VoIP, while UDP. So I created one rule: 1) IP-> UDP> Destination: all IP, PORT 2302-2305 I hear my friends in the game, but they don't hear me. If I leave LnS, my voice going on, so there is definitely a concern with the rules ... bases or mine. I think I read in the newspaper about a redundancy rule ... block everything else. With the advanced rules: Everything seems to work ... except Trackmania and Armed Assault 2. Same reasons. With the customs rules found on the forum (phantom & others): Almost nothing works, even if I make the rules. Also I do not understand the usefulness of certain rules. The position of the rule in the list did it matter? If yes (I think), where do I put my personal rules? - Finally, I would like to know if it is not "safer" to have a single rule that blocks all and add my own rules depending on the software being used, rather than having 50 rules which are useless and even open other doors. Useless ... for my use, of course. Sorry for being long, but I was to try to be as clear as possible. Thank you for reading. Excuse my imperfect English.
