And i cannot to use "debedit" for setup the properties, so...with FP2 is not possible...realy? loop -----Mensaje original----- De: Mailing list for discussion of Firewall-1 [mailto:[email protected]]En nombre de Laidlaw, Rob Enviado el: miércoles, 24 de septiembre de 2003 16:08 Para: [email protected] Asunto: Re: [FW-1] p2p in NG FP2 You cannot stop them by ports alone. They will just morph to use other ports. AI has code that will look into http packets looking for messenger and p2p apps, but in order for that to work, the p2p apps have to use port 80. For that to happen, and this is checkpoints design recommendations, is that you restrict your workstations to only a few services that are needed. Like port 80 can go anywhere, because AI will look into the packets to find p2p. Other services that may be needed like telnet or ftp should be restricted to only certain machines or only certain destination subnets if possible. If you leave ftp open to anywhere, the p2p app will use it and ai won't be able to find the p2p app to stop it. You basically need an almost air tight security policy for your work stations which doesn't always go over well with users/managers. There are third party apps that are more robust like L7 from akonix, but they will cost you a little bit and require hardware to run on. They still have design requirements. Good luck.
