Hello! As reported on /., an Application Layer (Layer 7) packet filter that can block protocols regardless of port, etc. The FAQ and HOWTO are sketchy on details: I can't tell if this is more advanced than filtering packets based on the contents of the packet: something you can already easily do. Also, it's only available on 2.5, though they are working on backporting it. I thought I'd throw it out there... http://l7-filter.sourceforge.net/ Tim Massey ------------------------------------------------------- This SF.net email is sponsored by: eBay Get office equipment for less on eBay! http://adfarm.mediaplex.com/ad/ck/711-11697-6916-5 ------------------------------------------------------------------------ leaf-user mailing list: [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/leaf-user SR FAQ: http://leaf-project.org/pub/doc/docmanager/docid_1891.html
