As a p2p lover, I encountered problems tweaking Look'n'Stop to work well with emule (kad open). The problem is that emule kad generated a lot of fragmented UDP packets in both directions (in and out), which are taken as threaten and are blocked by Look'n'Stop (phant0m's rule set, and normal emule's rull of course). In emule forum this has been discussed, one of amule developers, Kry, said it's bad to block those fragmented UDP packets because it's how kad works. I'm quite confused about security and getting full function of emule kad. I've written my own rule to let fragmented UDP packets go through when emule is running (hope I'm not doing stupid thing). I wonder if there's better rules sets that can do the same without degrade the security. For example, take UDP fragments packets if it's from the ip whose first packets is send to the port of emule UDP listening port. Is it possible? Thanks for your help.
