From what I know, Stateful Packet Inspection (SPI) is merely a way to maintain a constant connection. It prevents incoming packets from being spoofed and allows FTP connections. Is it also used to maintain torrent connections? From a security standpoint, I don't think it is worth the risk since SPI allows you to bypass your firewall rules. Furthermore, according to Wikipedia, you're web browser can be forced to solicit outside connections just by viewing malicious websites. Is Wikipedia correct in this allegation? It would be much appreciated if I could some how get a hold of Look N Stop version 2.06 and its md5 check sum. Thanks!
