I'm not about to put a 2.5 kernel in my router. I doubt it works for protocols like FTP as it uses regular expressions to identify the protocol much like a virus program. The data connection of FTP might not have any identifying data... A good way of doing that would be a plugin system, in which such plugins could interpret the protocol. Maybe some kind soul will backport it to 2.4 so i can test it :)
