There are a full bunch of protocols that do include addresses FTP control information for instance... For FTP when translating between v4 and v6 the NAT box has to translate commands as well as addresses... PORT <-> LPRT PASV <-> LPSV etc... > should kink such as cuseeme be left to die? Newer videoconferencing software does the same mistakes unfortunatly... H.323 for instance requires snooping of several streams to be able to translate packets. Pedro.
