Let me reiterate that is a NAT with no SIP or FTP ALG. Sure it was a nightmare, and continues to be a nightmare, for applications to be designed to work behind NATs but that is how applications are designed for today. I wish it was not this way but it is. The whole point of BEHAVE was to make that slightly better by providing guidance for NATs that allowed applications to make reasonable assumptions about what type of NAT environment they might have to work behind. _______________________________________________ v4v6interim mailing list v4v6interim@ietf.org https://www.ietf.org/mailman/listinfo/v4v6interim
