I don't quite see the relevance of this, considering the original poster was talking about trying to differentiate "user initiated" traffic from unwanted traffic. I pointed out this was impossible with some protocols and cited PORT mode FTP as one example.
See RFC3027 for information regarding protocol limitations with NAT.
Thanks, but I'm well aquanted with the pro's and con's of NAT, I've been using it in various forms for years, and I'm quite familiar with the operation of "protocol helpers" like the ones that any NAT device worth its salt has for PORT mode FTP...
