The Ford Draft is quite liberal in its statements regarding issues with NAT. Unfortunately, in the real-world, those examples are somewhat fewer and farther between than the draft RFC would lead you to believe. Considering how many end-users sit behind NAT firewalls and non-firewall gateways at home, at work, and at public access points all day without issue, this is a particularly good example of the IETF's ongoing issues with design-by-committee, particularly committees short on security engineering and long on special interest. While LECs and ISPs may or may not feel some pain from LSN, they're equally sure feel better after crying all the way to the bank. IMO, Roger Marquis
