There's another feature of NAT that is desirable that has not yet been mentioned, and which at least some customers may be cognizant of: the fact that NAT is a pretty restrictive firewall. I'm as big a fan of the end-to-end principle as anybody, but until the ends are trustworthy, we can't get there. Whether by IPv6 or IPv4, less-than-fanatically-administered Windows and Unix systems simply cannot be directly connected to the Internet. :( -- Chris Palmer Staff Technologist, Electronic Frontier Foundation 415 436 9333 x124 (desk), 415 305 5842 (cell) 81C0 E11D CE73 4390 B6C7 3415 B286 CD8F 68E4 09CD
