Handled in the 6to4 and Teredo specs. The router returns a reverse NAT for the browser to respond to which it rewrites and then forwards.

At least, I hope so. I don't think that will work. 1. Browser is instructed to go www.example.com 2. DNS returns only an IPv6 address record (AAAA) for that site 3. Browser computer has only IPv4 connectivity 4. Now what? The browser cannot plug an IPv6 address into the IPv4 stack. ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected] with the body: unsubscribe ntsysadmin
