Hi Liviu, I'm not intimately familiar with PPP on Win7, but what you describe sounds broken to me. I'd suggest getting in touch with Chris Palmer about this, he's with Microsoft(you'll find his e-mail address in the list archives). For what it's worth, if you're using IPv6 over 3GPP mobile broadband, you get an entire /64 to play with - not only the single interface identifier assigned by the network using PCO (which is bridged into IPV6CP when using PPP). The only requirement is that you use the network-provided interface identifier when constructing the link-local address - no such restriction is placed on the choice of global address. 464XLAT is one example of a technology that uses more than 1 address from the assigned /64, so the behaviour you describe would make it impossible to implement 464XLAT on Win7 for users using 3G dongles in PPP mode.
