Hi Brian, Regarding 6to4 with NAT/private addresses ... I had some time ago a different experience. But not sure right now if it was using XP with SP1 or SP2, which could make the difference.
I was using a GPRS cellular phone, via Bluetooth or infrared (not sure right now, long time ago). Then I was receiving a private address ... But 6to4 was working fine w/o any configuration from my side ! I suspected the reason for that was that the NAT was allowing protocol-41 forwarding, as described at http://www.consulintel.euro6ix.org/ietf/draft-palet-v6ops-proto41-nat-03.txt (to be updated soon) and http://www.euro6ix.org/documentation/euro6ix_co_upm-consulintel_wp4_ipv6_tun nels_nat_v1_6.pdf). It happened to me several times when traveling. I've even some screen captures, I believe ;-) Regards, Jordi > De: Brian Zill <[EMAIL PROTECTED]> > Responder a: <[EMAIL PROTECTED]> > Fecha: Thu, 17 Mar 2005 12:06:06 -0800 > Para: Michael Banta <[EMAIL PROTECTED]> > CC: <[email protected]> > Asunto: RE: 2002 addresses > > Yes, you can't use 6to4 with private addresses (at least to talk to the > rest of the Internet). 6to4 won't work to a router behind a NAT.
