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. For the particular case of Windows XP, the IPv6 stack won't even attempt to create a 6to4 address from a private address.
You shouldn't need to tunnel inside your own network if it's just a single subnet. You should be able to run IPv6 natively. To do this, set up your gateway router (the machine with your end of the tunnel to your IPv6 ISP) to advertise a subnet of the prefix you get from your IPv6 ISP on your internal network, and to route IPv6 packets back and forth between your subnet and the tunnel. Any client boxes on your subnet should automatically configure addresses based on router advertisements they receive from your gateway router. --Brian > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On > Behalf Of Michael Banta > Sent: Thursday, 17 March, 2005 09:49 > To: users@ipv6.org > Subject: 2002 addresses > > Ok, things are starting to make a little more sense, thank you all. > > I was ready to assign an IP of 2002: to a windows xp client > when I realized that this machine is behind a firewall and > has a nat'ed address of 10.0.10.x.
