Almost two years ago I described testing IPv6 using Freenet6 on FreeBSD. This morning I decided to try the same on Windows XP and document the process here.
I needed to use a tunnel method like Freenet6 because the test host is behind NAT.
First, visit go6.net and click "Free IPv6 Connectivity with Freenet6". Register yourself a user account. To install on my Windows XPSP3 32-bit system I downloaded "Gateway6 Client 6.0-BETA4 Windows Installer 32-bit". I installed and accepted the defaults:
When I first tried installing the software I got an error which denied installing the TUN driver. I had to back out of the installation and change this local group policy key using gpedit.msc:
I changed "Do not allow installation" to "Warn but allow installation" under Local Computer Policy -> Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> Security Options -> Devices: Unsigned driver installation behavior.
Once The Freenet6 client was running I configured it with the username and password I registered, and I set broker.freenet6.net as my Gateway6 address. Once I connected I could visit ipv6.google.com, and even check my IPv6 address online.
You may notice I installed the ShowIP Firefox addon. I learned about that from Command Information. It's a good way to try to keep track of the IP address you're using to access IPv4 or IPv6 sites.
I was also able to access sites from cmd.exe, using ping6 to ping ipv6.google.com and ftp to connect to the IPv6-only FTP server at ftp6.netbsd.org.
I think the Freenet6 client is a good way for people behind NAT (or in the case of the test VM here, two NATs) to access IPv6-enabled sites.
