How can I use ipv6 to access website while only ipv4 is supported in my network?

Question

I'm using Ubuntu Linux as my operating system. In my network only the ipv4 is suported, and I need to access some website through ipv6. How can I do it, is there a way to tunnel from the ipv4 to ipv6.

Answer 1

there's a few options - You can use a IPV4-6 gateway such as the one provided by sixxs - the advantage of this being that you KNOW for certain its ipv6 and with almost no config . This is what i recommend IF you just need to check websites and not other internet connected resources.

While teredo - is an option - install miredo on a linux system, and ipv6 will work, with almost no config needed, but the performance is terrible compared to a proper tunnel so you're better off going with a dedicated tunnel broker - hurricane electric is what most people do, but i tend to use gogo6 - they have a client that works behind a nat, though you'd need to compile it, and configure it as per the instructions on the site.

Answer 2

If protocol 41 is open through your firewall you may be able to use a 6in4 tunnel. I used the Shorewall 6xx4 tunnels documentation to help me configure IPv6.

My tunnel is running on my OpenWRT Wifi router. I started off using the anycast address to open a tunnel, and switched to a dedicated tunnel. Latency is still higher than IPv4. My ISP still doesn't know when they will be ready for IPv6. However, I am ready for World IPv6 day.
