I'm trying to use a Raspberry Pi to set up as a tunnel broker via tunnelbroker.net.
I have a simple set up that looks roughly like this:
Verizon ISP Switch/IPv4 Router
|
|----- Raspberry Pi - set as DMZ Host
|----- DevLaptop
The tunnel is set up properly via the Raspberry Pi since I'm able to ping6 ipv6.google.com
I'm also able to ping the IPv6 gateway from the Raspberry Pi
I'm trying to get DevLaptop to access IPv6 networks as well via radvd on the Raspberry PI.
Even though DevLaptop is able to obtain an IPv6 address I'm not able to ping6 ipv6.google.com. I get the error message unknown host
First, here's the config on the Raspberry device.
ip -6 route show
::/96 dev sit0 proto kernel metric 256

};
Here's DevLaptop's obtained ipv6 address.
ifconfig

The only thing I'm able to do from DevLaptop is ping and get a response from the Raspberry with ping6 2001:470:1f0f:6b7::1
I wanted to do this as a weekend project to start getting familiar with IPv6 networks. Can someone point me in the right direction as to why DevLaptop is unable to reach other IPv6 networks? I was under the impression IPv6 devices would auto configure themselves after receiving a router advertisement. Is there something I'm missing?
Bonus question: My ipv6 tunnel broker is also offering a different /48 address besides the /64 address I listed above. What is the purpose of using a /48 network address versus /64?
