I have just started too learn about IPv6 and i must say it is really interesting.
I have managed to set up a simple Local area network with two hosts, and they are able to communicate using the local-link address. This isn't that difficult since Ubuntu comes with IPv6 pre-configured and all i really had two do was to ping the other machine.
Were ethx is the network interfaces from which i send my ping.
But that's link-local, what i want to do next is to set static IPv6 addresses on my hosts. So that i can choose which address they should be using.
So i edited /etc/network/interfaces in the following way:
I have set a static ip on both of the hosts, but to be able to ping each other i have to uncomment this line: #net.ipv6.conf.all.forwarding=1
iface eth0 inet static
pre-up modprobe ipv6
I'm just wondering, is this the "correct" way of setting up a IPv6 LAN with static ip's? The part that confuses me is that i must uncomment the line in /etc/sysctl.conf
grateful for all the answers
