IPv6 and default routes
March 5, 2010
Following on from my first tutorial, we have a box set up which has basic IPv6 connectivity. There’s a firewall in place with a simple but sufficient configuration. And we can ping6 from this box to remote IPv6 destinations.
All of this has, so far, made use only of one network interface (in my case eth0) to set things up. However looking ahead to the next step I am aware that I will want devices inside my network (i.e. my workstations, etc.) to have IPv6 connectivity through this device I am setting up. In other words, this device must, as it does today for IPv4, act as a router.
With IPv4 this is, at a basic level (so forgetting about firewalling and so on) very easy: enable IPv4 forwarding and away you go.
For IPv6? A little more complicated…
