That's the thing Mark, configuring it is where I'm stuck. I'm unsure of what addresses I'm supposed to be using as the prefixes that Hurricane Electric gives me for /64 and /48, are different from the tunnel's endpoint address. At least I think I'm reading it right from the tunnel's information page. So when I use those to configure dhcpd6.conf and try to run (the second) dhcpd, it tells me it hasn't been configure to use any interface. Even though I'm telling it to on the command line I'm using to test the configuration. Regardless of what interface I tell it to use, it fails. So I was hoping someone has a working config that works with HE's setup.
