I've been trying to get this to work myself. As far as I've been able to understand, Swisscom gives us a /60. This should provide 16 /64 but actually only the first one is valid... and the Swisscom router takes it. It probably prevents DHCPv6 from getting to your router because the only available prefix (the /64) is already assigned on the Swisscom router. As far as I've been able to figure out, our options currently are to turn the router into a transparent bridge/firewall or remove the Swisscom box out of the picture completely.
Hello all I have a Swisscom internet connect with Internet Box 2. Behind that, running my home is a Pfsense box. The IPv4 setup was working perfectly but I'm struggling to get the IPv6 to work. I turned on IPv6 on the swisscom box and that works, it also gives an address to my Pfsense box but that's as far as I get. I read on this site that Swisscom gives a /60 so I tried setting up DHCPv6 requesting a /60 segment but that didn't appear to work. I tried a /64 as well. It occurs to me that the /60 is probably given to the swisscom box and is not forwarded to my Pfsense router. As far as I can tell, all my Pfsense box gets is a single IP (subnet is /64). Has anyone set anything like this up? I'm not sure what settings I should be using. Thanks
