Hi, I have been using CeroWRT on Comcast with a 3800 for about 6 month. The DHCP-PD config has always been a little unstable for me, but working. I recently upgraded to: root@cerowrt:/etc/config# uname -a Linux cerowrt 3.10.24 #1 Tue Dec 24 10:50:15 PST 2013 mips GNU/Linux My WAN gets a /128, but i cannot get DHCP-PD to work to get addresses on the rest of my interfaces. The router does seem to have good IPv6 access. I fiddled with the 6relayd config and came up with this, but it does not work. Any pointers on how to get this back on track? The result of the below config is that the /128 from the WAN interfaces is now present on all the interfaces but my attached computers get no addresses. config server 'default' option rd 'server' option dhcpv6 'server' option management_level '1' list network 'ge01' list network 'gw00' list network 'gw01' list network 'gw10' list network 'gw11' list network 'se00' list network 'sw00' list network 'sw10' option fallback_relay 'rd dhcpv6 ndp' option master 'ge00' root@cerowrt:/etc/config# uname -a
