Hello,
i am using the setting you can see in the screenshot.

As you can see the the dhcp-client has the status bound however it does not have any prefixes. I sniffed the packets and I can clearly see that the ISP’s DHCPD is sending out prefix delegations but for some reason the router chooses to ignore them. The captured traffic can be downloaded from here: https://drive.google.com/file/d/0ByyF9pn_vWmkUHpjQmxKZ3FycHc/view?usp=sharing
Update
I activated the debug logs and in there it actually says that the dhcp client is “not interested” in the delegated prefix. The question is why.
