Some information about my setup:
-i have 4 physical interfaces
-my wan interface is a pppoe connection running over a tagged vlan on one of my physical interfaces
--i have a public ipv4 adress and another ipv4/29 subnet
--i also have a /48 public ipv6 prefix, delivered via dhcp6-pd
my internal interfaces are a mix of vlans and physical interfaces, some bridged some not All of them are:
-configured with an ipv4 adress in private space via Interfaces->Name static ipv4
-configured with an IPv6 ULA adress via same interface
-configured with an IPv6 publicly routable adress via virtual IP configuration.
On interfaces which need autoconfiguration DHCPv4 is set up as well as RA
RA advertises 2 routes, both with a prefix length of 64:
-the publicly routable adress
-the ULA
RA is configured to do assisted RA, the intention is to allow SLAAC for public adressing, while registering ULA in the DHCPv6 server.
However no matter what I enter I cannot get DHCPv6 configured with a range, all adresses I enter are rejected saying they are out of range: see attached picture.
Am I misconfiguring or running into a bug?
-
Odd. I've just entered that range into my test unit, after setting 1 as the LAN address and it works.

I believe it is due to the virtual IP, and perhaps some of the RA bits. After commenting out the blocking bits and looking at what is written to the config I saw that it was configuring for the public v6 range and not the ULA range, while displaying the ULA range in the interface...
I've filed an issue on github.
