I found out that dhcpd is bugged in fw from older models,  dir 600 or 625, so I think that they are aware about this problem. They just don't care much about it, since is not so important, no many users have or care about ipv6 now.

How did you find this out? Those older models are different in code and HW and not the same as the 868L even thought spec should be the same for IPv6. Besides the 600 and 625 are no longer made here thus not developed on anymore.

I recommend that you do phone this in and ask about it.

Some users had the same problems with older models. I'm not a specialist in ipv6 or networking so it's not so easy for me to describe exactly the problem by phone, and usually on the phone you get some p.r. employee who is even more "noobish" than you... If after the next two fw version this issue is not addressed,  I'll try to contact them  by email with some logs and screen shots.
So far is not that irritating,  I don't restart the device often, until now I did it for testing purposes only.

OK, I recommend that you use phone to make contact. Prior experiences with email is less than a solution and usually will direct you to phone in anyways, if you get a response.  :-\

If I don't get a response they will find a surprisingly high number of bad reviews compared  to the number of units sold lol. I'm a patient client but if  I make the effort to send a decently documented support ticket I expect to be answered :D

Well, just letting you know that from my experiences and seeing others experiences here on the forums and on FB, email support is less than satisfying. Even though having to wait on the phone takes longer, it's well worth talking to someone ON the phone rather then waiting for email. Besides you'll probably get quicker response on the phone.

Good luck.

Fri Sep 6 08:28:03 2013    Exiting, sigterm or sigint received.

it is quite obvious, that for whatever reason the config files for both the radvd and dhcpv6 service are erroneous and hence unreadable which in turn produces syntax errors and parsing failures when the starting processes try to read them. As a consequence neither radvd nor the DHCPv6 server will start.

Given you use the Autoconfiguration Type "SLAAC+Stateless DHCP" when radvd is not running the router won't send any router advertisements into the LAN. That's why your LAN PCs won't learn any global IPv6 addresses from the /64 prefix your router has learned from your ISP by DHCP-PD. If in addition the DHCPv6 server is not running your LAN PCs won't learn any IPv6 DNS server addresses.

Given your router is still working in a correct manner concerning IPv6 routing you could circumvent the problem by configuring your LAN devices manually:

Look at the router's IPV6 CONNECTION INFORMATION to see what is your present IPv6 Network assigned by DHCP PD (for example according to one of your srceenshots: 2a02:2f0e:9031:4100::/64), what is the LAN IPv6 Link-Local Address (for example: fe80::7a54:2eff:fefb:394c) and what are the Primary and Secondary IPv6 DNS Servers (for example: 2a02:2f01:30:2:0:405:465:1 and 2a02:2f01:30:201:0:405:465:1).

Go to your first PC and form a suitable global address for it, for example taking the present value 2a02:2f0e:9031:4100::/64 for IPv6 Network assigned by DHCP PD you could choose the address 2a02:2f0e:9031:4100::1 with a prefix length of 64 to configure this PC manually. Configure the value fe80::7a54:2eff:fefb:394c (your router's LAN IPv6 Link-Local Address) as the default gateway for your PC. Finally configure both the values 2a02:2f01:30:2:0:405:465:1 and 2a02:2f01:30:201:0:405:465:1 as primary and secondary DNS server.

This should work but has the disadvantage that you have to reconfigure your PC's global IPv6 address when after a reconnect of your router to your ISP it gets a new prefix value for its IPv6 Network assigned by DHCP PD. To circumvent this you could ask your ISP for a fixed prefix that never changes...

Of course the real problem is a bug within your router, maybe the storage it uses to store its configuration files is defect. I would ask your vendor for a new device.

 Thanks for taking the time to explain the log and a possible solution.
I actually ended up using stateful dhcpv6, and ULA enabled. After router reboot i just enable/disable ula a few times and magic happens :)
 I still hope that this is a firmware related problem, i think that there are some more config files on the router and the errors are always the same.
