problem using static ipv6 config

[SjoerdNLD]

On my ac66u I can ping ipv6.google.com no problem:

PING ipv6.google.com (2a00:1450:4001:c02::66): 56 data bytes

But on any pc in my network it fails:

Tracert shows it finds my ac66u: (pic attached)

Can somebody point me in a direction?

Are you sure your LAN prefix is correct? Typically a prefix delegation will be a different network than the network of your WAN address. Also, you may try using the gateway's link-local address, this is what the router does with Native/DHCPv6 connections. I'm not sure if this will make a difference, but may be worth a try.

For example, Comcast assigns host address on the network 2001:558:[something]. Prefix delegations are from the network 2601:[something].

Sjoerd, if you have this working could you please tell how you did it? Tried this also several times with no luck. Also with the link-local address as stated as above. I think you're provider is also xs4all as can see from the DNS settings and then you may probably also be using a Fritzbox modem.

Correct, i had it working on 35.4 with a fritz 7170 and pppoe with static v6.
But after upgrading to 37 it stopped, I tried going back, but it doesn't works.
I'm now using the 7360, it does not support pppoe as far as I understand.
What do you have?

Prefix is /48 actually, but thats assigned on my modem.
Situation is as follows:
WAN -> Modem -> ac66u
Where Wan is 2001:980:32c5::/48
modem issues 2001:980:32c5:1::/64 if i connect direct

The problem is that the ac66u is not passing v6 packets to the modem (eth0) from the lan (br0).

I'm also using the 7360. I only could get it to work to set the DHCPv6 of the modem to assign DNS server, prefix (IA_PD), and IPv6 address (IA_NA). If the router then was set to use native IPv6 with DHCP-PD it started to work when the router was restarted on the .939 Asus firmwares and below. I also copied the values from the IPv6 log tab when it was working and tried experimenting with that values to make it static. I'm wondering if something have to be set in the modem to allow a router to create its own subnet.

Does anybody know what need to be done to get the router to pass the ipv6 packets?

A hint where to start reading maybe?

I wen't back to different versions, but could not get it to work properly.
I set the ac66u to AP mode for now, and using the fritz as router.
Solves the ipv6 problem, lost my dns config as the fritz doesn't have the options for that.

Same here, tried several configurations yesterday with the Asus .4422 release, static and with dhcp v6, couldn't get it to work also. Seems like the latest releases aren't compatible with the Fritzbox anymore. I've given up on ipv6 for now. Now running merlin .39 with ipv4 only.

Small update: I build freetz and load it in the fritz, works brilliant, DNS config solved and all works as normal again. I took the "trunk" version using the vmware player. It makes the last version available 06.04. Still using the ac66u as ap with the radio disabled on the fritz.
See here for more info:freetz and nl

This should (hopefully) be fixed in Asus' 4561 firmware, which will be included in Merlin .40 once it is released.

Already tested the. 4561 version of Asus. The ipv6 issues in router mode in combination with the Fritzbox are still there. Can't get it running anymore.
