Hi,
I'm using DIR-825 Rev. B2 (according to the sticker at the bottom side of the device; the Web-GUI says it were Rev. B1) with the latest EU firmware V.2.09EUb09 (date 14.01.2013) -- details about this firmware and where to get it, see here:
New EU firmware version 2.09EUb09.
I tested both
6to4 and
IPv6 in IPv4 tunnel (copied your configuration data), but I couldn't reproduce your negative results concerning the status pages. There is one exception: It is not always possible to show the current
LOGS pages, but this phenomenon is independent of IPv6 configuration and happens from time to time (in all firmware versions I have used so far: V.2.04EUb02, V.2.05EUb09 and 2.09EUb09). It disappears after the next sending of a full log via e-mail.
The only strange thing I saw from your config_with_ipv6.bin file is your local IPv4 address: 192.168.0.1/255.255.254.0 (this corresponds to the range 192.168.0.0 - 192.168.1.255). This might be okay in terms of CIDR, but I don't know what your DIR-825 box "thinks" about that.
