i am having some trouble with configuring OpenWRT (10.03.1-rc6) with IPv6 conectivity. I have set up the router to use IPv6, radvd, DHCP6 Client for dynamic prefix and DHCP6 Server in hopes it will work better (tried also without the server just radvd). My Windows 7 x64 machine gets the global IPv6 address fine, but the IPv6 default gateway and DNS remain emply (gateway has a local-link address). When i try to ping ipv6.google.com i get request time out. However if i ping my Global IPv6 br-lan address which works fine and then ping ipv6.google.com then everithing works fine, for a short while (arround a minute or so) and than its back to request time out.
Also i get a dynamic /64 prefix from ISP via DHCP6 and radvd only configures IPv6 Global addresses on one machine in my lan out of 3, all running Windows 7.
These are my config files:
