Title says it all.
If yes, do you experience a failure of all IPv6 connectivity from WAN to LAN after 3 to 4 to 5 days of continuous operation?
I do on firmware 1.0.2.7, I have no special firewall rules set, and I can't figure out why this always occurs.
The "fix" I've discovered is to go into Networking > IPv6 > change and save something under IPv6 WAN Configuration. This sometimes but not always gets Lan to Wan IPv6 connectivity working again. When this fix doesn't work a reboot is needed. I know the WAN IPv6 is always working because the diagnostics are able to ping, trace and look up IPv6 only URLs.
