@hui.wang: Only the RPi is acting as the IPv6 gateway for the network (it sends router advertisements to internal LAN on br0, issued by dnsmasq - the relevant dnsmasq config is here: https://github.com/myxal/DigitalHome/blob/master/configurations/dnsmasq/dnsmasq.d/Echolife6.conf
The mac is unaware of the tunnel, it autoconfigures itself according to the router advertisements, and RPi forwards the packets according to normal forwaring rules. But we're getting off-topic here. Regarding your config - the internal (br0) and external (he-ipv6) should have addresses from different prefixes. I'm not sure which of the settings is wrong, but seeing as you are setting the gateway to what looks like a correct address, I'm guessing your internal address is wrong. On tunnelbroker, this is listed as: "Client IPv6 address" - this is the external address, and must be set exactly as indicated by tunnelbroker "Server IPv6 address" - this is the gateway - seems correctly entered in the config "Routed /64" - this is the prefix from which you'll pick an address for the internal (br0) interface. I picked ...::1 because it's easy to enter and remember. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1861936 Title: Raspberry Pi 3 network dies shortly after a burst of SD card IO and network load ((lan78xx): transmit queue 0 timed out) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi2/+bug/1861936/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
