Hi,
i use the Beta firmware because the new functions. Flint3 act as router (Ethernet1/WAN) behind fritzbox 7530 (DSL+ pppoe, 192.168.178.xx). First setup with Flint3 only IPv4 works fine then i switch on IPv6 (Network→IPv6).
And then after confirming, Internet Connection lost, no access to flint3 with his 192.168.178.xx address and no access with 192.168.8. I reset Flint3 with the reset button. Then everything is fine and i see in Internet topic IPv4 and IPv6.
Regards
Matthias
It’s like yours i enabled IPv6.
I checked the logs and it looka that after pressing the reset button IPv6 is enabled and not before?

It's a bit strange, I think the ipv6 has nothing to do with the reset button. May I know did you reset the router configuration with long press reset button?
I press the button 4 or 5 seconds.
Oh, 4-5 seconds is to reset the network configuration.
If the issue reproduces again, please keep the environment (do not reset) and contact us to check remotely via GoodCloud. We couldn't guess what was wrong depends on currently info.
