Summary - ipv6 broken on Xiaomi Redmi AC2100
Task Type - Bug Report
Category - Base system
Status - Unconfirmed
Assigned To - 
Operating System - All
Severity - hoch
Priority - gering
Reported Version - openwrt-21.02
Due in Version - Undecided
Due Date - Undecided
Details - Most of my clients can't connect with my dual stack internet connection with IPv6.

I tested now a lot, but cant get it working on my Xiaomi Redmi AC2100.

When I ping outside (eg. to google.com) with IPv6 I never get a answer back.

When I run tcpdump on the Gateway running OpenWRT 21.02 (tested now with rc4 to .1) I see the packets leaving the wan interface and I also see the answers on the wan interface.

But the answers don't come back to the lan interface.

I tested to enable/disable source based policy routing
I tested to enable/disable network.globals.packet_steering

I also have flow offloading switched off!

First I was thinking, is works with windows, but this seams just we random - what is working and what not... now it is also not working on my windows - where it was working before (the screenshots come from that installation)

The problem is also reported to the forum at https://forum.openwrt.org/t/ipv6-issue-with-dsa/107138
