After upgrading my Seeed CM4 carrier platform to 24.10.0, the router funcitonality is broken. From the OpenWRT host I have complete connectivity to both the LAN and WAN side, but IPv6 packets from the WAN are not being forwarded to the LAN interface. IPv6 works sometimes.
This was a sysupgrade from 23.05.05. Going back to 23.05.05 everything works fine.
Has anyone else seen this issue, especially on a BCM2711 build?
Resolved...there were several issues but the cause relevant to others is that I was serving up an IPv6 link local address as DNS server via DHCP. The upgrade caused the link local address to change, so...it is always DNS.
Aside from the, the packet issues had to do with some configuration around a tunnel interface that I cleaned up, but that issue is unique to me.
