OK, I submitted the following:Short version: Flow tracking during heavy SMB traffic looses the netfilter midstream connection tracking, rebuilds a temporary ESTABLISHED connection, and a downstream ASUS/Broadcom component mishandles the rebuilt conne...

Great, thanks for the heads up about the new FW version. I applied it, played a movie on my Shield, and it stopped 3 mins in. So no fix for the spoofing issue.Good news, the Kodi fix I made is working great. I'm a little nervous running a router that...

I've created two workarounds to the "mishandling Netfilter connection-tracking TCP loose mode" bug.First, I'm a Kodi developer, so I simply patched Kodi to handle TCP resets at the samba dependency layer: https://github.com/xbmc/xbmc/pull/28829. Kodi...

The failure path appears to be this:The Shield requests SMB data over Wi-Fi.The router receives that traffic on `wl1.1` and forwards it through `br0` to the wired SMB server.The SMB server replies normally.At some point, the router loses the original...

So this does appear to be a firmware defect. The evidence points to the firmware losing the SMB flow’s tracking state, then mishandling the reconstructed connection and generating a reset.This is a normal LAN-to-Wi-Fi connection through br0 and wl1.1...
