Can't connect to WAN router webadmin from LAN

Installing and Using OpenWrt
1

Hello,

I replaced my WAN router (Fritzbox with stock ROM) and now I can't access the WAN router web admin.

internet connection works ok.

My setup is WAN router (192.168.100.1) <-> LAN router (192.168.201.1).

I have not touched the config of the LAN router. So I think there might be something off on the WAN router. I have saved and restored the configuration, but I think this did not work for all settings.

Are two routers required in your network? Can you remove one of them?

Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:
