Latest firmware 24.10.5
Two different routers 7490 Avm Fritzbox
This router has 4 ethernet ports (lan1 lan2 lan3 lan4) and another ethernet port which is seen as eth0 (I think is the port for ftth). Today I have tried to make some configurations (I need tree ports in bridge+1 separated for dmz), but i see something strange..
ifup lan3
Interface lan3 not found

Firmware error?
Using the standard config from firmware.

I will try tonight a snapshot and I see if lan3 and lan4 return to live.
