Hi, now i have another big problem; After a period where everything seemed to be working now this happens: the firewall works regularly for a while then the lights of the network cards go out and the only system is to unplug and restart the firewall because it does not connect to the web interface and not even ping.

    @LeviPonti CPU usage 50% is not quite high. When the lights of the network cards go out, is there anything wrong with the traffic go through the firewall? Is the whole device frozen? Try to connect serial console and see any abnormal messages appear on console.

    a few moments ago the problem recurred and by diverting some subnets to another outlet the lights of the network cards came back on and the firewall started working again.
