Overload - ZyWALL USG 50
Hello. I have 2 ISP connections in 192.168.1/24 subnet. Yesterday I faced up with internet trouble. It works unstable, 50-70% of packages were missed. The gateway automatically changed to 192.168.1.10 and I do not have access even to web access for manage settings or see log. After 5 min all works fine, like nothing happened. I was surprised! Successfully I logged in web console and saw temporary overload of CPU in graph.
How to investigate what's impact to this issue?

Hi @follet
Welcome to Zyel Community. ?
When the CPU goes high, you can check session monitor to see if there is abnormal traffic/large session in Device.
Also, maybe you can find something abnormal event/log in device “Monitor > log”.
Session Monitor at “Monitor > System Status”
Log at “System > Log”

Thank you for respond.
In "Session Monitor at “Monitor > System Status”" I see only 50 records, not high load system.
In the "Log at “System > Log”" screen I see only notice by firewall, i do not see any other records. But firewall activity is too high (maybe) one record per each seconds.
Now CPU is 5-10% load as normal status, but sometime once a week the overload status can be.
