Hello
I’m experiencing a similar issue.
There are no problems with packet forwarding,

After a reboot, pinging the management IP works normally, but as soon as I access the Web UI or SSH from there, the ping response suddenly stops,and I lose all management access.
I’m using firmware version 12.0.19.7.
Regards.
