Couldn't access management | root cause

[Miata]

Hi guys,

Recently the management was inaccessible but it could be pinged. After a reboot the device was accessible again and all was well.

Is there anything I could run/see that could help me identify what happened around the time of the incident?

Regards

Depending on Firmware version:

from cli

diag debug crashlog read

might help you pinpoint something.

Are you not able to manage the firewall by the GUI? Have you tried to use Fortiexplorer, or just trying to SSH into a putty session with it? If you can SSH to it, run a sniff to make sure your management traffic is getting to the firewall. Run a flow to determine what is blocking the traffic.

Let us know how it works out.

The cli diag debug flow command is  your 1st step. Since ping works I would check allowaccess on the interface(s) and run a diag debug flow and with a sniffer on the interface(s) in question

e.g ( ssh and https on wellknown ports  for wan1 interface and local address 1.1.1.1 )

diag sniffer packet  wan1 "host 1.1.1.1 and  port 22 or 443"
