LAN unreachble from OPNSense firewall

[nicholaswkc]

Dear all,

I installed opnsense firewall quite sometimes ago n this recently happen to my opnsense box.
I unable to ping from LAN to opnsense or opnsense to LAN. I don't know why, i did not alter any firewall rules.
I cannot even browse the OPNSense GUI from LAN nor connect to internet.
Is this sign of hack because last week i did encounter this issue and i did reinstall everything but now i want to recover via cli.

How to recover it? Thanks in advance.

I would first check if your hardware is functioning correctly.
Try a different cable for example.
What kind of network chip is in the router and in the pc you are pining from?
