Firewall block in rule of Ethernet client

[marmot74]

Hi,

I am having an issue accessing the web UI.
Thinking I may have done a mistake in my config, I decided to investigate. After some research using the command line (= connecting my Opnsense box to a keyboard, mouse and hdmi screen) I see that a rule (block in on igb1) seems to be preventing my MacBook from getting a proper DHCP IP address. The MAC thus auto-assigns a false 169.xxx IP, which in turns puts me in a different network than the Opnsense box. Reason why I cannot connect to the UI.
I decided to put the Opnsense box back to the factory default setting (I have a copy of my settings in a safe place) to start fresh. I did this in the command line.

Now, I try to connect my MacBook via Ethernet to my Opnsense box (LAN port) and still get the same firewall block when the MacBook is asking for a DHCP address. I am stuck and this is surprising since I had been connecting my box with Ethernet until now and it worked perfectly

Any ideas on how I can solve this ? I have been searching since yesterday early evening. I don’t understand why this fw rule is blocking me, I never saw it as a default rule before !

Thanks for you help
