Locked out! - deactivated all LAN ports, only WAN open

[Totalnoob]

Hi all, new to OPNSENSE.

I had a working fine setup with a DEC2750 when I accidentally turned off the LAN interface (the only one) trying to switch it to another physical port on the firewall. It logged me out as I was connected via that interface.

Now I only have WAN interface as assigned port and have no way of logging into OPNsense. I tried serial via the guide however, command can’t find the directory to screen it. I’m not sure if it was even set up.

How can I log back in to assign a interface or even factory reset (doesn’t seem to be a button on the firewall).

TIA

I was able to log in to serial with PUTTY but shows no options. If I type “sudo ifconfig igb0 up” it doesn’t change, i still can’t access web gui.

Any assistance to enable LAN interface or reset to factory greatly appreciated.

if the box has got an active network connection, i.e. you can ping systems via WAN, you can disable the firewall and should be able to access the UI via WAN:

pfctl -d

HTH, be careful,

Can you access the opn shell via the root or an account with wheel/sudo rights?

/usr/local/sbin/opnsense-shell

From there you can reenable the interfaces, load a backup config, or factory reset.
