GUI Layout & Main Components

[lilsense]

are you really asking for help? or hoping someone to assist you on other related issues??? LOL

post as many screenshots as you can from the GUI and hopefully anyone here can tell you why you are plugged in to the WAN port as opposed to LAN, would be my wild guess. LOL

Use newly installed OPNsense appliance. Plug PC or Mac into LAN port. Enter 192.168.1.1 into your browser's address bar.

That's how you access the UI.

If you do a basic install it will show the WAN *AND* LAN IP.
I see no WAN IP in your picture. Did you connect it to your ISP?

That said, even without internet you should be able to access the routers GUI. But i miss the LAN interface in the picture. Did you manually changed stuff?
