Can't connect to the Pfsense Web GUI when Wan is plugged in

[wizencrowd]

Hello

For a school project I need to configure a server with pfsense. We want to use it as a captive portal. My problem is that I can't get in the WebGUI when I have my Wan connection plugged in. When I freshly booted my server I need to unplug the wan cable, then I can login in pfsense. After that I can plug the wan cable back in an everything works. Do you guys now How i can fix this? When I booted the server I don't have internet, but when I login in pfsense I get internet.

Some info that might be usefull:

• Lan IP : 192.168.1.100

• Wan IP : 192.168.1.103 (DHCP)

Hope you guys can help!
Thank you!

Thanks for the info.
You totally broke one of the most important rules when it comes routing.
KEEP LAN on 192.168.1.1/24
Make WAN something 192.168.2.1/24 or 10.0.0.1/16 but NOT in the 192.168.1.1.1/24 segment.
IF your WAN needs to be in 192.168.1.0/24 then make your LAN (example) 192.168.2.1/24

Remember : your are operating a router/firewall, not a switch.
