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



  • 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.
