Reconfigure pfSense - Make changes, Run wizard or Reinstall?



  • Hi - I would like to reconfigure pfSense, including changing router (SG-3100) IP address, DHCP server settings, subnet, hostname, domain name…

    Can I:

    1. Just make these changes in GUI

    2. Re-run setup wizard

    3. Or is a reinstall required



  • You can make your changes in WebGUI, or you can go to console, run option 4 and reset to factory defaults if you want to totally redo it all.



  • Terrific - thanks for the reply.  I will try the GUI first.



  • Ok - so changing the IP in the GUI resulted in an error on a red screen:

    An HTTP_REFERER was detected other than what is defined in System -> Advanced (https://192.168.34.5/interfaces.php?if=lan). If not needed, this check can be disabled in System -> Advanced -> Admin."

    So, via your instructions in the console, I reset to factory defaults.  During the wizard setup, I changed the LAN IP to my desired IP.  Immediately, I  am sent again to the red screen with the same error?



  • Rebooting the SG-3100 via console fixed the issue after resetting.  The reboot did not fix the error initially, after I had changed the IP via GUI.
