[photorat]

Hello,
I apologies if this question was already answered, I wasn't able to find it.

My problem after an wrong setting change I have only access to my opnsense using the serial connection, I need to set the listening port of the web server for the gui to the old value. where can I do this using the shell?

Thank you for your support!

Isn't there an option in console menu to revert to previous configurations? Just revert to the one before you made the wrong setting.
