DigiOne Port Security Setting

I am trying to select the option “Only allow network access from the following devices or networks” from the list. However, when I apply the change, it reverts back to the original setting of “Do not allow network access to the serial device”. How do I get this to save? Is there a setting I’m missing that disallows this change?

I believe that’s a known bug, and will be fixed in the next version of firmware. For the time being you’ll need to make those changes via commandline, using the “set auth” command. Here is a link to the current command reference for more info on that command and it’s syntax. Examples are included in the manual:
