Can I install Untangle on a single computer to use as Parental Control software?
No. You cannot install Untangle on a single computer to use as Parental Control software. Installing Untangle will wipe out your existing operating system and all files on your hard drive. It can only be used as a Gateway to implement Parental Control or Web Filtering on connected client computer(s). For a single PC, other Internet filter/Parental Control software can be used.
