besides our main internet connection (via a cable modem), my wife has a relatively slow DSL line as a backup (the cable used to be very spotty, years ago). I would like to use this DSL line (accessible via a Fritz!Box router) as a “hot spare” or - if that is possible - to take some of the load.
Is this something that is doable in IPFire? I moved to IPFire from PFsense and one of the reasons was the extreme complexity (for a regular guy) of some of the settings. PFSense apparently permits this type of routing, but unfortunately, I never got it to run.
