Is there some software out there that will load balance 2 nics? I want to get another DSL line into my office and load balance them so I can use the full bandwith of both DSL connections from a single program.
Unfortunately it's not that simple. At minimum you will need a dual WAN broadband router (I say minimum because they are the easiest to set up), from there you could do it with various other solutions from Cisco, etc. I have never tried this with any form of BSD, but this might be possible as well.
