Okay, I plugged it back in and tried pinging that IP from one on that subnet. Got nothing. I assume whatever came on the CD is Windows only stuff. I don't run Windows anywhere so I would have to setup a VM and make routing to it from the security network work. Would be a bit complex.
$ ping 192.0.0.64 -c 5
