Back Orifice is a Windows app. Is the target / router really running
Windows?

You haven't provided any details of how the scan was configured or any
log messages from nessusd.messages, but I'd guess Nessus failed to
detect the target as alive. Check how you've configured the scanners;
eg, port ranges, type of scan, etc. For example, if you know tcp port
31337 is open, make sure your port ranges include that.
