Sound like you want the omelet without breaking the eggshells. I think you need to handle this with routing. So I suggest you sacrify some subnet you do not want to reach normally and send that network out via the other link. (Say: 207.68.128.0/18 ;-) And just for good measures. If it is the backup link. How will you do the failover? (Not that is has anything to do with Nagios.) It might be worthwhile digging into the source based routing option of your network equipment. Hugo. -- I hate duplicates.
