I guess what I am worried about is how the heck will the Backup know what to do with the traffic because it has 9 connected that are the same IP.
What kind of systems are we dealing with? are the Unix?
i dont know if this is a good solution but just 'thinking out loud' but you could have cron jobs to bring up the nic card, do the backup, then bring down the nic again. do this on each PC at different times???
It seems odd that these IP's are not changeable.. it doesnt make sence at all.. i have never known of a PC/server or anything that is set like that??
