Gotta agree with Tim here. I don't see the point for having two nets on one interface. They'll be hard to keep secure with firewall rules if you run the same services on them. > I'll help, when I can. but forcing this on /etc/hosts is a dead end. Problem is that nfs and DNS don't work well at all. For nfs best use IP or /etc/hosts. One drawback of using DNS with nfs is that if the hostname cannot be resolved (network down, typo), one can also not get a console when it goes to single user mode [1] and has to reboot via power button. /etc/fstab is supposed to be static to begin with. It's supposed to provide the mountpoints the system can count on, so using IP's for nfs is preferred. For the more dynamic nfs mounts, one can use hostnames and use noauto in the options column.
