I'm trying to setup 15 or so different IP addresses that I'd like the eth0 interface to bind on. I've looked online at quite a few guides that show how to add multiple IP addresses to the /etc/network/interfaces file. However, they do not show a configuration in which different ranges of IP addresses are added on one interface.
I'm running Ubuntu 12.04 Server on VirtualBox. I'm trying to setup two interfaces with static IP addresses. If I only attach one network interface then eth0 works fine, but once I attach my second interface, eth0 doesn't work but eth1 does. I'm doing this because eth0 is my management subnet and eth1 is my admin/employee subnet. Below is how I've configured the /etc/network/interfaces file.
