I was stumped by the same issue of only one wired interface active at a time. I needed eth0 to be on a public routed network and eth1 to be on a private network so I can run a transparent proxy between them.
Solution I used is to open the gnome settings in upper right of GUI, choose the wrench icon and you should see eth0, eth1, network proxy listed.
1) Now go to eth1 and instead of configuring the "wired connection" settings, click the Add Profile button
2) In that profile configure what you need under IPv4 (IP, netmask)
3) At the bottom of the profile IPv4 settings tick the checkbox to "Use this connection only for resources on its network"
4) Apply that new profile 1 to eth1 and the interface should come active.
I'm using a mix of dhcp/static, but dhcp/dhcp should work too if you click the checkbox in 3). Only one interface can have the default route.
