Do I really need to setup static routes, if all 3 devices are on the
same subnet? Here's the current config:
Device IP Mask GW
eth0 192.168.2.235 255.255.255.0 192.168.2.1
eth0:1 192.168.2.236 255.255.255.0 192.168.2.1
eth0:2 192.168.2.237 255.255.255.0 192.168.2.1

The reason I'm doing this is that each device is being used by a
different Instance of an emulated Mainframe running Different OS's (VM,
VSE, and ZOS). Each Operating System is running tn3270, ftp, and
several other services, and each can talk to the the host linux and the
world but not each other.
