Look at the ifcfg-* files under /etc/sysconfig/network. There should be one 
for each of your interfaces. Add a persistent name to each of them like so:

PERSISTENT_NAME='external'

Call them whatever you want. Good choices are 'external', 'internal', etc.

Now instead of eth0 and eth1 you have more logical names that will always 
refer to the same interfaces no matter which order they came up in.

Hope that helps,
