one thing coming to my mind - is that some Linux Distributions - like e.g. Ubuntu - link the interface number (ethx) to the Mac address hard via the udev daemon. This means - if you copy the configuration (network) onto another Hardware-System - you will not get eth0,eth1 ...ethn, but everything will start at: eth0+n,eth1+n ... ethn+m. Mean - you will eventually only get the default networkinterface configured as fallback. Under Ubuntu - check the /etc/udev/rules.d/70-persistent-net.rules file and adapt the mac-address accordingly. Dunno if Debian itself is handling the same way. Long time I've not used debian (since they suddenly dropped support for debian 3 - without pre-notice - I switched over to Ubuntu LTS Server).
