I have a large enterprise network where I want to prevent NAT by any user / department behind departmental firewall or his layer 2 managed switch. Can it be done and can NAT be prevented altogether in a network?

    According to your Q, it seems that, wanted to block a pc/ user behind nat ! As it is assuming, for this purpose, if can provide a spare pc, can download "m0n0wall"(simple & free tool) for securing nat. Though not sure, but you may try here: http://m0n0.ch/wall/downloads.php

    How do you mean this? You "prevent" NAT at the firewall by not using NAT. But why would you want to?
