NAT *does* break things. You can't easily do IPSec through a NAT (meaning you need to do some tap-dancing if you want to VPN from one). NAT breaks a lot of end-to-end stuff - for instance, if you have a NAT, it's *REALLY* hard to have 2 different machines running servers on the same port. http://www.ietf.org/rfc/rfc3027.txt?number=3027 for all the gory details
