Hello Ingvar, I think perhaps it will depend heavily on the capabilities of the NAS itself to do such a thing. If you are talking Cisco here, the NAS has all the same capabilities as a standard router. At least I can recall a setup we did once in the past where we allowed DHCP broadcast queries to "leak" from one LAN across a serial link and on the other side, to the DHCP server. There was a command named 'ip helper address' I think, don't recall very well, though. Perhaps this is a starting point for your quest :) Now, if you are talking about other NAS brands here, I won't be able to help.
