setup NAT with one ethernet port?

is it possible?
the example is like I have a 5 port switch and one adsl modem with dmz setup to MT box, my pc is also connected to same switch and I am setting MT as my default gateway, and mt will do NAT over same Ethernet port but two different ip subnet such as:

10.1.1.1 (Adsl-modem set DMZ to “10.1.1.2”)
10.1.1.2 (MT BOX)
192.168.1.1(MT Box)
192.168.1.2(MY COMPUTER)

Thanks

possible ? not possible ? any idea?

This should work, MT doesn’t care I don’t believe. With Cisco you have to dink around with Nat on a Stick configs, but I believe MT would just treat it like anything else. Just setup a src-nat and dst-nat with the IP addresses and see what happens.
