Using Router OS with one NIC

Hi All,

So here is my issue, i have installed router OS on a spare EEE PC and it has only one NIC.

the way i want to utilize it is a follows

(WAN)—>(DSL Router)—>(PC with Router OS)---->(Lan)

I want the pc to act as the default GW for all the LAN devices as well as NAT and proxy.

Is this possible, if not what other alternatives do i have.
Thanks.

U need managment switch to use it like that, and then set up some vlans to work.
