You can definitely do it; I'll start with that.  In terms of software,
you'll need the basic TCP/IP stack that's installed by default, a DHCP
server, and I think that's about it for a basic setup.  You'd need to
configure the DHCP server to hand out leases for the IP range you
want, and then configure routing between the two network interfaces.
I don't know the specifics of how to do that offhand at the moment,
but it shouldn't be terribly complicated.  And yes, you could either
have that always on or only when desired.
