Well, in this case, the "router to the outside net" is an Ascend ISDN router,
so it is needed to connect to the outside (I don't have a way to make the NAT
box -- a NetBSD machine -- speak ISDN). I was hoping that rather than setting
up two ether segments (one shared between the NAT box and the Ascend and one
shared between the NAT box and the inside machine(s)) I could put all the
machines on one segment (it saves a hub and a NIC).

you can use the NAT box as the router.. with PPP link to the Net and
ether to the LAN.
