Or an alternate Net config to achieve the following ...

i have three network segments N1, N2, N3 and PC with one NIC
the machine is isolated by switch for N1.

PC{N1,N2,N3}<-> router <-> switch {N1} <-> main network {N1}

N1 main network uses/requires DHCP for main net access

N2,N3 are for local TCP devices, software testing through PC local router
and are not to be visible to N1 on other side of switch.

so what i want is to multi-home PC on N1,N2,N3 where N1 address is assigned
via DHCP and N2,N3 are manually configured to desired host address

I can get it to work manually by adding Host addresses to TCP/IP properties
but the auto DHCP part is causing my worries

TIA

You cannot do that. You can "multi-home", by which you mean put multiple
IPs from different networks on the same NIC, but they have to be fixed IPs,
not dynamic.
