You can use MS Loopback Adapter Driver on your NT boxes.

If you don't have MS Lookback Adapter Driver installed on
your NT boxes, enter Network Control Panel, click the
Adapter section, click to add a new adapter, select the
MS Loopback Adapter. Your NT cdrom is needed here.

Then add your VIP (Virtual IP) address on the MS Loopback
Adapter, do not enter a gateway address on the Loopback
Adapter. Since the netmask 255.255.255.255 is considered
invalid in M$ NT, you just accept the default netmask,
then enter MS-DOS prompt, remove the extra routing entry.

This will make the packets destined for this network will
go through the other network interface, not this MS Loopback
interface.

As I remember, setting its netmask to 255.0.0.0 also works.
