You need to either:
a) configure the routing tables appropriately, so that any hosts which
are on the eth0 side of the Linux box know that they have to use it as
a gateway to the NT box, or
b) configure the Linux box to perform proxy-ARP for the NT box, i.e.
arp -i eth0 -Ds 129.240.186.y eth0 pub
In either case, the NT box will need to have the IP address of eth1 as
its default gateway.
