A forewarn, I'm a newbie, so ignore my posting if you want.

139.x.x.x, if I'm not wrong, IP starting with 139 is only served by Telstra
dial-up bigpond. Coz usually, what I think is, Australia is kinda assigned
by, who I don't really know, IP addresses that starts with 203, except for
education institutions, esp. universities, which have different from the ISP
starting IP. Observed this kind of occurance even in Singapore.
and eth0 is connected to... ?? cable modem? some kind of internet connection
such as ISDN, xDSL, Office LAN (not home LAN)??
Machine #1 will be reachable through the IP that's assigned to PPP, assuming
of course eth0 is connected simply to your LAN.
Can't figure that out. 
Anyway, if I'm not wrong, ip for a gateway doesn't need to end to be
x.x.x.0, (right?), so you can simply eliminate adding that entry, it's
simply for easier bookkeeping.

As everybody has knew that most of the TCP/IP in Windows NT are borrowed
from UNIX. So, whatever command you use in UNIX is applicable to Windows NT
too... to add routes, simpley "route add"
explicitly:

> route ADD 157.0.0.0 MASK 255.0.0.0  157.55.80.1 METRIC 3 IF 2
         destination^      ^mask      ^gateway     metric^    ^
                                                     Interface^

|  Machine 3 and more on the same hub but with private addresses
|  	eth0:	192.168.0.1 	netmask 255.255.255.0
|  route add net 203.x.x.0 eht0
|  default route GW = 139.x.x.x eth0

I might be wrong... so flame me, still learning every second here.
