I don't think you need to add the 203.x.x.0 route, it gets made automatically
when you configure eth0 with its ip address (with kernel 2.2.x)

For this machine GW would be the ip address of Machine 1's
eth0 interface, 203.x.x.1

This isn't going to work. 

I think it would be neater if you gave Machine 1's eth0 interface 
two ip addresses, the valid 203.x.x.1 address and a private 192.168.0.1, 
then setup masquerading on machine 1, etc. Lots of fun.

Machine 3 would look like
  eth0: 192.168.0.2 netmask 255.255.255.0
	default route GW = 192.168.0.1 eth0
