Has 'gateway [1]' above got IP forwarding enabled ?
(sysctl -w net.inet.ip.forwarding=1)

'gateway [2]' above needs to know about 192.168.1.0/24, otherwise
it'll send packets to 192.168.1.2 through its default gateway, and
never reach their intended destination.  So, it needs a static
route added for 192.168.1.0/24 through gateway 192.168.0.2
