yup. so you are close. assign ip's as you have them, then just add
your default route, which is somewhere in the 192.168.1/24 block.
everything is already taken care of - connections to your 10.20.2/24
would go out that the interface, everything else is out
the interface.

if you are curious, netstat -rnfinet or route get x.x.x.x to see what
the routing table will do.
