Didn't see his post before I completed mine. Sorry for the duplication.

The default-network command is classful. The route 3.3.3.0/24 is not
classful. Because of this, it becomes a pain in the butt essentially :
) What you will need to do is ip default-network 3.3.3.0 -- this will
add a static route into your routing table to 3.0.0.0/8. THEN you can
issue "ip default-network 3.0.0.0" and it should show up as a cadidate
default as well as the gateway of last resort.

HTH.
