hi massimilano,

If the no ip routing command is used then i am afraid that the 3560 will become an L2 switch and no routing will be done.

Removing default gateway on 3500 will also cause some problems as we dont know exact topology and config.

If you just want to disable intervlan routing but want to reach internet then try using ACLS.
