Hi Maurizio,

You are correct, you do have a Phase 2 mismatch.  The Shrew client is
attempting to tunnel all traffic from the client PC to the gateway
(e.g. <0.0.0.0>-<0.0.0.0>) whereas the gateway is expecting only
traffic for the local subnet (e.g. <192.168.0.0>-<255.255.255.0>).

You can correct this in the Shrew config. If you're using Windows, in
the Site Configuration, on the Policy tab (far right tab) do the
following:

1. Uncheck "Obtain Topology Automatically or Tunnel All".
2. Click Add and use the following settings:

Type: Include
Address:  192.168.0.0
Netmask:  255.255.255.0

3. Click Ok then Save.

If you're using Linux and editing the configuration file manually, you
have to change a couple policy-list lines.

From:  
s:policy-list-auto:1
s:policy-list-include:0.0.0.0 / 0.0.0.0

To:
s:policy-list-auto:0
s:policy-list-include:192.168.0.0 / 255.255.255.0

That should hopefully do it.
