Hi Alexander,

The first thing that I see is that the address assigned to your Shrew 
client adapter (tap0) is in the same network range (192.168.0.33/24) as 
the remote network (192.168.0.0/24).  This usually does not work.  Try 
using another subnet, for instance 192.168.2.0/24 for your VPN client IPs.
