Adding the 192.168.0.x ip address(es) for your eth0 and/or eth1 
interfaces to the Debugger > External/Remote > Allowed Hosts list 
_might_ fix this.  From the log it appears that the debug process did 
manage to connect to the IDE but the IDE decided it was a connection 
from a remote host that isn't in this list.  My guess it that the peer 
ip address appears to be 192.168.0.x in this case and not, 
which is what Wing expects by default.

Note that the IDE listens on the configured TCP/IP port (default 50005) 
and the debug process connects to that port (and not the other way 
around, as might be assumed).

Please let me know if this does not help.
