DR>Probably your routing table.  Basically your Win machine doesn't
know what route to take to the 192.168.0.20 machine, so it uses its
first bound card which in this case is the dial-up adapter.  If you
type in something along the lines of "route add 192.168.0.30
192.168.0.20" (can't remember the exact syntax) it should now realise
that when it is asked to talk to 192.168.0.30 (by a ping for example) it
should connect over the 192.168.0.20 interface instead of the default
one.  Try doing a "route print" before and after doing this and you
should see a new entry showing the route you just defined.
 DR> before you do that try changing your default
gateway (in the TCP/IP part of the Control Panel) to 192.168.0.20. 
This will mean you will need to start your dial-up sessions yourself
from now on, but that's no big deal really.
DR>Also, check that your two machines are both on the same subnet -
normally 255.255.255.0.  This can be checked by typing winipcfg or
ipconfig.  It looks like they are if your Linux machine can
successfully ping the other one.

Hope this helps,
