What is the netmask of the Windows box's internal interface (the one
that is configured with the address 192.168.0.1)?  Make sure that it
is the same as the netmask that you use on the FreeBSD box's interface.

Just out of curiosity, why are you using a netmask of 255.255.255.255 ?
The RFC 1918 private class C network address 192.168.0.0 has a netmask
of 255.255.255.0 (by virtue of being a class C net).  On a truly private
network (i.e. not connected to the Internet), it doesn't matter what
network address you use, but if you are going to be connected to the net
and you use the RFC 1918 private network addresses, you should use the
proper netmask.  If for some reason you need more IP addresses, use
the 10.0.0.0 network (private class A, nentmask 255.0.0.0).  This will
give you 16 million host addresses.

What is the tu0 device?  I can't find any documentation on this driver
so I am assuming that you mean the tun0 device.  This is not needed on
the FreeBSD box in the configuration that you have described.

You will however have to set your default route to be the address of
the Windows box.  To do this, you will need to look up the man page on
route(8).  The command you use should look something like:

# route add -net default 192.168.0.1
