Usually when you forward X over ssh, DISPLAY is a port on the ssh client,
which is then forwarded by ssh to the remote port, that is, the port on the
remote server that the X server is listening on. So putty should be
automatically setting DISPLAY to something like  192.168.56.25:10.0 (ie
port 6010 on the guest) when you enable X forwarding. If it's not i'd say
there's something wrong with the putty setup.

That said, i think you should be able to just connect directly to
192.168.56.1:0.0 anyway - does Xming have an xhost setting? Does netstat on
the host show its listening on port 6000? Windows firewall?
