Hi again,
Let's check the basics, just in case:
a) The ttylinux machine you are using is the one downloaded from our site,
so it is correctly contextualized.
b) And you are trying to access the VM 192.168.0.6 from a machine in the
same 192.168.0.X network, right?
You may want to try adding another NIC attribute to the template, attached
to your public network. This way you could access the VM from anywhere, not
just the private network.
