Are you trying to access the Qube internally by name or ip address?

If by name, what happens when you use its local ip address?

If by ip address works, what are you using for your DNS server?

Do you have a local (internal) DNS server?

One possibility is that you are resolving the "external" address of your
Qube and the traffic is being routed to the internet and not to the Qube.

What I do is set the Qube up as a DNS for my domain with local (internal)
addresses.  Then set all local machines to use the Qube for DNS.  This way
local hosts in your domain will resolve locally.  I then use external hosts
for Primary and Secondary DNS for my domain (i.e for the reast of the
world).  When the Qube can't resolve a name it will forward the lookup to an
external DNS and pass the result back to the local machine making the
request.

Now local machines will get the Qubes local address and not the external
address and all should be well.

I hope this makes sense and helps.
