Zyxel SSL 10 private DNS ISSUE

Hi all.
I put in place the Zyxel SSL 10 just received. After some teaking with the
initial setting (too long in my opnion) I was able to run the
appliance.
When I connect from outside the SSL vpn is establish and work. I can ping
any inside machine but the only issue is that at the VPN client is not
assigned the DNS (internal DNS) even if I set the DNS IP to assign in
Remote IP configuration.
In this way the machine is pretty unuseful since Is quite impossibile to
ask users to work via IP insted of names.
This is my largest issue. It appears to me a bug. Also I have upgraded to
the latest firmware avaiable on Zyxel Wbe site 1.00(AQH.2).


Anyone having my some issue?

P.S.
The machine also do not handle well the reverse proxy with Outlook Web
Access.
