Different IP address

[Orazio]

Maybe bother with stupid question, but I would
appreciate some help.

I have a small LAN at home with router which is also
DHCP server.
When I start VNC in user mode it show me the correct
IP assigned by router: 192.168.0.2, but when I start
VNC in service mode (which is the one I need because
PC runs unattended) the IP shwn is 127.0.0.1
(localhost) and thus connection with client is
impossible.
Anyone could advice me how to deal with this?

Regards

Orazio
