If NetAV Check is Incomplete
Read the instructions on the NetAV Check screen
and configure the necessary settings.
To complete the NetAV check without modifying
the advanced settings such as the port forwarding
setting for the router, the router must be UPnP
(Universal Plug & Play) compatible and the
UPnP function of the router must be enabled.
Refer to the instructions supplied with your
router and confirm the settings.
If your router is not UPnP compatible, you prefer
not to use the UPnP function of the router, or if
you tried to use the UPnP function but the setup
was unsuccessful, port forwarding needs to be set
on the router.
The settings for port forwarding may vary
depending on the router in use. For details, refer
to the instructions supplied with your router.

Tips
• Port forwarding is a function that allows network
communications with your router to be forwarded
directly to your network device (such as a PC or a
PSP system). It may also be called "Port Mapping",
®
"Address Change" or other names. To connect to the
LocationFree Base Station from outside your home
using port forwarding, you must adjust the settings
for the router to allow the data connection received
by the router over the Internet to get through to the
Base Station port (initial setting: 5024 (LF-B20/LF-
B10), 5021 (LF-PK1/LF-X11)).
• It is necessary to set the Base Station's IP address to
activate the port forwarding setting on the router. For
details, refer to the instructions supplied with your
router and the Operating Instructions document
supplied with the Base Station.
• Some UPnP-compatible routers are only compatible
with specific messenger services and games. For
such a router, set port forwarding.
