1.4  Applications for the Device 
Here are some example uses for which the Device is well suited.
1.4.1  Internet Access
Your Device provides shared Internet access by connecting the DSL port to the DSL or MODEM 
jack on a splitter or your telephone jack. You can have multiple WAN services over one ADSL or 
VDSL. The Device cannot work in ADSL and VDSL mode at the same time.
Note: The ADSL and VDSL lines share the same WAN (layer-2) interfaces that you 
configure in the Device. Refer to 
 for the Network Setting 
> Broadband screen.
Computers can connect to the Device’s LAN ports (or wirelessly).

Device’s Internet Access Application 
You can also configure IP filtering on the Device for secure Internet access. When the IP filter is on, 
all incoming traffic from the Internet to your network is blocked by default unless it is initiated from 
your network. This means that probes from the outside to your network are not allowed, but you 
can safely browse the Internet and download files.
