1.1.1 Internet Access
Your Zyxel 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
Zyxel 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 Zyxel Device. Refer to Section 6.2 on page 123 for the Network Setting > Broadband
screen.
Computers can connect to the Zyxel Device’s LAN ports (or wirelessly).

Figure 1 Zyxel Device’s Internet Access Application
You can also configure IP filtering on the Zyxel 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.
Only use firmware for your Zyxel Device’s specific model. Refer to the
label on the bottom of your Zyxel Device.
1.1.2 G.fast
You can have gigabit Internet access by connecting the DSL port to the DSL or MODEM jack on a splitter
or your telephone jack for G.fast.
G.FAST is the acronym for Fast Access to Subscriber Terminals, and the letter G stands for the ITU-T G
series of recommendations. G.fast is a technology providing gigabit speeds over traditional copper
twisted-pair wires. G.fast applies Fiber-To-The-distribution point (FTTdp) structure, which reuses the
deployed copper wire for the final meters.
