Chapter 1 Getting to Know Your ZyXEL Device

Figure 1 Router Mode: Internet Access via a Broadband Connection

You can also configure firewall and content filtering on the ZyXEL Device for secure Internet
access. When the firewall is on, all incoming traffic from the Internet to your network is
blocked 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 for
example.

Use content filtering to block access to web sites containing keywords that you specify. You
can define time periods and days during which content filtering is enabled and include or
exclude particular computers on your network from content filtering. For example, you could
block access to certain web sites for the kids.

Use bandwidth management to efficiently manage traffic on your network by giving priority
to certain types of traffic and/or to particular computers. For example, you could make sure
that voice over Internet calls get enough bandwidth in your network, and/or limit bandwidth
devoted to the boss’s excessive file downloading.

1.2.1.2 Internet Access via a Dial-up Connection

Alternatively, the computers connected to the ZyXEL Device can share Internet access via the
built-in 56K modem. If both the broadband and dial-up WAN connections are set up, the
ZyXEL Device uses the dial-up connection (via the modem) as a backup. When the primary
broadband WAN connection is down, the ZyXEL Device changes to use the dial-up WAN
connection automatically.
