About Your Router
Congratulations on your purchase of the ZyWALL 10 Internet Security Gateway.
Don't forget to register your ZyWALL (fast, easy online registration at www.zyxel.com) for
free future product updates and information.
The ZyWALL 10 is a dual Ethernet Internet Security Gateway integrated with robust firewall solutions and
network management features that allows access to the Internet via Cable/ADSL modem or Internet router. It
is designed for:
Home offices and small businesses with Cable, xDSL and wireless modem via Ethernet port as Internet
access media.
Multiple office/department connections via access devices.
E-commerce/EDI applications.
Your ZyWALL 10 is easy to install and to configure.
The ZyWALL Web Configurator (Web Configurator) is a web-based utility that allows you to access the
ZyWALL's management settings and configure the firewall. All functions of the ZyWALL 10 are also
software configurable via the SMT (System Management Terminal) interface. The SMT is a menu-driven
interface that you can access from a terminal emulator through the console port or over a telnet connection.
Note: You can configure all features of the ZyWALL 10 via SMT but we recommend you
configure the firewall using the ZyWALL Web Configurator.
