About Your ZyWALL
Congratulations on your purchase of the ZyWALL 50 Internet Security Gateway.
Don't forget to register your ZyWALL (fast, easy online registration at www.zyxel.com)
The ZyWALL 50 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.
The ZyWALL 50 features an ICSA certified firewall, IPSec VPN capability (allowing up to 50 simultaneous
secure connections), MultiNAT (for multiple IP address translation), web page content filtering and an
embedded web server for easy configuration. See the next chapter for more details on these and other
features.
The embedded web configurator is an all-platform web-based utility that allows you to easily access the
ZyWALLs' management settings and configure the firewall. There is an embedded web help (click the Help
button) for the configurator as well as more comprehensive HTML help on the accompanying CD.
Most functions of the ZyWALL 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.
You can configure most features of the ZyWALL 50 via SMT but we recommend you
configure the firewall using the ZyWALL Web Configurator.
About This User's Manual
This manual is designed to guide you through the SMT configuration of your ZyWALL 50 for its various
