Chapter 1 Getting to Know Your ZyWALL
Traffic Redirect
Traffic Redirect forwards WAN traffic to a backup gateway on the LAN when the ZyWALL
cannot connect to the Internet, thus acting as an auxiliary backup when your regular WAN
connection fails.

Port Forwarding
Use this feature to forward incoming service requests to a server on your local network. You
may enter a single port number or a range of port numbers to be forwarded, and the local IP
address of the desired server.

DHCP (Dynamic Host Configuration Protocol)
DHCP (Dynamic Host Configuration Protocol) allows the individual client computers to
obtain the TCP/IP configuration at start-up from a centralized DHCP server. The ZyWALL has
built-in DHCP server capability, enabled by default, which means it can assign IP addresses,
an IP default gateway and DNS servers to all systems that support the DHCP client. The
ZyWALL can also act as a surrogate DHCP server (DHCP Relay) where it relays IP address
assignment from the actual real DHCP server to the clients.

Full Network Management
The embedded web configurator is an all-platform web-based utility that allows you to easily
access the ZyWALL’s management settings and configure the firewall. 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.
