ZyWALL 10~100 Series Internet Security Gateway
SNMP
SNMP (Simple Network Management Protocol) is a protocol used for exchanging management information
between network devices. SNMP is a member of the TCP/IP protocol suite. Your ZyWALL supports SNMP
agent functionality, which allows a manager station to manage and monitor the ZyWALL through the
network. The ZyWALL supports SNMP version one (SNMPv1).
Network Address Translation (NAT)
NAT (Network Address Translation - NAT, RFC 1631) allows the translation of multiple IP addresses used
within one network to different IP addresses known within another network.

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. This feature is
not available on all models.

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.
RoadRunner Support
In addition to standard cable modem services, the ZyWALL supports Time Warner's RoadRunner Service.
