Chapter 1 Introduction
Thank you for purchasing ZSR0104C SERIES Broadband Switch Router.
This chapter covers a brief description of ZSR0104C SERIES features, package content, installation
requirements, and the organization overview of this User’s Manual.
1.1
The ZSR0104C SERIES Broadband Switch Router
ZSR0104C SERIES Broadband Switch Router is the ideal router for sharing a single IP address
with multiple users, providing firewall security, and accessing WAN with high speed for Home and
SOHO (Small Office and Home Office) needs.
ZSR0104C SERIES Broadband Switch Router
offers its simple operation such as easy setup. It also provides networking professionals with
advanced features like DMZ and Virtual Server (Port Forwarding), Service Filtering, URL Filtering,
and Dynamic DNS etc. ZSR0104C SERIES will help you securely connect multiple PCs to the
Internet via broadband Cable modem or xDSL box and become your best partner for your network
solution.
1.2
Physical Features of ZSR0104C SERIES
Auto-Sensing Ethernet Switch
ZSR0104C SERIES is equipped with a 4-port switch featuring
auto-detect
10/100Mbps and
auto-crossover
. You can use either a Straight-Through or a Crossover cable to connect your
client PC to the LAN port of ZSR0104C SERIES.
10 / 100 Mbps Ethernet WAN
The 10 / 100 Mbps Ethernet WAN port is connected to the Internet via a Cable modem or
xDSL box or PPTP.
Reload Button
You can use the hardware Reload button to restore the factory default settings into ZSR0104C
SERIES.
1.3 Non-Physical Features of ZSR0104C SERIES
Network Address Translation (NAT)/Broadband Switch
ZSR0104C SERIES can translate the source IP address of a LAN client to the IP address of a
WAN client before forwarding a packet from the LAN to the WAN. When the packet returns,
NAT translates the destination address from a WAN client to the address of a LAN client
before forwarding the packet back to the LAN client. When only one WAN IP address is
available, NAT can translate the only WAN IP address into multiple LAN IP addresses for the

LAN clients. Therefore the LAN clients “
share”
the only one WAN IP address, and it is called
Broadband Switch
.
Firewall
ZSR0104C SERIES provides prevents Ping and TCP/UDP Echo Attack, Hacker’s Scan, and
Denial of Service (DoS). Also it offers Service Filter and URL Filter (by Keyword).
Dynamic DNS
Dynamic DNS (Domain Name System) allows you to register and obtain a fixed domain name
from DDNS service providers that ZSR0104C SERIES supports. When your ZSR0104C
SERIES obtains a dynamic public IP address, your ZSR0104C SERIES will inform the DDNS
service provider an updated IP address. Any a connection toward your domain name will be
mapped to the updated IP address by your DDNS service provider. You can be found easily by
connecting to your fixed domain name.
Virtual Server (Port Forwarding)
ZSR0104C SERIES can forward the service packet specified with a port number to the LAN
host specified by the LAN IP address. In other words, ZSR0104C SERIES can open the port
for the service with specified port number and then “
forward”
the port to a LAN host. Thus it
is called
Port Forwarding
, too.
VPN Pass-Through
In a Virtual Private Network, ZSR0104C SERIES supports the tunneling of Point-to-Point
Tunneling Protocol (PPTP) packet and allows it to enter the LAN that is the endpoint of the
VPN.
Special Application
Certain Internet applications use multiple ports, port ranges, dynamically assigned ports, and
special protocols. ZSR0104C SERIES supports the transparent pass-through of these special
applications, including FTP, ICMP, NetMeeting / H.323, Real Radio, Quick Time, MSN
Messenger, etc. and many popular Internet Games.
Public DMZ Host
Public DMZ Host is a device with a public IP address on the LAN side. ZSR0104C SERIES
provides the tunnel service for data traffic between the Public DMZ Host and the Internet.
Local DMZ Host
Local DMZ Host is a device with the private IP address on the LAN side. ZSR0104C SERIES
can forward the traffic initiated from the Internet to the Local DMZ Host.
DHCP Client
ZSR0104C SERIES can work as DHCP client and obtain an IP address automatically from the
Internet Service Provider or a DHCP server on the WAN side.
DHCP Server
As DHCP server, ZSR0104C SERIES can automatically assign TCP/IP settings to each client
PC on the LAN side and remember each client’s IP address corresponding to the client’s
MAC address. When ZSR0104C SERIES assigns TCP/IP settings in the next time, the LAN

client will receive the same LAN IP address.
Remote Management
ZSR0104C SERIES can be configured and managed from the WAN side via a specific port.
MAC Clone
ZSR0104C SERIES allows users to specify the MAC address of the Network Interface Card if
Internet Service Provider has the requirement.
Web-Based Setup
ZSR0104C SERIES can be managed through the Web browser in a LAN client PC connected
to ZSR0104C SERIES or the Internet.
