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
