Chapter 1 Introduction This Chapter provides an overview of the Broadband Router's features and capabilities. 1 Congratulations on the purchase of your new Broadband Router. The Broadband Router is a multi-function device providing the following services: 4 Port Switching hub (10/100BaseT). Shared Internet access via an DSL or Cable modem.
CNet Technology Inc Broadband Router User Guide Internet Access Features • Shared Internet Access. All users on the LAN can access the Internet through the Broadband Router, using only a single external IP Address. The local (invalid) IP Addresses are hidden from external sources. This process is called NAT (Network Address Translation). • ADSL & Cable Modem Support. The Broadband Router has a 10BaseT Ethernet port • PPPoE Support.
CNet Technology Inc Introduction NAT Firewall Protection The firewall protection provided by the Broadband Router is an intrinsic side effect of NAT (Network Address Translation). All users on the LAN share a single external IP address. From the external viewpoint, there is no network, only a single device. For internal users, the Broadband Router acts as a “transparent proxy server”, translating the multiple internal IP addresses into a single external IP address.

6 Chapter 6 Routing This Chapter explains the Routing features of the Broadband Router. Overview While the Broadband Router includes a standard (static) routing table, this feature can be completely ignored if you do not have a router in your LAN. If you DO have a router, it is necessary to configure BOTH the Router and the Routing table in the Broadband Router correctly, as described in the following sections.
CNet Technology Inc Routing Routing Table Data An entry in the routing table is required for each LAN segment on your Network, other than the segment to which this device is attached. The data in the Routing Table is as follows. Destination IP Address The network address of the remote LAN segment. For standard class "C" LANs, the network address is the first 3 fields of this Destination IP Address. The 4th (last) field can be left at 0. Network Mask The Network Mask used on the remote LAN segment.
CNet Technology Inc Broadband Router User Guide Router Configuration It is essential that all IP packets for devices not on the local LAN be passed to the Broadband Router, so that they can be forwarded to the external LAN, WAN, or Internet. To achieve this, the local LAN must be configured to use the Broadband Router as the Default Route or Default Gateway. Local Router The local router is the Router installed on the same LAN segment as the Broadband Router.
CNet Technology Inc Routing For the Broadband Router's Routing Table The Broadband Router requires 2 entries as follows. Entry 1 (Segment 1) Destination IP Address 192.168.1.0 Network Mask 255.255.255.0 (Standard Class C) Gateway IP Address 192.168.0.100 (Broadband Router's local Router) Interface LAN Metric 1 Entry 2 (Segment 2) Destination IP Address 192.168.2.0 Network Mask 255.255.255.0 Gateway IP Address 192.168.0.
Chapter 7 Device Options 7 This Chapter details the options available on the Broadband Router's "Options" screen. Overview An example Options screen is shown below. Figure 18: Options Screen Password Once a password is entered, it is required in order to change the device configuration. Passwords are case sensitive and can be up to 8 alphanumeric characters (no spaces or punctuation).
CNet Technology Inc Options NAT (Network Address Translation) NAT allows PCs on your LAN to share a single external (Internet) IP Address. This IP Address is supplied by your ISP. Use the following to determine whether or nor you need NAT. • For Internet access, NAT must be left On unless all PCs on your LAN have valid external IP Addresses. • If this device is not being used to provide shared Internet access, NAT is not normally required.
Chapter 8 Advanced Inter Internet 8 This Chapter explains how to use the "Advanced Internet" features. Overview For situations where the Broadband Router is being used to provide shared Internet access, the following advanced features are provided. • Special Internet Applications • Virtual Servers • DMZ This chapter contains details of the configuration and use of each of these features.
CNet Technology Inc Advanced Internet Special Internet Applications This feature is only required if you wish to use Internet applications which require 2-way communication, multiple connections, or combined TCP/UDP connections. Examples of such applications are Internet Videoconferencing, Telephony, Games Servers, and other special-purpose Servers. Generally, you will become aware of the need for this feature when an Internet application is unable to function correctly.
