You should have at least a basic knowledge of TCP/IP networking concepts and topology. Related Documentation • Quick Start Guide The Quick Start Guide is designed to help you get up and running right away. It contains information on setting up your network and configuring for Internet access. • Supporting Disc Refer to the included CD for support documents. [. . . ] Use these screens to configure your NBG-419N for Internet access. A WAN (Wide Area Network) connection is an outside connection to another network or the Internet. It connects your private networks such as a LAN (Local Area Network) and other networks, so that a computer in one location can communicate with computers in other locations. Figure 78 LAN and WAN 12. 2 What You Can Do • Use the Internet Connection screen (Section 12. 4 on page 122) to enter your ISP information and set how the computer acquires its IP, DNS and WAN MAC addresses. • Use the Advanced screen (Section 12. 5 on page 132) to enable multicasting, configure Windows networking and bridge. • Use IGMP Snooping screen (Section 12. 6 on page 132) to enable IGMP snooping in the LAN ports. NBG-419N User’s Guide 119 Chapter 12 WAN 12. 3 What You Need To Know The information in this section can help you configure the screens for your WAN connection, as well as enable/disable some advanced features of your NBG-419N. 12. 3. 1 Configuring Your Internet Connection Encapsulation Method Encapsulation is used to include data from an upper layer protocol into a lower layer protocol. To set up a WAN connection to the Internet, you need to use the same encapsulation method used by your ISP (Internet Service Provider). If your ISP offers a dial-up Internet connection using PPPoE (PPP over Ethernet) or PPTP (Point-to-Point Tunneling Protocol), they should also provide a username and password (and service name) for user authentication. WAN IP Address The WAN IP address is an IP address for the NBG-419N, which makes it accessible from an outside network. It is used by the NBG-419N to communicate with other devices in other networks. It can be static (fixed) or dynamically assigned by the ISP each time the NBG-419N tries to access the Internet. If your ISP assigns you a static WAN IP address, they should also assign you the subnet mask and DNS server IP address(es) (and a gateway IP address if you use the Ethernet or ENET ENCAP encapsulation method). DNS Server Address Assignment Use Domain Name System (DNS) to map a domain name to its corresponding IP address and vice versa, for instance, the IP address of www. zyxel. com is 204. 217. 0. 2. The DNS server is extremely important because without it, you must know the IP address of a computer before you can access it. The NBG-419N can get the DNS server addresses in the following ways. 1 The ISP tells you the DNS server addresses, usually in the form of an information sheet, when you sign up. If your ISP gives you DNS server addresses, manually enter them in the DNS server fields. If your ISP dynamically assigns the DNS server IP addresses (along with the NBG419N’s WAN IP address), set the DNS server fields to get the DNS server address from the ISP. 2 120 NBG-419N User’s Guide Chapter 12 WAN WAN MAC Address The MAC address screen allows users to configure the WAN port's MAC address by either using the factory default or cloning the MAC address from a computer on your LAN. Choose Factory Default to select the factory assigned default MAC Address. Otherwise, click Clone the computer's MAC address - IP Address and enter the IP address of the computer on the LAN whose MAC you are cloning. Once it is successfully configured, the address will be copied to configuration file. It is recommended that you clone the MAC address prior to hooking up the WAN Port. 12. 3. 2 Multicast Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender - 1 recipient) or Broadcast (1 sender - everybody on the network). Multicast delivers IP packets to a group of hosts on the network - not everybody and not just 1. Figure 79 Multicast Example In the multicast example above, systems A and D comprise one multicast group. In multicasting, the server only needs to send one data stream and this is delivered to systems A and D. IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to establish membership in a multicast group - it is not used to carry user data.
