By implementing PPPoE directly on the NBG4604 (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the NBG4604 does that part of the task. Furthermore, with NAT, all of the LAN's computers will have Internet access.
Page 47: Pptp Connection
PPTP supports on-demand, multi-protocol, and virtual private networking over public networks, such as the Internet. Refer to the appendix for more information on PPTP.

Similar to the way houses on a street share a common street name, so too do computers on a LAN share one common network number. Where you obtain your network number depends on your particular situation. If the ISP or your network administrator assigns you a block of registered IP NBG4604 User’s Guide...
Page 50: Dns Server Address Assignment
Once you have decided on the network number, pick an IP address that is easy to remember, for instance, 192.168.1.1, for your NBG4604, but make sure that no other device on your network is using that IP address.
Page 51: Wan Ip And Dns Server Address Assignment
The DNS server is extremely important because without it, you must know the IP address of a computer before you can access it. The NBG4604 uses a system DNS server (in the order you specify here) to resolve domain names for DDNS and the time server.
Page 52: Wan Mac Address
This screen allows users to configure the WAN port's MAC address by either using the NBG4604’s MAC address, copying the MAC address from a computer on your LAN or manually entering a MAC address. Once it is successfully configured, the address will be copied to configuration file.

H A P T E R 8.1 Overview This chapter discusses the NBG4604’s WAN screens. Use these screens to configure your NBG4604 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.
Page 102: What You Need To Know
(and service name) for user authentication. WAN IP Address The WAN IP address is an IP address for the NBG4604, which makes it accessible from an outside network. It is used by the NBG4604 to communicate with other devices in other networks. It can be static (fixed) or dynamically assigned by the ISP each time the NBG4604 tries to access the Internet.
Page 103: Multicast
NBG4604 supports both IGMP version 1 (IGMP-v1) and IGMP version 2 (IGMP- v2). At start up, the NBG4604 queries all directly connected networks to gather group membership. After that, the NBG4604 periodically updates this information. IP multicasting can be enabled/disabled on the NBG4604 LAN and/or WAN interfaces in the Web Configurator (LAN;...

Page 217 You can “borrow” one of the host ID bits to divide the network 192.168.1.0 into two separate sub-networks. The subnet mask is now 25 bits (255.255.255.128 or /25). The “borrowed” host ID bit can have a value of either 0 or 1, allowing two subnets; 192.168.1.0 /25 and 192.168.1.128 /25. NBG4604 User’s Guide...
Page 218 Similarly, to divide a 24-bit address into four subnets, you need to “borrow” two host ID bits to give four possible combinations (00, 01, 10 and 11). The subnet mask is 26 bits (11111111.11111111.11111111.11000000) or 255.255.255.192. NBG4604 User’s Guide...

Network Address Translation (NAT) on the NBG4604. Once you have decided on the network number, pick an IP address for your NBG4604 that is easy to remember (for instance, 192.168.1.1) but make sure that no other device on your network is using that IP address.
Page 222 Appendix A IP Addresses and Subnetting that you entered. You don't need to change the subnet mask computed by the NBG4604 unless you are instructed to do otherwise. Private IP Addresses Every machine on the Internet must have a unique address. If your networks are isolated from the Internet (running only between two branch offices, for example) you can assign any IP addresses to the hosts without problems.
