PPPoE is an IETF (Internet Engineering Task Force) standard specifying how a host NBG-419N Users Guide Chapter 2 Connection Wizard personal computer interacts with a broadband modem (for example DSL, cable, wireless, etc.) to achieve access to high-speed data networks. For the service provider, PPPoE offers an access and authentication method that works with existing access control systems (for instance, RADIUS). tia One of the benefits of PPPoE is the ability to let end users access one of multiple network services, a function known as dynamic service selection. This enables the service provider to easily create and offer new IP services for specific users. en Operationally, PPPoE saves significant effort for both the subscriber and the ISP/ carrier, as it requires no specific configuration of the broadband modem at the subscriber's site. ny on Figure 8 Internet Connection Type: PPPoE fid By implementing PPPoE directly on the NBG-419N (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the NBG-419N does that part of the task.

Use the WPS Station screen (Section 11.9 on page 113) to add a wireless station using WPS. on Use the Scheduling screen (Section 11.10 on page 114) to set the times your wireless LAN is turned on and off. Use the WDS screen (Section 11.11 on page 115) to configure Wireless Distribution System on your NBG-419N. 11.3 What You Should Know ny Every wireless network must follow these basic guidelines. Every wireless client in the same wireless network must use the same SSID. The SSID is the name of the wireless network. It stands for Service Set IDentity. pa If two wireless networks overlap, they should use different channels. Like radio stations or television channels, each wireless network uses a specific channel, or frequency, to send and receive information. om Every wireless client in the same wireless network must use security compatible with the AP. Security stops unauthorized devices from using the wireless network. It can also protect the information that is sent in the wireless network. 11.3.1 Wireless Security Overview 100 The following sections introduce different types of wireless security you can set up in the wireless network. NBG-419N Users Guide Chapter 11 Wireless LAN 11.3.1.1 SSID tia Normally, the AP acts like a beacon and regularly broadcasts the SSID in the area. You can hide the SSID instead, in which case the AP does not broadcast the SSID. In addition, you should change the default SSID to something that is difficult to guess. en This type of security is fairly weak, however, because there are ways for unauthorized devices to get the SSID. In addition, unauthorized devices can still see the information that is sent in the wireless network. 11.3.1.2 MAC Address Filter fid Every wireless client has a unique identification number, called a MAC address.1 A MAC address is usually written using twelve hexadecimal characters2; for example, 00A0C5000002 or 00:A0:C5:00:00:02. To get the MAC address for each wireless client, see the appropriate Users Guide or other documentation. on You can use the MAC address filter to tell the AP which wireless clients are allowed or not allowed to use the wireless network. If a wireless client is allowed to use the wireless network, it still has to have the correct settings (SSID, channel, and security). If a wireless client is not allowed to use the wireless network, it does not matter if it has the correct settings. ny This type of security does not protect the information that is sent in the wireless network. Furthermore, there are ways for unauthorized devices to get the MAC address of an authorized wireless client. Then, they can use that MAC address to use the wireless network. 11.3.1.3 Encryption om pa Wireless networks can use encryption to protect the information that is sent in the wireless network. Encryption is like a secret code. If you do not know the secret code, you cannot understand the message. 1. Some wireless devices, such as scanners, can detect wireless networks but cannot use wireless networks. These kinds of wireless devices might not have MAC addresses. 2. Hexadecimal characters are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F. NBG-419N Users Guide 101 Chapter 11 Wireless LAN The types of encryption you can choose depend on the type of user authentication. Table 35 Types of Encryption for Each Type of Authentication NO AUTHENTICATION No Security tia Weakest WEP WPA-PSK WPA2-PSK en Strongest fid Usually, you should set up the strongest encryption that every wireless client in the wireless network supports. Suppose the wireless network has two wireless clients. Device A only supports WEP, and device B supports WEP and WPA-PSK. Therefore, you should set up WEP in the wireless network. on Note: It is recommended that wireless networks use WPA-PSK or stronger encryption. IEEE 802.1x and WEP encryption are better than none at all, but it is still possible for unauthorized devices to figure out the original information pretty quickly. When you select WPA2-PSK in your NBG-419N, you can also select an option (WPA Compatible) to support WPA as well. In this case, if some wireless clients support WPA and some support WPA2, you should set up WPA2-PSK (depending on the type of wireless network login) and select the WPA Compatible option in the NBG-419N. pa 11.3.1.4 WPS ny Many types of encryption use a key to protect the information in the wireless network. The longer the key, the stronger the encryption. Every wireless client in the wireless network must have the same key. om WiFi Protected Setup (WPS) is an industry standard specification, defined by the WiFi Alliance. WPS allows you to quickly set up a wireless network with strong security, without having to configure security settings manually. Depending on the devices in your network, you can either press a button (on the device itself, or in its configuration utility) or enter a PIN (Personal Identification Number) in the devices. Then, they connect and set up a secure network by themselves. See how to set up a secure wireless network using WPS in the Section 10.3 on page 89. 11.3.1.5 WDS 102 Wireless Distribution System or WDS security is used between bridged APs. It is independent of the security between the wired networks and their respective APs. If you do not enable WDS security, traffic between APs is not encrypted. When WDS security is enabled, both APs must use the same pre-shared key.

Use these screens to configure your NBG-419N for Internet access. pa ny Figure 78 LAN and WAN on 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. 12.2 What You Can Do om 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 Users 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. tia 12.3.1 Configuring Your Internet Connection en Encapsulation Method fid 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. on 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. ny 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 pa 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. om The NBG-419N can get the DNS server addresses in the following ways. 120 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 NBG419Ns WAN IP address), set the DNS server fields to get the DNS server address from the ISP. NBG-419N Users Guide Chapter 12 WAN WAN MAC Address tia 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. en 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 pa ny Figure 79 Multicast Example on fid 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. om 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. The NBG-419N supports both IGMP version 1 (IGMP-v1) and IGMP version 2 (IGMPv2). At start up, the NBG-419N queries all directly connected networks to gather group membership. After that, the NBG-419N periodically updates this information. IP multicasting can be enabled/disabled on the NBG-419N LAN and/or WAN NBG-419N Users Guide 121 Chapter 12 WAN interfaces in the Web Configurator (LAN; WAN). Select None to disable IP multicasting on these interfaces. tia 12.4 Internet Connection en Use this screen to change your NBG-419Ns Internet access settings. Click WAN from the Configuration menu.

PPPoE is an IETF standard (RFC 2516) specifying how a personal computer (PC) interacts with a broadband modem (DSL, cable, wireless, etc.) connection. The PPP over Ethernet option is for a dial-up connection using PPPoE. For the service provider, PPPoE offers an access and authentication method that works with existing access control systems (for example Radius). en One of the benefits of PPPoE is the ability to let you access one of multiple network services, a function known as dynamic service selection. This enables the service provider to easily create and offer new IP services for individuals. fid Operationally, PPPoE saves significant effort for both you and the ISP or carrier, as it requires no specific configuration of the broadband modem at the customer site. om pa ny on By implementing PPPoE directly on the NBG-419N (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the NBG-419N does that part of the task.

For outgoing packets, NAT maps private (local) IP addresses to globally unique ones required for communication with hosts on other networks.

In some cases, such as for unknown services or where one server can support more than one service (for example both FTP and web service), it might be better to specify a range of port numbers. on In addition to the servers for specified services, NAT supports a default server. A service request that does not have a server explicitly designated for it is forwarded to the default server. If the default is not defined, the service request is simply discarded.

With regular port forwarding you set a forwarding port in NAT to forward a service (coming in from the server on the WAN) to the IP address of a computer on the client side (LAN). The problem is that port forwarding only forwards a service to a single LAN IP address. In order to use the same service on a different LAN computer, you have to manually replace the LAN computer's IP address in the forwarding port with another LAN computer's IP address. pa ny Trigger port forwarding solves this problem by allowing computers on the LAN to dynamically take turns using the service. The NBG-419N records the IP address of a LAN computer that sends traffic to the WAN to request a service with a specific port number and protocol (a "trigger" port). When the NBG-419N's WAN port receives a response with a specific port number and protocol ("incoming" port), the NBG-419N forwards the traffic to the LAN IP address of the computer that sent the request. After that computers connection for that service closes, another computer on the LAN can use the service in the same manner. This way you do not need to configure a new IP address each time you want a different LAN computer to use the application. om To change your NBG-419Ns trigger port settings, click Network > NAT > Advanced.

For example, with the URL www.zyxel.com.tw/news/ pressroom.php, the domain name is www.zyxel.com.tw. en The file path is the characters that come after the first slash in the URL. For example, with the URL www.zyxel.com.tw/news/pressroom.php, the file path is news/pressroom.php. on fid Since the NBG-419N checks the URLs domain name (or IP address) and file path separately, it will not find items that go across the two. For example, with the URL www.zyxel.com.tw/news/pressroom.php, the NBG-419N would find tw in the domain name (www.zyxel.com.tw). It would also find news in the file path (news/pressroom.php) but it would not find tw/news. 20.4 Content Filter Screen Use this screen to restrict web features, add keywords for blocking and designate a trusted computer.
