NBG4604 User’s Guide 21CHAPTER 1 Introduction1.1 OverviewThis chapter introduces the main features and applications of the NBG4604.The NBG4604 extends the range of your existing wired network without additional wiring, providing easy network access to mobile users. You can set up a wireless network with other IEEE 802.11b/g/n compatible devices.A range of services such as a firewall and content filtering are also available for secure Internet computing.1.2 ApplicationsYour can create the following networks using the NBG4604:•Wired. You can connect network devices via the Ethernet ports of the NBG4604 so that they can communicate with each other and access the Internet.•Wireless. Wireless clients can connect to the NBG4604 to access network resources.•WAN. Connect to a broadband modem/router for Internet access.Figure 1 NBG4604 NetworkCompany Confidential
Chapter 1IntroductionNBG4604 User’s Guide221.3 Ways to Manage the NBG4604Use any of the following methods to manage the NBG4604.•WPS (Wi-Fi Protected Setup). You can use the WPS button or the WPS section of the Web Configurator to set up a wireless network with your ZyXEL Device.•Web Configurator. This is recommended for everyday management of the NBG4604 using a (supported) web browser.1.4 Good Habits for Managing the NBG4604Do the following things regularly to make the NBG4604 more secure and to manage the NBG4604 more effectively.•Change the password. Use a password that’s not easy to guess and that consists of different types of characters, such as numbers and letters.•Write down the password and put it in a safe place.•Back up the configuration (and make sure you know how to restore it). Restoring an earlier working configuration may be useful if the device becomes unstable or even crashes. If you forget your password, you will have to reset the NBG4604 to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the NBG4604. You could simply restore your last configuration.1.5 LEDsFigure 2 Front PanelThe following table describes the LEDs and the WPS button.Table 1 Front Panel LEDs and WPS ButtonLED COLOR STATUS DESCRIPTIONPOWERGreenOnThe NBG4604 is receiving power and functioning properly.

NBG4604 User’s Guide 25CHAPTER 2 The WPS Button2.1 OverviewYour NBG4604 supports WiFi Protected Setup (WPS), which is an easy way to set up a secure wireless network. 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. Each WPS connection works between two devices. Both devices must support WPS (check each device’s documentation to make sure). Depending on the devices you have, you can either press a button (on the device itself, or in its configuration utility) or enter a PIN (a unique Personal Identification Number that allows one device to authenticate the other) in each of the two devices. When WPS is activated on a device, it has two minutes to find another device that also has WPS activated. Then, the two devices connect and set up a secure network by themselves.For more information on using WPS, see Section 6.2.1 on page 63.Company Confidential

Chapter 4Connection WizardNBG4604 User’s Guide464.4.2 PPPoE ConnectionPoint-to-Point Protocol over Ethernet (PPPoE) functions as a dial-up connection. PPPoE is an IETF (Internet Engineering Task Force) standard specifying how a host 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). 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.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.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.Refer to the appendix for more information on PPPoE.Figure 16 Wizard Step 3: PPPoE ConnectionThe following table describes the labels in this screen.Table 12 Wizard Step 3: PPPoE ConnectionLABEL DESCRIPTIONISP Parameter for Internet AccessConnection Type Select the PPP over Ethernet option for a dial-up connection.Service Name Type the name of your service provider.User Name Type the user name given to you by your ISP.

Chapter 4Connection WizardNBG4604 User’s Guide 49The following table describes the labels in this screen4.4.5 WAN IP Address AssignmentEvery computer on the Internet must have a unique IP address. If your networks are isolated from the Internet, for instance, only between your two branch offices, you can assign any IP addresses to the hosts without problems. However, the Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of IP addresses specifically for private networks.You can obtain your IP address from the IANA, from an ISP or have it assigned by a private network. If you belong to a small organization and your Internet access is through an ISP, the ISP can provide you with the Internet addresses for your local networks. On the other hand, if you are part of a much larger organization, you should consult your network administrator for the appropriate IP addresses.Note: Regardless of your particular situation, do not create an arbitrary IP address; always follow the guidelines above. For more information on address assignment, please refer to RFC 1597, Address Allocation for Private Internets and RFC 1466, Guidelines for Management of IP Address Space.4.4.6 IP Address and Subnet MaskSimilar 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 Table 14 Wizard Step 3: Your IP AddressLABEL DESCRIPTIONGet automatically from your ISP Select this option If your ISP did not assign you a fixed IP address. This is the default selection. If you choose this option, skip directly to Section 4.4.9 on page 52.Use fixed IP address provided by your ISP Select this option if you were given IP address and/or DNS server settings by the ISP. The fixed IP address should be in the same subnet as your broadband modem or router. Back Click Back to return to the previous screen.Next Click Next to continue.

Chapter 4Connection WizardNBG4604 User’s Guide50addresses, follow their instructions in selecting the IP addresses and the subnet mask.If the ISP did not explicitly give you an IP network number, then most likely you have a single user account and the ISP will assign you a dynamic IP address when the connection is established. The Internet Assigned Number Authority (IANA) reserved this block of addresses specifically for private use; please do not use any other number unless you are told otherwise. Let's say you select 192.168.1.0 as the network number; which covers 254 individual addresses, from 192.168.1.1 to 192.168.1.254 (zero and 255 are reserved). In other words, the first three numbers specify the network number while the last number identifies an individual computer on that network.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.The subnet mask specifies the network number portion of an IP address. Your NBG4604 will compute the subnet mask automatically based on the IP address that you entered. You don't need to change the subnet mask computed by the NBG4604 unless you are instructed to do otherwise.4.4.7 DNS Server Address AssignmentUse DNS (Domain Name System) 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 NBG4604 can get the DNS server addresses in the following ways.1The 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, enter them in the DNS Server fields in the Wizard and/or WAN> Internet Connectionscreen.2If the ISP did not give you DNS server information, leave the DNS Server fields set to 0.0.0.0 in the Wizard screen and/or set to From ISP in the WAN>Internet Connection screen for the ISP to dynamically assign the DNS server IP addresses.Company Confidential

This example uses the NBG4604 as the AP and NWD210N as the wireless client which connects to a notebook. Note: The wireless client must be a WPS-aware device (for example, a WPS USB adapter or PCI card).Company Confidential
Chapter 6TutorialsNBG4604 User’s Guide64There are two WPS methods for creating a secure connection. This tutorial shows you how to do both.•Push Button Configuration (PBC) - create a secure wireless network simply by pressing a button. See Section 6.2.1.1 on page 64.This is the easier method.•PIN Configuration - create a secure wireless network simply by entering a wireless client's PIN (Personal Identification Number) in the NBG4604’s interface. See Section 6.2.1.2 on page 65. This is the more secure method, since one device can authenticate the other.6.2.1.1 Push Button Configuration (PBC)1Make sure that your NBG4604 is turned on and that it is within range of your computer. 2Make sure that you have installed the wireless client (this example uses the NWD210N) driver and utility in your notebook.3In the wireless client utility, find the WPS settings. Enable WPS and press the WPS button (Start or WPS button)4Log into NBG4604’s Web Configurator and press the Push Button button in the Network > Wireless Client >WPS Station screen. Note: Your NBG4604 has a WPS button located on its panel, as well as a WPS button in its configuration utility. Both buttons have exactly the same function; you can use one or the other.Note: It doesn’t matter which button is pressed first. You must press the second button within two minutes of pressing the first one. The NBG4604 sends the proper configuration settings to the wireless client. This may take up to two minutes. Then the wireless client is able to communicate with the NBG4604 securely. Company Confidential

NBG4604 User’s Guide 77CHAPTER 7 Wireless LAN7.1 OverviewThis chapter discusses how to configure the wireless network settings in your NBG4604. See the appendices for more detailed information about wireless networks.The following figure provides an example of a wireless network.Figure 40 Example of a Wireless NetworkThe wireless network is the part in the blue circle. In this wireless network, devices A and B are called wireless clients. The wireless clients use the access point (AP) to interact with other devices (such as the printer) or with the Internet. Your NBG4604 is the AP.Company Confidential
Chapter 7Wireless LANNBG4604 User’s Guide787.2 What You Can Do•Use the General screen (Section 7.4 on page 81) to enable the Wireless LAN, enter the SSID and select the wireless security mode.•Use the MAC Filter screen (Section 7.5 on page 87) to allow or deny wireless stations based on their MAC addresses from connecting to the NBG4604.•Use the Advanced screen (Section 7.6 on page 89) to allow intra-BSS networking and set the RTS/CTS Threshold.•Use the QoS screen (Section 7.7 on page 90) to ensure Quality of Service (QoS) in your wireless network.•Use the WPS screen (Section 7.8 on page 93) to quickly set up a wireless network with strong security, without having to configure security settings manually.•Use the WPS Station screen (Section 7.9 on page 94) to add a wireless station using WPS. •Use the Scheduling screen (Section 7.10 on page 95) to set the times your wireless LAN is turned on and off.•Use the WDS screen (Section 7.11 on page 96) to set the operating mode of your NBG4604 to AP + Bridge or Bridge Only and establish wireless links with other APs. 7.3 What You Should KnowEvery 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.•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.•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.7.3.1 Wireless Security OverviewThe following sections introduce different types of wireless security you can set up in the wireless network.Company Confidential
Chapter 7Wireless LANNBG4604 User’s Guide 797.3.1.1 SSIDNormally, 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.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.7.3.1.2 MAC Address FilterEvery 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 User’s Guide or other documentation.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.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.7.3.1.3 User AuthenticationYou can make every user log in to the wireless network before they can use it. This is called user authentication. However, every wireless client in the wireless network has to support IEEE 802.1x to do this.For wireless networks, there are two typical places to store the user names and passwords for each user.•In the AP: this feature is called a local user database or a local database.•In a RADIUS server: this is a server used in businesses more than in homes.If your AP does not provide a local user database and if you do not have a RADIUS server, you cannot set up user names and passwords for your users.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.Company Confidential
Chapter 7Wireless LANNBG4604 User’s Guide80Unauthorized devices can still see the information that is sent in the wireless network, even if they cannot use the wireless network. Furthermore, there are ways for unauthorized wireless users to get a valid user name and password. Then, they can use that user name and password to use the wireless network.Local user databases also have an additional limitation that is explained in the next section.7.3.1.4 EncryptionWireless 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.The types of encryption you can choose depend on the type of user authentication. (See Section 7.3.1.3 on page 79 for information about this.)For example if the wireless network has a RADIUS server, you can choose WPA or WPA2. If users do not log in to the wireless network, you can choose no encryption, Static WEP,WPA-PSK, or WPA2-PSK.Usually, you should set up the strongest encryption that every wireless client in the wireless network supports. For example, suppose the AP does not have a local user database, and you do not have a RADIUS server. Therefore, there is no user authentication. Suppose the wireless network has two wireless clients. Device A only supports WEP, and device B supports WEP and WPA. Therefore, you should set up Static WEP in the wireless network.Note: It is recommended that wireless networks use WPA-PSK, WPA, 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.Note: It is not possible to use WPA-PSK, WPA or stronger encryption with a local user database. In this case, it is better to set up stronger encryption with no authentication than to set up weaker encryption with the local user database.When you select WPA2 or WPA2-PSK in your NBG4604, 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 or Table 23 Types of Encryption for Each Type of AuthenticationNO AUTHENTICATION RADIUS SERVERWeakest No SecurityWPAStatic WEPWPA-PSKStrongest WPA2-PSKWPA2Company Confidential
Chapter 7Wireless LANNBG4604 User’s Guide 81WPA2 (depending on the type of wireless network login) and select the WPACompatible option in the NBG4604.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.7.3.1.5 WPSWiFi 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 6.2.1 on page 63.7.4 General Wireless LAN Screen Use this screen to enable the Wireless LAN, enter the SSID and select the wireless security mode.Note: If you are configuring the NBG4604 from a computer connected to the wireless LAN and you change the NBG4604’s SSID, channel or security settings, you will lose your wireless connection when you press Apply to confirm. You must then change the wireless settings of your computer to match the NBG4604’s new settings.Click Network > Wireless LAN to open the General screen.Figure 41 Network > Wireless LAN > General Company Confidential

NBG4604 User’s Guide 101CHAPTER 8 WAN8.1 OverviewThis 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.Figure 55 LAN and WANSee the chapter about the connection wizard for more information on the fields in the WAN screens.8.2 What You Can Do•Use the Internet Connection screen (Section 8.4 on page 105) to enter your ISP information and set how the computer acquires its IP, DNS and WAN MAC addresses.•Use the Advanced screen (Section 8.5 on page 111) to enable multicasting, configure Windows networking and bridge.Company Confidential
Chapter 8WANNBG4604 User’s Guide1028.3 What You Need To KnowThe information in this section can help you configure the screens for your WAN connection, as well as enable/disable some advanced features of your NBG4604.8.3.1 Configuring Your Internet ConnectionEncapsulation MethodEncapsulation 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 AddressThe 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.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 AssignmentUse 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 NBG4604 can get the DNS server addresses in the following ways.1The 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.2If your ISP dynamically assigns the DNS server IP addresses (along with the NBG4604’s WAN IP address), set the DNS server fields to get the DNS server address from the ISP. Company Confidential
Chapter 8WANNBG4604 User’s Guide 103WAN MAC AddressThe 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.8.3.2 MulticastTraditionally, 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 56 Multicast ExampleIn 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 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; WAN). Select None to disable IP multicasting on these interfaces.Company Confidential
Chapter 8WANNBG4604 User’s Guide1048.3.3 NetBIOS over TCP/IP NetBIOS (Network Basic Input/Output System) are TCP or UDP broadcast packets that enable a computer to connect to and communicate with a LAN. For some dial-up services such as PPPoE or PPTP, NetBIOS packets cause unwanted calls. However it may sometimes be necessary to allow NetBIOS packets to pass through to the WAN in order to find a computer on the WAN.8.3.4 Auto-BridgeIn the rear panel of your NBG4604, you can see four LAN ports (1 to 4) and one WAN port. The WAN port is for your Internet access connection, and the LAN ports are for your network devices. The WAN port has a different IP address from the LAN ports. When you enable auto-bridging in your NBG4604, all five ports (4 LAN ports and the WAN port) share the same IP address as shown in the figure below.Figure 57 Autobridging ExampleThis might happen if you put the NBG4604 behind a NAT router that assigns it this IP address. When the NBG4604 is in auto-bridge mode, the NBG4604 acts as an AP and all the interfaces (LAN, WAN and WLAN) are bridged. In this mode, your NAT, DHCP server and firewall on the NBG4604 are not available. You do not have to reconfigure them if you return to router mode.Auto-bridging only works under the following conditions:•The WAN IP must be 192.168.x.y (where x and y must be from zero to nine). If the LAN IP address and the WAN IP address are in the same subnet but x or y is greater than nine, the device operates in router mode (with firewall available).•The device must be in Router Mode (see Chapter 24 on page 193 for more information) for auto-bridging to become active.IP Address: 192.168.1.20Company Confidential

Chapter 8WANNBG4604 User’s Guide 107One 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.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.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 LANs’ computers will have access.This screen displays when you select PPPoE encapsulation.Figure 59 Network > WAN > Internet Connection: PPPoE EncapsulationThe following table describes the labels in this screen.Table 39 Network > WAN > Internet Connection: PPPoE EncapsulationLABEL DESCRIPTIONISP Parameters for Internet AccessConnection Type Select PPP over Ethernet if you connect to your Internet via dial-up.Service Name Type the PPPoE service name provided to you.

NBG4604 User’s Guide 123CHAPTER 11 Network Address Translation(NAT)11.1 Overview This chapter discusses how to configure NAT on the NBG4604.NAT (Network Address Translation - NAT, RFC 1631) is the translation of the IP address of a host in a packet. For example, the source address of an outgoing packet, used within one network is changed to a different IP address known within another network.Each packet has two addresses – a source address and a destination address. For outgoing packets, NAT maps private (local) IP addresses to globally unique ones required for communication with hosts on other networks. It replaces the original IP source address in each packet and then forwards it to the Internet. The NBG4604 keeps track of the original addresses and port numbers so incoming reply packets can have their original values restored. The following figure illustrates this.Figure 68 NAT ExampleFor more information on IP address translation, refer to RFC 1631,The IP Network Address Translator (NAT).Company Confidential
Chapter 11Network Address Translation (NAT)NBG4604 User’s Guide124Note: You must create a firewall rule in addition to setting up NAT, to allow traffic from the WAN to be forwarded through the NBG4604.11.2 What You Can Do•Use the General screen (Section 11.3 on page 124) to enable NAT and set a default server.•Use the Application screen (Section 11.4 on page 125) to change your NBG4604’s port forwarding settings.•Use the Advanced screen (Section 11.5 on page 128) to change your NBG4604’s trigger port settings.11.3 General NAT ScreenUse this screen to enable NAT and set a default server.

Chapter 11Network Address Translation (NAT)NBG4604 User’s Guide 12511.4 NAT Application Screen Use the Application screen to forward incoming service requests to the server(s) on your local network. You may enter a single port number or a range of port numbers to be forwarded, and the local IP address of the desired server. The port number identifies a service; for example, web service is on port 80 and FTP on port 21. 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.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.Note: Many residential broadband ISP accounts do not allow you to run any server processes (such as a Web or FTP server) from your location. Your ISP may periodically check for servers and may suspend your account if it discovers any active services at your location. If you are unsure, refer to your ISP.Port forwarding allows you to define the local servers to which the incoming services will be forwarded. To change your NBG4604’s port forwarding settings, click Network > NAT > Application. The screen appears as shown.Note: If you do not assign a Default ServerIP address in the NAT >General screen, the NBG4604 discards all packets received for ports that are not specified in this screen or remote management.Server IP Address In addition to the servers for specified services, NAT supports a default server.

Chapter 11Network Address Translation (NAT)NBG4604 User’s Guide12811.5 NAT Advanced ScreenSome services use a dedicated range of ports on the client side and a dedicated range of ports on the server side. 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. Trigger port forwarding solves this problem by allowing computers on the LAN to dynamically take turns using the service. The NBG4604 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 NBG4604's WAN port receives a response with a specific port number and protocol ("incoming" port), the NBG4604 forwards the traffic to the LAN IP address of the computer that sent the request. After that computer’s 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.To change your NBG4604’s trigger port settings, click Network > NAT > Advanced. The screen appears as shown.Note: Only one LAN computer can use a trigger port (range) at a time.Figure 71 Network > NAT > Advanced Company Confidential

The NBG4604's purpose is to allow a private Local Area Network (LAN) to be securely connected to the Internet. The NBG4604 can be used to prevent theft, destruction and modification of data, as well as log events, which may be important to the security of your network. The NBG4604 is installed between the LAN and a broadband modem connecting to the Internet. This allows it to act as a secure gateway for all data passing between the Internet and the LAN.The NBG4604 has one Ethernet WAN port and four Ethernet LAN ports, which are used to physically separate the network into two areas.The WAN (Wide Area Network) port attaches to the broadband (cable or DSL) modem to the Internet.The LAN (Local Area Network) port attaches to a network of computers, which needs security from the outside world. These computers will have access to Internet services such as e-mail, FTP and the World Wide Web. However, "inbound access" is not allowed (by default) unless the remote host is authorized to use a specific service.Company Confidential

ICMP uses Internet Protocol (IP) datagrams, but the messages are processed by the TCP/IP software and directly apparent to the application user. Respond to Ping on The NBG4604 will not respond to any incoming Ping requests when Disable is selected. Select LAN to reply to incoming LAN Ping requests.Select WAN to reply to incoming WAN Ping requests. Otherwise select LAN & WAN to reply to all incoming LAN and WAN Ping requests. Do not respond to requests for unauthorized servicesSelect this option to prevent hackers from finding the NBG4604 by probing for unused ports. If you select this option, the NBG4604 will not respond to port request(s) for unused ports, thus leaving the unused ports and the NBG4604 unseen. By default this option is not selected and the NBG4604 will reply with an ICMP Port Unreachable packet for a port probe on its unused UDP ports, and a TCP Reset packet for a port probe on its unused TCP ports. Note that the probing packets must first traverse the NBG4604's firewall mechanism before reaching this anti-probing mechanism. Therefore if the firewall mechanism blocks a probing packet, the NBG4604 reacts based on the firewall policy, which by default, is to send a TCP reset packet for a blocked TCP packet. You can use the command "sys firewall tcprst rst [on|off]" to change this policy. When the firewall mechanism blocks a UDP packet, it drops the packet without sending a response packet.Apply Click Apply to save the settings.

NBG4604 User’s Guide 139CHAPTER 14Content Filtering14.1 OverviewThis chapter provides a brief overview of content filtering using the embedded web GUI.Internet content filtering allows you to create and enforce Internet access policies tailored to your needs. Content filtering is the ability to block certain web features or specific URL keywords.14.2 What You Can DoUse the Filter (Section 14.4 on page 140) screen to restrict web features, add keywords for blocking and designate a trusted computer.14.3 What You Need To KnowContent filtering allows you to block certain web features, such as cookies, and/or block access to specific web sites. For example, you can configure one policy that blocks John Doe’s access to arts and entertainment web pages.14.3.1 Content Filtering ProfilesA content filtering profile conveniently stores your custom settings for the following features.Restrict Web FeaturesThe NBG4604 can disable web proxies and block web features such as ActiveX controls, Java applets and cookies.Company Confidential
Chapter 14Content FilteringNBG4604 User’s Guide140Keyword Blocking URL CheckingThe NBG4604 checks the URL’s domain name (or IP address) and file path separately when performing keyword blocking. The URL’s domain name or IP address is the characters that come before the first slash in the URL. For example, with the URL www.zyxel.com.tw/news/pressroom.php, the domain name is www.zyxel.com.tw.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.Since the NBG4604 checks the URL’s 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 NBG4604 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”.14.4 Filter ScreenUse this screen to restrict web features, add keywords for blocking and designate a trusted computer.

NBG4604 User’s Guide 143CHAPTER 15Static Route15.1 OverviewThis chapter shows you how to configure static routes for your NBG4604.Each remote node specifies only the network to which the gateway is directly connected, and the NBG4604 has no knowledge of the networks beyond. For instance, the NBG4604 knows about network N2 in the following figure through remote node Router 1. However, the NBG4604 is unable to route a packet to network N3 because it doesn't know that there is a route through the same remote node Router 1 (via gateway Router 2). The static routes are for you to tell the NBG4604 about the networks beyond the remote nodes.Figure 78 Example of Static Routing Topology15.2 What You Can Do•Use the IP Static Route screen (Section 15.3 on page 144) to view existing static route rules.•Use the Static Route Setup screen (Section 15.3.1 on page 145) to add or edit a static route rule.Company Confidential

Fill in the required information for each static route.Figure 80 Management > Static Route > IP Static Route: Static Route SetupThe following table describes the labels in this screen.Table 54 Management > Static Route > IP Static Route: Static Route SetupLABEL DESCRIPTIONRoute Name Enter the name of the IP static route. Leave this field blank to delete this static route.Active This field allows you to activate/deactivate this static route.Destination IP Address This parameter specifies the IP network address of the final destination. Routing is always based on network number. If you need to specify a route to a single host, use a subnet mask of 255.255.255.255 in the subnet mask field to force the network number to be identical to the host ID.IP Subnet Mask Enter the IP subnet mask here.Gateway IP Address Enter the IP address of the gateway. The gateway is an immediate neighbor of your NBG4604 that will forward the packet to the destination. On the LAN, the gateway must be a router on the same segment as your NBG4604; over the WAN, the gateway must be the IP address of one of the Remote Nodes.Metric Metric represents the “cost” of transmission for routing purposes. IP routing uses hop count as the measurement of cost, with a minimum of 1 for directly connected networks. Enter a number that approximates the cost for this link. The number need not be precise, but it must be between 1 and 15. In practice, 2 or 3 is usually a good number.

NBG4604 User’s Guide 147CHAPTER 16Bandwidth Management16.1 Overview This chapter contains information about configuring bandwidth management and editing rules.ZyXEL’s Bandwidth Management allows you to specify bandwidth management rules based on an application. In the figure below, uplink traffic goes from the LAN device (A) to the WAN device (B). Bandwidth management is applied before sending the packets out to the WAN. Downlink traffic comes back from the WAN device (B) to the LAN device (A). Bandwidth management is applied before sending the traffic out to LAN.Figure 81 Bandwidth ManagementYou can allocate specific amounts of bandwidth capacity (bandwidth budgets) to individual applications (like VoIP, Web, FTP, and E-mail for example).16.2 What You Can Do•Use the General screen (Section 16.4 on page 148) to enable bandwidth management and assign uplink/downlink limits.•Use the Advanced screen (Section 16.5 on page 149) to configure bandwidth management rules for the pre-defined services and applications.AB-> VOIP-> FTP-> HTTP-> Chat, EmailCompany Confidential
