1 Chapter 1: Introduction Introduction to your Router Thank you for purchasing BiPAC 7800NEXL router, an all-in-one ADSL2+ Router with wireless-N technology. The BiPAC 7800NEXL is an ADSL2+ Router that offers users affordable expanded wireless coverage and speedy Internet connection. By supporting Internet Protocol, IPv6, this All-in-One Router allows users to make internet connections between existing IPv4 networks and future IPv6 network upgrades when greater security, high quality QoS and larger addressing are required. With an integrated 802.11n Access Point, the BiPAC 7800NEXL can automatically adopt an optimal connection to deliver smooth, constant signal reception even if obstacles are present. Robust Firewall security is featured to protect Internet access against hacker attacks. The Quality of Service and VLAN enables intelligent steaming for HD video or multiple applications such as music downloads, online gaming, video streaming and file sharing simultaneously. Optimal Wireless Speeds and Coverage With an integrated 802.11n Wireless Access Point, this router supports a data rates up to 300Mbps and delivers up to 6 times the speed and 3 times the wireless coverage of an 802.11b/g network device. If the network requires wider coverage, the built-in Wireless Distribution System (WDS) repeater function allows users to expand the wireless network without the need for any external wires or cables. Jitter-free, Reliable Net Traffic Quality of Service (QoS) gives full control over outgoing data traffic. Priority can be assigned by the router to ensure that important transmissions like gaming packets, VoIP calls or IPTV / streaming content passes through the router at lightning speed, even when there is heavy Internet traffic. The transfer speed of different types of outgoing data passing through the router is also controlled to ensure that users do not saturate bandwidth with their browsing activities. The VLAN support is also capable of establishing reliable high-speed transmissions for wide bandwidth applications such as IPTV, VOD, or online gaming without consuming bandwidth. High-speed Internet Access The BiPAC 7800NEXL is compliant with worldwide ADSL standards, and supports download rates of up to 12 / 24Mbps using ADSL2 / 2+, 8Mbps using ADSL and an upload rate of up to 1Mbps. The integrated Annex M standard supports ADSL2 / 2+ for higher uploads by doubling the upload data rate. The 4-port Ethernet Switch incorporated into the BiPAC 7800NEXL enables users to connect to multiple computers or wired-Ethernet devices easily and enjoy blistering LAN transmission for multimedia applications such as interactive gaming, IPTV video streaming and real-time audio. Simple Setup, Ease of Management Easy Sign-On (EZSO), WPS push button and Auto-scan ADSL settings allow users to manage the device functions effortlessly! The user-friendly, web-based user interface makes installing and managing the BiPAC 7800NEXL extremely easy. With support for both DHCP client and server, system administrators can manage IP assignment without having to reconfigure other stations and fitting the router into existing network environments.

2 IPv6 supported Internet Protocol version 6 (IPv6) is a version of the Internet Protocol that is designed to succeed IPv4. IPv6 has a vastly larger address space than IPv4. This results from the use of a 128-bit address, whereas IPv4 uses only 32 bits. The new address space thus supports 2128 (about 3.4×1038) addresses. This expansion provides flexibility in allocating addresses and routing traffic and eliminates the primary need for network address translation (NAT), which gained widespread deployment as an effort to alleviate IPv4 address exhaustion. IPv6 also implements new features that simplify aspects of address assignment (stateless address autoconfiguration) and network renumbering (prefix and router announcements) when changing Internet connectivity providers. The IPv6 subnet size has been standardized by fixing the size of the host identifier portion of an address to 64 bits to facilitate an automatic mechanism for forming the host identifier from Link Layer media addressing information (MAC address). Network security is integrated into the design of the IPv6 architecture. Internet Protocol Security (IPsec) was originally developed for IPv6, but found widespread optional deployment first in IPv4 (into which it was back-engineered). The IPv6 specifications mandate IPsec implementation as a fundamental interoperability requirement. VLAN MUX A Virtual LAN, commonly known as a VLAN, is a group of hosts with the common set of requirements that communicate as if they were attached to the same broadcast domain, regardless of the physical location. A VLAN has the same attributes as a physical LAN, but it allows for end stations to be grouped together even if they are not located on the same network switch. The most commonly used Virtual LAN is defined by 802.1Q tagging protocol, which expended the original Ethernet frame header to include VLAN ID (tag) and priority bits. With the support of network equipments, multiple virtual networks can coexist over the same physical network. Ethernet frames are used to transfer data over ADSL line when bridging, MER or PPPoE mode is used. While the DSL connection we usually configured is to use a PVC match a single service, PPPoE PPPoA, bridging, etc. With the VLAN tag, we can make virtual interfaces to create multiple separate WAN connections within the same PVC. It allows multiple services over the same PVC. The VLAN Mux feature is designed for this purpose. For example, you have an ATM interface, PVC with VPI/VCI 8/35, you can set the PPPoE, IPoE, and Bridge connection via the PVC without respectively assigning the three services to three different PVCs. Virtual AP A “Virtual Access Point” is a logical entity that exists within a physical Access Point (AP). When a single physical AP supports multiple “Virtual APs”, each Virtual AP appears to stations (STAs) to be an independent physical AP, even though only a single physical AP is present. For example, multiple Virtual APs might exist within a single physical AP, each advertising a distinct SSID and capability set. Alternatively, multiple Virtual APs might advertise the same SSID but a different capability set – allowing access to be provided via Web Portal, WEP, and WPA simultaneously. Where APs are shared by multiple providers, Virtual APs provide each provider with separate authentication and accounting data for their users, as well as diagnostic information, without sharing sensitive management traffic or data between providers. You can enable the virtual AP. Web Based GUI It supports web based GUI for configuration and management. It is user-friendly and comes with online help. It also supports remote management capability for remote users to configure and manage this product.

12 Cabling One of the most common causes of problem is bad cabling or ADSL line(s). Make sure that all connected devices are turned on. On the front panel of your router is a bank of LEDs. Verify that the LAN Link and ADSL line LEDs are lit. If they are not, verify if you are using the proper cables. If the error persists, you may have a hardware problem. In this case you should contact technical support. Ensure that all other devices connected to the same telephone line as your router (e.g. telephones, fax machines, analogue modems) have a line filter connected between them and the wall socket (unless you are using a Central Splitter or Central Filter installed by a qualified and licensed electrician), and ensure that all line filters are correctly installed and the right way around. Missing line filters or line filters installed the wrong way around can cause problems with your ADSL connection, including causing frequent disconnections. If you have a back-to-base alarm system you should contact your security provider for a technician to make any necessary changes.

13 Chapter 3: Basic Installation The router can be configured through your web browser. A web browser is included as a standard application in the following operating systems: Linux, Mac OS, Windows 7 / 98 / NT / 2000 / XP / Me / Vista, etc. The product provides an easy and user-friendly interface for configuration. Please check your PC network components. The TCP/IP protocol stack and Ethernet network adapter must be installed. If not, please refer to your Windows-related or other operating system manuals. There are ways to connect the router, either through an external repeater hub or connect directly to your PCs. However, make sure that your PCs have an Ethernet interface installed properly prior to connecting the router device. You ought to configure your PCs to obtain an IP address through a DHCP server or a fixed IP address that must be in the same subnet as the router. The default IP address of the router is 192.168.1.254 and the subnet mask is 255.255.255.0 (i.e. any attached PC must be in the same subnet, and have an IP address in the range of 192.168.1.1 to 192.168.1.253). The best and easiest way is to configure the PC to get an IP address automatically from the router using DHCP. If you encounter any problem accessing the router web interface it is advisable to uninstall your firewall program on your PCs, as they can cause problems accessing the IP address of the router.

While in contrast to Default connection mode, one PVC can only hold one service, if you want to more than one service over one PVC, you should apply from your ISP more PVCs to meet your needs.

72 LAN - Local Area Network A Local Area Network (LAN) is a shared communication system network where many computers are connected. This type of network is area defined and is usually limited to a confined region within a building or just within the same storey of a building. Parameters Group Name: here group refers to the group you set in Interface Grouping section, you can set the parameters for the specific group. Select the group by the drop-down box. For more information please refer to Interface Grouping of this manual. IP address: the IP address of the router. Default is 192.168.1.254. Subnet Mask: the default Subnet mask on the router. IGMP Snooping: Enable or disable the IGMP Snooping function. Without IGMP snooping, multicast traffic is treated in the same manner as broadcast traffic - that is, it is forwarded to all ports. With IGMP snooping, multicast traffic of a group is only forwarded to ports that have members of that group.” When enabled, you will see two modes: L Standard Mode: In standard mode, multicast traffic will flood to all bridge ports when no client subscribes to a multicast group. L Blocking Mode: In blocking mode, the multicast data will be blocked when there are no client subscribes to a multicast group, it won’t flood to the bridge ports.

73 DHCP Server You can disable or enable the DHCP (Dynamic Host Configuration Protocol) server or enable the router’s DHCP relay functions. The DHCP protocol allows your router to dynamically assign IP addresses to PCs on your network if they are configured to obtain IP addresses automatically. L Disable Disable the DHCP Server function. L Enable Enable the DHCP function, enter the information wanted. Here as default. Start IP Address: the start IP address of the range the DHCP Server used to assign to the Clients. End IP Address: the end IP address f the range the DHCP Server used to assign to the Clients. Leased Time: the leased time for each DHCP Client. Maximum Leased Time(hour): the Maximum Leased Time(hour). L DHCP Server Relay If you check DHCP Relay and then you must enter the IP address of the DHCP server which assigns an IP address back to the DHCP client in the LAN. Use this function only if advised to do so by your network administrator or ISP.

74 Static IP List The specified IP will be assigned to the corresponding MAC Address listed in the following table when DHCP Server assign IP Addresses to Clients. Press Add to the Static IP List. Enter the MAC Address, IP Address and Host Name, then click Apply to confirm your settings. IP Alias This function allows the creation of multiple virtual IP interfaces on this router. It helps to connect two or more local networks to the ISP or remote node. IP Alias: check whether to enable this function. IP Address: Specify an IP address on this virtual interface. Netmask: Specify a subnet mask on this virtual interface. Click Apply to apply your settings.

75 IPv6 Autoconfig The IPv6 address composes of two parts, thus, the prefix and the interface ID. There are two ways to dynamically configure IPv6 address on hosts. One is statefull configuration, for example using DHCPv6 (which resembles its counterpart DHCP in IPv4.) In the stateful autoconfiguration model, hosts obtain interface addresses and/or configuration information and parameters from a DHCPv6 server. The Server maintains a database that keeps track of which addresses have been assigned to which hosts. The second way is stateless configuration. Stateless auto-configuration requires no manual configuration of hosts, minimal (if any) configuration of routers, and no additional servers. The stateless mechanism allows a host to generate its own addresses using a combination of locally available information (MAC address) and information (prefix) advertised by routers. Routers advertise prefixes that identify the subnet(s) associated with a link, while hosts generate an "interface identifier" that uniquely identifies an interface on a subnet. An address is formed by combining the two. When using stateless configuration, you needn’t configure anything on the client. Static LAN IPv6 Address Configuration Interface Address / Prefix Length: enter the static LAN IPv6 address. IPv6 LAN application DHCPv6 Server: check whether to enable DHCPv6 server. DHCPv6 Server Type: select Stateless or Stateful. When DHCPv6 is enabled, this parameter is available. Stateless: if selected, the PCs in LAN are configured through RA mode, thus, the PCs in LAN are configured through RA mode, to obtain the prefix message and generate an address using a combination of locally available information (MAC address) and information (prefix) advertised by routers, but they can obtain such information like DNS from DHCPv6 Server. Stateful: if selected, the PCs in LAN will be configured like in IPv4 mode, thus obtain addresses and DNS information

76 from DHCPv6 server. Start interface ID: enter the start interface ID. The IPv6 address composed of two parts, thus, the prefix and the interface ID. Interface is like the Host ID compared to IPv4. End interface ID: enter the end interface ID. Note: Interface ID does NOT support ZERO COMPRESSION "::". Please enter the complete information. For example: Please enter "0:0:0:2" instead of "::2". Leased Time (hour): the leased time, similar to leased time in DHCPv4, is a time limit assigned to clients, when expires, the assigned ID will be recycled and reassigned. Issue Router Advertisement: check whether to enable issue Router Advertisement feature. It is to send Router Advertisement messages periodically. MLD snooping: similar to IGMP snooping, listens in on the MLD conversation between hosts and routers by processing MLD packets sent in a multicast network, and it analyzes all MLD packets between hosts and the connected multicast routers in the network. Without MLD snooping, multicast traffic is treated in the same manner as broadcast traffic - that is, it is forwarded to all ports. With MLD snooping, multicast traffic of a group is only forwarded to ports that have members of that group. L Standard Mode: In standard mode, multicast traffic will flood to all bridge ports when no client subscribes to a multicast group. L Blocking Mode: In blocking mode, the multicast data will be blocked when there is no client subscribes to a multicast group, it won’t flood to the bridge ports. Stateless and Stateful IPv6 address Configuration Stateless: two methods can be adopted. L With DHCPv6 disabled, but Issue Router Advertisement Enabled With this method, the PCs in LAN are configured through RA mode, thus, the PCs in LAN are configured through RA mode, to obtain the prefix message and generate an address using a combination of locally available information (MAC address) and information (prefix) advertised by routers. L With both DHCPv6 and Issue Router Advertisement Enabled With this method, the PCs’ addresses in LAN are configured like above method, but they can obtain such information like DNS from DHCPv6 Server.

77 Stateful: two methods can be adopted. L With only DHCPv6 enabled With this method, the PCs’ addresses are configured the same as in IPv4, that is addresses are assigned by DHCPv6 server. L With both DHCPv6 and Issue Router Advertisement Enabled With this method, the PCs’ addresses are configured the same like above, and the address information in RA packets will be neglected.

78 NAT NAT (Network Address Translation) feature translates a private IP to a public IP, allowing multiple users to access the Internet through a single IP account, sharing the single IP address. It is a natural firewall for the private network. Virtual Servers In TCP/IP and UDP networks a port is a 16-bit number used to identify which application program (usually a server) incoming connections should be delivered to. Some ports have numbers that are pre-assigned to them by the IANA (the Internet Assigned Numbers Authority), and these are referred to as “well-known ports”. Servers follow the well-known port assignments so clients can locate them. If you wish to run a server on your network that can be accessed from the WAN (i.e. from other machines on the Internet that are outside your local network), or any application that can accept incoming connections (e.g. Peer-to-peer/P2P software such as instant messaging applications and P2P file-sharing applications) and are using NAT (Network Address Translation), then you will usually need to configure your router to forward these incoming connection attempts using specific ports to the PC on your network running the application. You will also need to use port forwarding if you want to host an online game server. The reason for this is that when using NAT, your publicly accessible IP address will be used by and point to your router, which then needs to deliver all traffic to the private IP addresses used by your PCs. Please see the WAN configuration section of this manual for more information on NAT. The device can be configured as a virtual server so that remote users accessing services such as Web or FTP services via the public (WAN) IP address can be automatically redirected to local servers in the LAN network. Depending on the requested service (TCP/UDP port number), the device redirects the external service request to the appropriate server within the LAN network. This part is only available when NAT is enabled. It is virtual server listing table as you see, Click Add to configure.

79 The following configuration page will appear to let you configure. Interface: select from the drop-down menu the interface you want the virtual server(s) applies to. Server Name: select the server name from the drop-down menu. Custom Service: it is a kind of service to let users customize the service they want. Enter the user-defined service name here. It is a parameter only available when users select Custom Service in the above parameter. Server IP Address: Enter your server IP Address here. External Port L Start: Enter a port number as the external starting number for the range you want to give access to internal network. L End: Enter a port number as the external ending number for the range you want to give access to internal network. Internal Port L Start: Enter a port number as the internal staring number. L End: Here it will generate automatically according to the End port number of External port and can’t be modified. Protocol: select the protocol this service used: TCP/UDP, TCP, UDP.

80 Set up 1. Select a Server Name from the drop-down menu, then the port will automatically appear, modify some as you like, or you can just leave it as default. Remember to enter your server IP Address. 2. Press Apply to conform, and the items will be list in the Virtual Servers Setup table.

81 Remove If you don’t need a specified Server, you can remove it. Check the check box beside the item you want to remove, then press Remove, it will be OK. ALG The ALG Controls enable or disable protocols over application layer.

82 DMZ Host The DMZ Host is a local computer exposed to the Internet. When setting a particular internal IP address as the DMZ Host, all incoming packets will be checked by the Firewall and NAT algorithms then passed to the DMZ host, when a packet received does not use a port number used by any other Virtual Server entries. DMZ Host IP Address: Enter the IP Address of a host you want it to be a DMZ host. Using port mapping does have security implications, since outside users are able to connect to PCs on your network. For this reason you are advised to use specific Virtual Server entries just for the ports your application requires instead of simply using DMZ or creating a Virtual Server entry for “All” protocols, as doing so results in all connection attempts to your public IP address accessing the specified PC. If you have disabled the NAT option in the WAN-ISP section, the Virtual Server function will hence be invalid. If the DHCP server option is enabled, you have to be very careful in assigning the IP addresses of the virtual servers in order to avoid conflicts. The easiest way of configuring Virtual Servers is to manually assign static IP address to each virtual server PC, with an address that does not fall into the range of IP addresses that are to be issued by the DHCP server. You can configure the virtual server IP address manually, but it must still be in the same subnet as the router. Attention
