(802.11g) ADSL2+ (VPN) Firewall Router Chapter 1: Introduction 3Chapter 1: Introduction Introduction to your Router Welcome to the (802.11g) ADSL2+ (VPN) Firewall Router. The router is an “all-in-one” ADSL router, combining an ADSL modem, ADSL router and Ethernet network switch functionalities, providing everything you need to get the machines on your network connected to the Internet over your ADSL broadband connection. With features such as an ADSL Quick-Start wizard and DHCP Server, you can be online in no time at all and with a minimum of fuss and configuration, catering for first-time users to the guru requiring advanced features and control over their Internet connection and network. Features Express Internet Access The router complies with ADSL worldwide standards. It supports downstream rate up to 12/24 Mbps with ADSL2/2+, 8Mbps with ADSL. Users enjoy not only high-speed ADSL services but also broadband multimedia applications such as interactive gaming, video streaming and real-time audio much easier and faster than ever. It is compliant with Multi-Mode standard (ANSI T1.413, Issue 2; G.dmt (ITU G.992.1); G.lite (ITU G.992.2); G.hs (ITU G994.1); G.dmt.bis (ITU G.992.3); G.dmt.bis.plus (ITU G.992.5)). Virtual Private Network (VPN) It allows user to make a tunnel with a remote site directly to secure the data transmission among the connection. User can use embedded PPTP and L2TP client/server, IKE and IPSec which are supported by this router to make a VPN connection or users can run the PPTP client in PC and the router already provides IPSec and PPTP pass through function to establish a VPN connection if the user likes to run the PPTP client in his local computer. 802.11g Wireless AP with WPA Support (Wireless Router only)With integrated 802.11g Wireless Access Point in the router, the device offers a quick and easy access among wired network, wireless network and broadband connection (ADSL) with single device simplicity, and as a result, mobility to the users. In addition to 54 Mbps 802.11g data rate, it also interoperates backward with existing 802.11b equipment. The Wireless Protected Access (WPA1 and WPA2) and Wireless Encryption Protocol (WEP) supported features enhance the security level of data protection and access control via Wireless LAN. Fast Ethernet SwitchA 4-port 10/100Mbps fast Ethernet switch is built in with automatic switching between MDI and MDI-X for 10Base-T and 100Base-TX ports. An Ethernet straight or crossover cable can be used directly for auto detection. Multi-Protocol to Establish a ConnectionIt supports PPPoA (RFC 2364 - PPP over ATM Adaptation Layer 5), RFC 1483 encapsulation over ATM (bridged or routed), PPP over Ethernet (RFC 2516), and IPoA (RFC1577) to establish a connection with the ISP. The product also supports VC-based and LLC-based multiplexing. Quick Installation Wizard It supports a WEB GUI page to install this device quickly. With this wizard, end users can enter the information easily which they get from their ISP, then surf the Internet immediately. Universal Plug and Play (UPnP) and UPnP NAT TraversalThis protocol is used to enable simple and robust connectivity among stand-alone devices and PCs from many different vendors. It makes network simple and affordable for users. UPnP architecture
(802.11g) ADSL2+ (VPN) Firewall Router Chapter 1: Introduction 4leverages TCP/IP and the Web to enable seamless proximity networking in addition to control and data transfer among networked devices. With this feature enabled, users can now connect to Net meeting or MSN Messenger seamlessly. Network Address Translation (NAT)Allows multi-users to access outside resources such as the Internet simultaneously with one IP address/one Internet access account. Many application layer gateway (ALG) are supported such as web browser, ICQ, FTP, Telnet, E-mail, News, Net2phone, Ping, NetMeeting, IP phone and others. SOHO Firewall Security with DoS and SPIAlong with the built-in NAT natural firewall feature, the router also provides advanced hacker pattern-filtering protection. It can automatically detect and block Denial of Service (DoS) attacks. The router is built with Stateful Packet Inspection (SPI) to determine if a data packet is allowed through the firewall to the private LAN. Domain Name System (DNS) RelayIt provides an easy way to map the domain name (a friendly name for users such as www.yahoo.com) and IP address. When a local machine sets its DNS server with this router’s IP address, every DNS conversion request packet from the PC to this router will be forwarded to the real DNS in the outside network. Dynamic Domain Name System (DDNS)The Dynamic DNS service allows you to alias a dynamic IP address to a static hostname. This dynamic IP address is the WAN IP address. For example, to use the service, you must first apply for an account from a DDNS service like http://www.dyndns.org/. More than 5 DDNS servers are supported. Quality of Service (QoS)QoS gives you full control over which types of outgoing data traffic should be given priority by the router, ensuring important data like gaming packets, customer information, or management information move through the router ay lightning speed, even under heavy load. The QoS features are configurable by source IP address, destination IP address, protocol, and port. You can throttle the speed at which different types of outgoing data pass through the router, to ensure P2P users don’t saturate upload bandwidth, or office browsing doesn’t bring client web serving to a halt. In addition, or alternatively, you can simply change the priority of different types of upload data and let the router sort out the actual speeds. Virtual Server (“port forwarding”)Users can specify some services to be visible from outside users. The router can detect incoming service requests and forward either a single port or a range of ports to the specific local computer to handle it. For example, a user can assign a PC in the LAN acting as a WEB server inside and expose it to the outside network. Outside users can browse inside web servers directly while it is protected by NAT. A DMZ host setting is also provided to a local computer exposed to the outside network, Internet. Rich Packet FilteringNot only filters the packet based on IP address, but also based on Port numbers. It will filter packets from and to the Internet, and also provides a higher level of security control. Dynamic Host Configuration Protocol (DHCP) Client and ServerIn the WAN site, the DHCP client can get an IP address from the Internet Service Provider (ISP) automatically. In the LAN site, the DHCP server can allocate a range of client IP addresses and distribute them including IP address, subnet mask as well as DNS IP address to local computers. It provides an easy way to manage the local IP network. Static and RIP1/2 Routing It has routing capability and supports easy static routing table or RIP1/2 routing protocol.

Make sure that all connected devices are turned on. On the front of the product is a bank of LEDs. Verify that the LAN Link and ADSL line LEDs are lit. If they are not, verify that you are using the proper cables. 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.
(802.11g) ADSL2+ (VPN) Firewall Router Chapter 3: Basic Installation 10Any TCP/IP capable workstation can be used to communicate with or through the router. To configure other types of workstations, please consult the manufacturer’s documentation. Chapter 3: Basic Installation The router can be configured with your web browser. A web browser is included as a standard application in the following operating systems: Linux, Mac OS, Windows 98/NT/2000/XP/Me, etc. The product provides an easy and user-friendly interface for configuration. Please check your PC’s 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 with the router, either through an external repeater hub to the router or directly connecting with PCs. However, to be sure PCs have an Ethernet interface installed properly prior to connecting to 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’s web interface it may also be advisable to uninstall any kind of software firewall on your PCs, as they can cause problems accessing the 192.168.1.254 IP address of the router.

(802.11g) ADSL2+ (VPN) Firewall Router Chapter 4: Configuration 38WPSWPS feature is follow Wi-Fi Alliance WPS standard and it easily set up security-enabled Wi-Fi networks in the home and small office environment. It is reduced by half the user steps to configure a network and supports two methods that are familiar to most consumers to configure a network and enable security. Port Setting This section allows you to configure the settings for the router’s Ethernet ports to solve some of the compatibility problems that may be encountered while connecting to the Internet, as well allowing users to tweak the performance of their network. Port # Connection Type: There are Six options to choose from: Auto, disable, 10M half-duplex, 10M full-duplex, 100M half-duplex, 100M full-duplex and Disable. Sometimes, there are Ethernet compatibility problems with legacy Ethernet devices, and you can configure different types to solve compatibility issues. The default is Auto, which users should keep unless there are specific problems with PCs not being able to access your LAN. IPv4 TOS priority Control (Advanced users): TOS, Type of Services, is the 2nd octet of an IP packet. Bits 6-7 of this octet are reserved and bit 0-5 are used to specify the priority of the packet. This feature uses bits 0-5 to classify the packet’s priority. If the packet is high priority, it will flow first and will not be constrained by the Rate Limit. Therefore, when this feature is enabled, the router’s Ethernet switch will check the 2nd octet of each IP packet. If the value in the TOS field matches the checked values in the table (0 to 63), this packet will be treated as high priority.
(802.11g) ADSL2+ (VPN) Firewall Router Chapter 4: Configuration 39DHCP 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. To disable the router’s DHCP Server, check Disabled and click Next, then click Apply. When the DHCP Server is disabled you will need to manually assign a fixed IP address to each PCs on your network, and set the default gateway for each PCs to the IP address of the router (by default this is 192.168.1.254). To configure the router’s DHCP Server, check DHCP Server and click Next. You can then configure parameters of the DHCP Server including the IP pool (starting IP address and ending IP address to be allocated to PCs on your network), lease time for each assigned IP address (the period of time the IP address assigned will be valid), DNS IP address and the gateway IP address. These details are sent to the DHCP client (i.e. your PC) when it requests an IP address from the DHCP server. Click Apply to enable this function. If you check “Use Router as a DNS Server”, the ADSL Router will perform the domain name lookup, find the IP address from the outside network automatically and forward it back to the requesting PC in the LAN (your Local Area Network). If you check DHCP Relay Agent and click Next, then you will have to enter the IP address of the DHCP server which will assign 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. Click Apply to enable this function.

Improper operation could damage the router. Firmware Upgrade Your router’s “firmware” is the software that allows it to operate and provides all its functionality. Think of your router as a dedicated computer, and the firmware as the software it runs. Over time this software may be improved and revised, and your router allows you to upgrade the software it runs to take advantage of these changes. Clicking on Browse will allow you to select the new firmware image file you have downloaded to your PC. Once the correct file is selected, click Upgrade to update the firmware in your router.
(802.11g) ADSL2+ (VPN) Firewall Router Chapter 4: Configuration 52Backup / Restore These functions allow you to save and backup your router’s current settings to a file on your PC, or to restore a previously saved backup. This is useful if you wish to experiment with different settings, knowing that you have a backup handy in the case of any mistakes. It is advisable to backup your router’s settings before making any significant changes to your router’s configuration. Press Backup to select where on your local PC to save the settings file. You may also change the name of the file when saving if you wish to keep multiple backups. Press Browse to select a file from your PC to restore. You should only restore settings files that have been generated by the Backup function, and that were created when using the current version of the router’s firmware. Settings files saved to your PC should not be manually edited in any way.After selecting the settings file you wish to use, pressing Restore will load those settings into the router.

Firewall and Access Control Your router includes a full SPI (Stateful Packet Inspection) firewall for controlling Internet access from your LAN, as well as helping to prevent attacks from hackers. Besides, when using NAT, the router acts as a “natural” Internet firewall, as all PCs on your LAN will use private IP addresses that cannot be directly accessed from the Internet. 1 23412
(802.11g) ADSL2+ (VPN) Firewall Router Chapter 4: Configuration 56When using Virtual Servers your PCs will be exposed to the degree specified in your Virtual Server settings provided the ports specified are opened in your firewall packet filter settings. Firewall: Prevents access from outside your network. The router provides three levels of security support:NAT natural firewall: This masks LAN users’ IP addresses which is invisible to outside users on the Internet, making it much more difficult for a hacker to target a machine on your network. This natural firewall is on when NAT function is enabled. Firewall Security and Policy (General Settings): Inbound direction of Packet Filter rules to prevent unauthorized computers or applications accessing your local network from the Internet. Intrusion Detection: Enable Intrusion Detection to detect, prevent and log malicious attacks. Access Control: Prevents access from PCs on your local network: Firewall Security and Policy (General Settings): Outbound direction of Packet Filter rules to prevent unauthorized computers or applications accessing the Internet. URL Filter: To block PCs on your local network from unwanted websites.Here are the items within the Firewall section: General Settings, Packet Filter, Intrusion Detection, URL Filter, IM/P2P Blocking and Firewall Log. General Settings You can choose not to enable Firewall and still able to access to URL Filter and IM/P2P Blocking or enable the Firewall using preset filter rules and modify the port filter rules as required. The Packet Filter is used to filter packets based-on Applications (Port) or IP addresses. There are four options when you enable the Firewall, they are: ~All blocked/User-defined: no pre-defined port or address filter rules by default, meaning that all inbound (Internet to LAN) and outbound (LAN to Internet) packets will be blocked. Users have to
(802.11g) ADSL2+ (VPN) Firewall Router Chapter 4: Configuration 57add their own filter rules for further access to the Internet. ~High/Medium/Low security level: the predefined port filter rules for High, Medium and Low security are displayed in Port Filters of Packet Filter. Select either High, Medium or Low security level to enable the Firewall. The only difference between these three security levels is the preset port filter rules in the Packet Filter. Firewall functionality is the same for all levels; it is only the list of preset port filters that changes between each setting. For more detailed on level of preset port filter information, refer to Table 1: Predefined Port Filter.If you choose of the preset security levels and add custom filters, this level of filter rules will be saved even and do not need to re-configure the rules again if you disable or switch to other firewall level. The “Block WAN Request” is a stand-alone function and not relate to whether security enable or disable. Mostly it is for preventing any scan tools from WAN site by hacker. (Changed the format only.)Any remote user who is attempting to perform this action may result in blocking all the accesses to configure and manage of the device from the Internet.
(802.11g) ADSL2+ (VPN) Firewall Router Chapter 4: Configuration 58Packet Filter This function is only available when the Firewall is enabled and one of these four security levels is chosen (All blocked, High, Medium and Low). The preset port filter rules in the Packet Filter must modify accordingly to the level of Firewall, which is selected. See Table1: Predefined Port Filter for more detail information.
(802.11g) ADSL2+ (VPN) Firewall Router Chapter 4: Configuration 59Example: Predefined Port Filters Rules The predefined port filter rules for High, Medium and Low security levels are listed.

(802.11g) ADSL2+ (VPN) Firewall Router Chapter 4: Configuration 65Intrusion Detection The router’s Intrusion Detection System (IDS) is used to detect hacker attacks and intrusion attempts from the Internet. If the IDS function of the firewall is enabled, inbound packets are filtered and blocked depending on whether they are detected as possible hacker attacks, intrusion attempts or other connections that the router determines to be suspicious. Blacklist: If the router detects a possible attack, the source IP or destination IP address will be added to the Blacklist. Any further attempts using this IP address will be blocked for the time period specified as the Block Duration. The default setting for this function is false (disabled). Some attack types are denied immediately without using the Blacklist function, such as Land attack and Echo/CharGen scan.Intrusion Detection: If enabled, IDS will block Smurf attack attempts. Default is false. Block Duration:~ Victim Protection Block Duration: This is the duration for blocking Smurf attacks. Default value is 600 seconds.~ Scan Attack Block Duration: This is the duration for blocking hosts that attempt a possible Scan attack. Scan attack types include X’mas scan, IMAP SYN/FIN scan and similar attempts.
(802.11g) ADSL2+ (VPN) Firewall Router Chapter 4: Configuration 66Default value is 86400 seconds.~ DoS Attack Block Duration: This is the duration for blocking hosts that attempt a possible Denial of Service (DoS) attack. Possible DoS attacks this attempts to block include Ascend Kill and WinNuke. Default value is 1800 seconds.Max TCP Open Handshaking Count: This is a threshold value to decide whether a SYN Flood attempt is occurring or not. Default value is 100 TCP SYN per seconds. Max PING Count: This is a threshold value to decide whether an ICMP Echo Storm is occurring or not.Default value is 15 ICMP Echo Requests (PING) per second. Max ICMP Count: This is a threshold to decide whether an ICMP flood is occurring or not. Default value is 100 ICMP packets per seconds except ICMP Echo Requests (PING). For SYN Flood,ICMP Echo Storm and ICMP flood, IDS will just warn the user in the Event Log. It cannot protect against such attacks.

(802.11g) ADSL2+ (VPN) Firewall Router Chapter 4: Configuration 68URL Filter URL (Uniform Resource Locator – e.g. an address in the form of http://www.abcde.com or http://www.example.com) filter rules allow you to prevent users on your network from accessing particular websites by their URL. There are no pre-defined URL filter rules; you can add filter rules to meet your requirements. Enable/Disable: To enable or disable URL Filter feature. Block Mode: A list of the modes that you can choose to check the URL filter rules. The default is set to Always On.~ Disabled: No action will be performed by the Block Mode. ~ Always On: Action is enabled. URL filter rules will be monitoring and checking at all hours of the day. ~ TimeSlot1 ~ TimeSlot16: It is self-defined time period. You may specify the time period to check the URL filter rules, i.e. during working hours. For setup and detail, refer to Time Schedule section. Keywords Filtering: Allows blocking by specific keywords within a particular URL rather than having to specify a complete URL (e.g. to block any image called “advertisement.gif”). When enabled, your specified keywords list will be checked to see if any keywords are present in URLs accessed to determine if the connection attempt should be blocked. Please note that the URL filter blocks web browser (HTTP) connection attempts using port 80 only. For example, if the URL is http://www.abc.com/abcde.html, it will be dropped as the keyword “abcde” occurs in the URL.
(802.11g) ADSL2+ (VPN) Firewall Router Chapter 4: Configuration 69Domains Filtering: This function checks the whole URL not the IP address, in URLs accessed against your list of domains to block or allow. If it is matched, the URL request will be sent (Trusted) or dropped (Forbidden). For this function to be activated, both check-boxes must be checked. Here is the checking procedure: 1. Check the domain in the URL to determine if it is in the trusted list. If yes, the connection attempt is sent to the remote web server. 2. If not, check if it is listed in the forbidden list. If yes, then the connection attempt will be dropped.3. If the packet does not match either of the above two items, it is sent to the remote web server. 4. Please be note that the completed URL, “www” + domain name shall be specified. For example to block traffic to www.google.com.au, enter “www.google” or “www.google.com”In the example below, the URL request for www.abc.com will be sent to the remote web server because it is listed in the trusted list, whilst the URL request for www.google or www.google.com will be dropped, because www.google is in the forbidden list. Example: Andy wishes to disable all WEB traffic except for ones listed in the trusted domain, which would prevent Bobby from accessing other web sites. Andy selects both functions in the Domain Filtering and thinks that it will stop Bobby. But Bobby knows this function, Domain Filtering, ONLY disables all WEB traffic except for Trusted Domain, BUT not its IP address. If this is the situation, Block surfing by IP address function can be handy and helpful to Andy. Now, Andy can prevent Bobby from accessing other sites. Restrict URL Features: This function enhances the restriction to your URL rules. ~Block Java Applet: This function can block Web content that includes the Java Applet. It is to prevent someone who wants to damage your system via standard HTTP protocol. ~Block surfing by IP address: Preventing someone who uses the IP address as URL for skipping Domains Filtering function. Activates only and if Domain Filtering enabled.

IKE (Internet key Exchange) Mode: Select IKE mode to Main mode or Aggressive mode. This IKE provides secured key generation and key management. Hash Function: It is a Message Digest algorithm which coverts any length of a message into a unique set of bits. It is widely used MD5 (Message Digest) and SHA-1 (Secure Hash Algorithm) algorithms. SHA1 is more resistant to brute-force attacks than MD5, however it is slower. ~ MD5: A one-way hashing algorithm that produces a 128íbit hash. ~ SHA1: A one-way hashing algorithm that produces a 160íbit hashEncryption: Select the encryption method from the pull-down menu. There are several options, DES,3DES and AES (128, 192 and 256). 3DES and AES are more powerful but increase latency.~ DES: Stands for Data Encryption Standard, it uses 56 bits as an encryption method. ~ 3DES: Stands for Triple Data Encryption Standard, it uses 168 (56*3) bits as an encryption method.~ AES: Stands for Advanced Encryption Standards, you can use 128, 192 or 256 bits as
(802.11g) ADSL2+ (VPN) Firewall Router Chapter 4: Configuration 83encryption method. Diffie-Hellman Group: It is a public-key cryptography protocol that allows two parties to establish a shared secret over an unsecured communication channel (i.e. over the Internet). There are three modes, MODP 768-bit, MODP 1024-bit and MODP 1536-bit. MODP stands for Modular Exponentiation Groups. IPSec Proposal: Select the IPSec security method. There are two methods of checking the authentication information, AH (authentication header) and ESP (Encapsulating Security Payload). Use ESP for greater security so that data will be encrypted and authenticated. Using AH data will be authenticated but not encrypted. Authentication: Authentication establishes the integrity of the datagram and ensures it is not tampered with in transmit. There are three options, Message Digest 5 (MD5), Secure Hash Algorithm (SHA1) or NONE. SHA1 is more resistant to brute-force attacks than MD5, however it is slower. ~ MD5: A one-way hashing algorithm that produces a 128íbit hash. ~ SHA1: A one-way hashing algorithm that produces a 160íbit hash.Encryption: Select the encryption method from the pull-down menu.

NULL means it is a tunnel only with no encryption. 3DES and AES are more powerful but increase latency. ~ DES: Stands for Data Encryption Standard, it uses 56 bits as an encryption method. ~ 3DES: Stands for Triple Data Encryption Standard, it uses 168 (56*3) bits as an encryption method.~ AES: Stands for Advanced Encryption Standards, you can use 128, 192 or 256 bits as encryption method. Perfect Forward Secrecy: Choose whether to enable PFS using Diffie-Hellman public-key cryptography to change encryption keys during the second phase of VPN negotiation. This function will provide better security, but extends the VPN negotiation time. Diffie-Hellman is a public-key cryptography protocol that allows two parties to establish a shared secret over an unsecured communication channel (i.e. over the Internet). There are three modes, MODP 768-bit, MODP 1024-bit and MODP 1536-bit. MODP stands for Modular Exponentiation Groups. Pre-shared Key: This is for the Internet Key Exchange (IKE) protocol, a string from 4 to 128 characters. Both sides should use the same key. IKE is used to establish a shared security policy and authenticated keys for services (such as IPSec) that require a key. Before any IPSec traffic can be passed, each router must be able to verify the identity of its peer. This can be done by manually entering the pre-shared key into both sides (router or hosts). Local ID: ~ Content: Input ID’s information, like domain name www.ipsectest.com.Remote ID: ~ Identifier: Input remote ID’s information, like domain name www.ipsectest.com.SA Lifetime: Specify the number of minutes that a Security Association (SA) will stay active before new encryption and authentication key will be exchanged. There are two kinds of SAs, IKE and IPSec. IKE negotiates and establishes SA on behalf of IPSec, an IKE SA is used by IKE. ~ Phase 1 (IKE): To issue an initial connection request for a new VPN tunnel. The range can be from 5 to 15,000 minutes, and the default is 480 minutes. ~ Phase 2 (IPSec): To negotiate and establish secure authentication. The range can be from 5 to 15,000 minutes, and the default is 60 minutes.A short SA time increases security by forcing the two parties to update the keys. However, every time the VPN tunnel re-negotiates, access through the tunnel will be temporarily disconnected. PING for Keep Alive: ~None: The default setting is None. To this mode, it will not detect the remote IPSec peer has
(802.11g) ADSL2+ (VPN) Firewall Router Chapter 4: Configuration 84been lost or not. It only follows the policy of Disconnection time after no traffic, which the remote IPSec will be disconnected after the time you set in this function.~PING: This mode will detect the remote IPSec peer has lost or not by pinging specify IP address.~DPD: Dead peer detection (DPD) is a keeping alive mechanism that enables the router to be detected lively when the connection between the router and a remote IPSec peer has lost. Please be noted, it must be enabled on the both sites.PING to the IP: It is able to IP Ping the remote PC with the specified IP address and alert when the connection fails. Once alter message is received, Router will drop this tunnel connection. Re-establish of this connection is required. Default setting is 0.0.0.0 which disables the function. Interval: This sets the time interval between Pings to the IP function to monitor the connection status. Default interval setting is 10 seconds. Time interval can be set from 0 to 3600 second, 0 second disables the function. Ping to the IP Interval (sec) Ping to the IP Action 0.0.0.0 0 No 0.0.0.0 2000 Noxxx.xxx.xxx.xxx (A valid IP Address) 0 No xxx.xxx.xxx.xxx(A valid IP Address) 2000 Yes, activate it in every 2000 second. Disconnection Time after no traffic: It is the NO Response time clock. When no traffic stage time is beyond the Disconnection time set, Router will automatically halt the tunnel connection and re-establish it base on the Reconnection Time set. 180 seconds is minimum time interval for this function. Reconnection Time: It is the reconnecting time interval after NO TRAFFIC is initiated. 3 minutes isminimum time interval for this function. Click Edit/Delete to save your changes.

(802.11g) ADSL2+ (VPN) Firewall Router Chapter 4: Configuration 111Virtual Server (known as Port Forwarding) 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
(802.11g) ADSL2+ (VPN) Firewall Router Chapter 4: Configuration 112Add Virtual Server Because NAT can act as a “natural” Internet firewall, your router protects your network from being accessed by outside users when using NAT, as all incoming connection attempts will point to your router unless you specifically create Virtual Server entries to forward those ports to a PC on your network. When your router needs to allow outside users to access internal servers, e.g. a web server, FTP server, Email server or game server, the router can act as a “virtual server”. You can set up a local server with a specific port number for the service to use, e.g. web/HTTP (port 80), FTP (port 21), Telnet (port 23), SMTP (port 25), or POP3 (port 110), When an incoming access request to the router for a specified port is received, it will be forwarded to the corresponding internal server. Application: Users-define description to identify this entry or click drop-down menu to select existing predefined rules. : 20 predefined rules are available. Application, Protocol and External/Redirect Ports will be filled after the selection. Protocol: It is the supported protocol for the virtual server. In addition to specifying the port number to be used, you will also need to specify the protocol used. The protocol used is determined by the particular application. Most applications will use TCP or UDP. Time Schedule: User-defined time period to enable your virtual server. You may specify a time schedule or Always on for the usage of this Virtual Server Entry. For setup and detail, refer to Time Schedule section External Port: The Port number on the Remote/WAN side used when accessing the virtual server. Redirect Port: The Port number used by the Local server in the LAN network. Internal IP Address: The private IP in the LAN network, which will be providing the virtual server application. List all existing PCs connecting to the network. You may assign a PC with IP address and MAC from this list.
(802.11g) ADSL2+ (VPN) Firewall Router Chapter 4: Configuration 113Example:If you like to remote accessing your Router through the Web/HTTP at all time, you would need to enable port number 80 (Web/HTTP) and map to Router’s IP Address. Then all incoming HTTP requests from you (Remote side) will be forwarded to the Router with IP address of 192.168.1.254. Since port number 80 has already been predefined, next to the Application click Helper. A list of predefined rules window will pop and select HTTP_Sever.

Edit/Delete: Click it to edit or delete this virtual server application. 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. AttentionUsing port forwarding does have security implications, as outside users will be 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 using DMZ. As doing so will result in all connections from the WAN attempt to access to your public IP of the DMZ PC specified.
(802.11g) ADSL2+ (VPN) Firewall Router Chapter 4: Configuration 114Edit DMZ HostThe 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.Cautious: This Local computer exposing to the Internet may face varies of security risks. Go to ConfigurationÆVirtual ServerÆEdit DMZ Host~ Enabled: It activates your DMZ function. ~ Disabled: As set in default setting, it disables the DMZ function. Internal IP Address: Give a static IP address to the DMZ Host when Enabled radio button is checked. Be aware that this IP will be exposed to the WAN/Internet.

(802.11g) ADSL2+ (VPN) Firewall Router Chapter 4: Configuration 121Dynamic DNS The Dynamic DNS function allows you to alias a dynamic IP address to a static hostname, allowing users whose ISP does not assign them a static IP address to use a domain name. This is especially useful for hosting servers via your ADSL connection, so that anyone wishing to connect to you may use your domain name, rather than having to use your dynamic IP address, which changes from time to time. This dynamic IP address is the WAN IP address of the router, which is assigned to you by your ISP. You will first need to register and establish an account with the Dynamic DNS provider using their website, for example http://www.dyndns.org/ There are more than 5 DDNS services supported.Dynamic DNS: ~ Disable: Check to disable the Dynamic DNS function.~ Enable: Check to enable the Dynamic DNS function. The following fields will be activated and required:Dynamic DNS Server: Select the DDNS service you have established an account with.Domain Name, Username and Password: Enter your registered domain name and your username and password for this service.Period: Set the time period between updates, for the Router to exchange information with the DDNS server. In addition to updating periodically as per your settings, the router will perform an update when your dynamic IP address changes.
(802.11g) ADSL2+ (VPN) Firewall Router Chapter 4: Configuration 122Check Email This function allows you to have the router check your POP3 mailbox for new Email messages. The Mail LED on your router will light when it detects new messages waiting for download. You may also view the status of this function using the Status – Email Checking section of the web interface, which also provides details on the number of new messages waiting. See the Status section of this manual for more information.Check Email: ~ Disable: Check to disable the router’s Email checking function.~ Enable: Check to enable the routers Email checking function. The following fields will be activated and required: Account Name: Enter the name (login) of the POP3 account you wish to check. Normally, it is the text in your email address before the "@" symbol. If you have trouble with it, please contact your ISP. Password: Enter the account’s password. POP3 Mail Server: Enter your (POP) mail server name. You Internet Service Provider (ISP) or network administrator will be able to supply you with this.Period: Enter the value in minutes between periodic mail checks. Dial-out for checking emails: When the function is enabled, your ADSL router will connect to your ISP automatically to check emails if your Internet connection dropped. Please be careful when using this feature if your ADSL service is charged by time online.
(802.11g) ADSL2+ (VPN) Firewall Router Chapter 4: Configuration 123Device Management The Device Management advanced configuration settings allow you to control your router’s security options and device monitoring features. Device Host Name Host Name: Give a name for it.(The Host Name cannot be used with one word only. There are two words should be connected with a '.' at least. Example:Host Name: homegateway ==> Incorrect Host Name: home.gateway or my.home.gateway ==> Correct) Embedded Web Server ( 2 Management IP Accounts)HTTP Port: This is the port number the router’s embedded web server (for web-based configuration) will use. The default value is the standard HTTP port, 80. Users may specify an alternative if, for example, they are running a web server on a PC within their LAN. Management IP Address: You may specify an IP address allowed to logon and access the router’s web server. Setting the IP address to 0.0.0.0 will disable IP address restrictions, allowing users to login from any IP address. Expire to auto-logout: Specify a time frame for the system to auto-logout the user’s configuration session.For Example: User A changes HTTP port number to 100, specifies their own IP address of 192.168.1.55,and sets the logout time to be 100 seconds. The router will only allow User A access from the IP address 192.168.1.55 to logon to the Web GUI by typing: http://192.168.1.254:100 in their web browser. After 100 seconds, the device will automatically logout User A.
(802.11g) ADSL2+ (VPN) Firewall Router Chapter 4: Configuration 124Universal Plug and Play (UPnP)UPnP offers peer-to-peer network connectivity for PCs and other network devices, along with control and data transfer between devices. UPnP offers many advantages for users running NAT routers through UPnP NAT Traversal, and on supported systems makes tasks such as port forwarding much easier by letting the application control the required settings, removing the need for the user to control advanced configuration of their device. Both the user’s Operating System and the relevant application must support UPnP in addition to the router. Windows XP and Windows Me natively support UPnP (when the component is installed), and Windows 98 users may install the Internet Connection Sharing client from Windows XP in order to support UPnP. Windows 2000 does not support UPnP. ~ Disable: Check to disable the router’s UPnP functionality. ~ Enable: Check to enable the router’s UPnP functionality. UPnP Port: Its default setting is 2800. It is highly recommended for users to use this port value. If this value conflicts with other ports already being used you may wish to change the port. SNMP Access Control (Software on a PC within the LAN is required in order to utilize this function) – Simple Network Management Protocol. SNMP V1 and V2:Read Community: Specify a name to be identified as the Read Community, and an IP address. This community string will be checked against the string entered in the configuration file. Once the string name is matched, user obtains this IP address will be able to view the data. Write Community: Specify a name to be identified as the Write Community, and an IP address. This community string will be checked against the string entered in the configuration file. Once the string name is matched, users from this IP address will be able to view and modify the data. Trap Community: Specify a name to be identified as the Trap Community, and an IP address. This community string will be checked against the string entered in the configuration file. Once the string name is matched, users from this IP address will be sent SNMP Traps. SNMP V3: Specify a name and password for authentication. And define the access right from identified IP address. Once the authentication has succeeded, users from this IP address will be able to view and modify the data.SNMP Version: SNMPv2c and SNMPv3 SNMPv2c is the combination of the enhanced protocol features of SNMPv2 without the SNMPv2 security. The "c" comes from the fact that SNMPv2c uses the SNMPv1 community string paradigm for "security", but is widely accepted as the SNMPv2 standard. SNMPv3 is a strong authentication mechanism, authorization with fine granularity for remote monitoring. Traps supported: Cold Start, Authentication Failure.

(802.11g) ADSL2+ (VPN) Firewall Router Appendix A: Product Support and Contact Information 128Chapter 5: TroubleshootingIf the router is not functioning properly, first check this chapter for simple troubleshooting before contacting your service provider or Billion support. Problems starting up the router Problem Corrective Action None of the LEDs are on when you turn on the router. Check the connection between the adapter and the router. If the error persists, you may have a hardware problem. In this case you should contact technical support. You have forgotten your router login and/or password. Try the default login and password, refer to Chapter 3. If this fails, you can restore your router to its factory settings by holding the Reset button on the back of your router more than 6 seconds. Caution: After pressing the RESET button for more than 6 seconds, to be sure you power cycle the device again.Problems with the WAN Interface Problem Corrective Action Initialization of the PVC connection (“linesync”) failed. Ensure that the telephone cable is connected properly from the ADSL port to the wall jack. The ADSL LED on the front panel of the router should be on. Check that your VPI, VCI, encapsulation type and type of multiplexing settings are the same as those provided by your ISP. Reboot the router GE. If you still have problems, you may need to verify these settings with your ISP. Frequent loss of ADSL linesync (disconnections).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. Problems with the LAN Interface Problem Corrective Action Can’t ping any PCs on the LAN. Check the Ethernet LEDs on the front panel. The LED should be on for a port that has a PC connected. If it is off, check the cables between your router and the PC. Make sure you have uninstalled any software firewall for troubleshooting. Verify that the IP address and the subnet mask are consistent between the router and the workstations.
