84 Wireless Bridge WDS (wireless distributed system) is a wireless access point mode that enables wireless link and communication with other access points. It’s easy to install, simply define the peer’s MAC address of the connected AP. WDS takes advantage of cost saving and flexibility with no extra wireless client device required to bridge between two access points and extending an existing wired or wireless infrastructure network to create a larger network. Here you can select what role the AP server has, AP or wireless bridge (WDS). AP Mode: determines whether the gateway will act as an Access point or as a Bridge.  Access Point: the gateway communicates with both clients and bridges.  Wireless Bridge: the gateway communicates with other WDS devices only. In this mode, the gateway doesn’t communicate with client devices. If your wireless network includes repeaters that use WDS, the gateway in wireless bridge mode will also communicate with your repeaters. The gateway in wireless bridge mode will not communicate with a repeater that uses a proprietary (non-WDS) mode. Bridge Restrict: When AP Mode is set to Wireless Bridge, this determines whether the gateway will communicate with all other bridges or only specific ones:  Enable: to enable wireless bridge restriction. Only those specified in the Remote MAC Address the gateway can communicate with. Remote Bridge MAC Address: enter the remote bridge MAC addresses. Here up to 4 bridge MAC addresses are supported.  Enabled (Scan): to enable wireless bridge restriction. Only those scanned by the gateway can communicate.
85 Remote Bridge MAC Address: select the remote bridge MAC addresses.  Disable: Does not restrict the gateway communicating with bridges that have their MAC address listed, but it is still open to communicate with all bridges that are in the same network. Click Apply to apply your settings.

Ping: To ping to check the master WAN inteface’s connectivity.  Gateway: It will send ping packets to gateway of master interface and wait for response from it in every “Probe Cycle” to check the connectivity of the gateway of master interface.  Host: It will send ping packets to specific host and wait for response in every “Probe Cycle”. Slave Interface: Select a slave WAN interface as backup port. Ping: To ping to check the slave WAN inteface’s connectivity.  Gateway: It will send ping packets to gateway of slave interface and wait for response from it in every “Probe Cycle” to check the connectivity of the gateway of slave interface.  Host: It will send ping packets to specific host and wait for response in every “Probe Cycle”. Probe Cycle: Set the time duration for the Probe Cycle to determine when the router will switch to the backup connection once the main connection (main port) fails. For example, when set to 30 seconds, the probe will be conducted every 30 seconds. Connectivity Decision: Set how many times of probing failure to switch to backup port. Note: 1) The time set is for each probe cycle, but the decision to change to the backup port is determined by Probe Cycle multiplied by connection Decision amount (e.g. From the image above it will be 30 seconds multiplied by 3 consecutive fails, the router will determine failover to slave interface. 2).The failback setting follow the same decision policy as the failover. For example, according to settings above in the screenshot, the connection probe will be carried out every 30 seconds, and 3 consecutive times of probe success is found, the router will determine failback to master interface.

136 IP Tunnel An IP Tunnel is an Internet Protocol (IP) network communication channels between two networks of different protocols. It is used to transport another network protocol by encapsulation of its packets. IP Tunnels are often used to connect two disjoint IP networks that do not have a native routing path to each other, via an underlying routable protocol across an intermediate transport network, like VPN. Another prominent use of IP Tunnel is to connect islands of IPv6 installations across the IPv4 internet. IPv6inIPv4 6in4 is an Internet transition mechanism for migrating from IPv4 to IPv6. 6in4 uses tunneling to encapsulate IPv6 traffic over explicitly configured IPv4 links. The 6in4 traffic is sent over the IPv4 Internet inside IPv4 packets whose IP headers have the IP Protocol number set to 41. This protocol number is specifically designated for IPv6 capsulation. 6RD: 6RD is a mechanism to facilitate IPv6 rapid deployment across IPv4 infrastructures of internet service providers (ISPs). It is derived from 6to4, a preexisting mechanism to transporting IPv6 packets over IPv4 infrastructure network, with the significant change that it operates entirely within the enduser’s ISP network, thus avoiding the major architectural problems inherent in the original design of 6to4. Click Add button to manually add the 6in4 rules. Tunnel Name: User-defined name. Mechanism: Here only 6RD.
137 Associated WAN Interface: The applied WAN interface with the set tunnel, thus when there are packets from/to the WAN interface, the tunnel would be used to transport the packets. Associated LAN Interface: Set the linked LAN interface with the tunnel. Method: 6rd operation mechanism: manually configured or automatically configured. If manually, please fill out the following 6rd parameters. V4 Common Bit Length: Specify the length of IPv4 address carried in IPv6 prefix, for example, 0 means to carry all the 32 bits of IPv4 address while 8 carries 24 bits of the IPv4 address. 6rd Prefix with Prefix Length: Enter the 6rd prefix and prefix length you uniquely designate to 6rd by the ISP( The 6rd prefix and prefix length are to replace the standard 6to4 prefix 2002::/16 by an IPv6 prefix that belongs to the ISP-assigned.) Border Relay IPv4 Address: The IPv4 address of the border relay. The relay is used to unwrap capsulated IPv4 packets into IPv6 packets and send them to the IPv6 network.
138 IPv4inIPv6 4in6 refers to tunneling of IPv4 in IPv6. It is an inherent internet interoperation mechanism allowing IPv4 to be used in an IPv6 only network. 4in6 uses tunneling to encapsulate IPv4 traffic over configured IPv6 tunnels. 4in6 tunnels are usually manually configured but they can be automated using protocols such as TSP to allow easy connection to a tunnel broker. DS – Lite DS –Lite, or Dual-Stack Lite, is designed to let an ISP omit the deployment of any IPv4 address to the customer’s CPE. Instead, only global IPv6 addresses are provided (Regular Dual-Stack Lite deploys global addresses for both IPv4 and IPv6). The CPE distributes private IPv4 addresses for the LAN clients, the same as a NAT device. The subnet information is chosen by the customer, identically to the NAT model. However, instead of performing the NAT itself, the CPE encapsulates the IPv4 packet inside an IPv6 packet. Click Add button to manually add the 4in6 rules. Tunnel Name: User-defined tunnel name. Mechanism: It is the 4in6 tunnel operation technology. Please select DS-Lite. Associated WAN Interface: The applied WAN interface with the set tunnel, and when there are packets from/to the WAN interface, the tunnel would be used to transport the packets. Associated LAN Interface: Specify the linked LAN interface with the tunnel. Method: Manually to specify the AFTP (Address Family Transition Router) address or Automatic. AFTR: Specify the address of AFTP (Address Family Transition Router) from your ISP.
139 Security IP Filtering Outgoing IP filtering enables you to configure your router to block specified internal/external users (IP address) from Internet access, or you can disable specific service requests (Port number) to /from Internet. The relationship among all filters is “or” operation, which means that the router checks these different filter rules one by one, starting from the first rule. As long as one of the rules is satisfied, the specified action will be taken. Note: The maximum number of entries: 32. Click Add button to enter the exact rule setting page. Filter Name: A user-defined rule name. User can select simply from the list box for the application for quick setup. IP Version: Select the IP Version, IPv4 or IPv6. Protocol: Set the traffic type (TCP/UDP, TCP, UDP, ICMP, RAW, Any) rule applies to. Source IP address: This is the Address-Filter used to allow or block traffic to/from particular IP address(es) featured in the IP range. If you leave empty, it means any IP address. Source Port [port or port:port]: The port or port range defines traffic from the port (specific application) or port in the set port range blocked to go through the router. Default is set port from range 1 – 65535. Destination IP address: Traffic from LAN with the particular traffic destination address specified in the IP range is to be blocked from going through the router, similarly set as the Source IP address above. Destination Port [port or port: port]: Traffic with the particular set destination port or port in the set port range is to be blocked from going through the router. Default is set port from port range: 1 –
140 65535. Time Schedule: Select or set exactly when the rule works. When set to “Always On”, the rule will work all time; and also you can set the precise time when the rule works, like 01:00 - 19:00 from Monday to Friday. Or you can select the already set timeslot in “Time Schedule” during which the rule works. And when set to “Disable”, the rule is disabled or inactive and there will be an icon” ” in list table indicating the rule is inactive. See Time Schedule. Action: Select to drop or forward the packets fit the outgoing filtering rule. Log: check the check-box to record the security log. To check the log, users can turn to Security Log. Example: For example, if there is an outgoing rule set as follows, then the 21 application between source IP and destination IP will be blocked. Or exactly in the rule below, all traffic trying to access FTP will be blocked. (The rule is active; disable field shows the status of the rule, active or inactive) Add another Outgoing IP Filtering rule, users will find the “arrow” icon to change the IP outgoing filter rule working orders.

FORWARDED means that all MAC layer frames will be forwarded except those matching with any of the specified rules in the following table. BLOCKED means that all MAC layer frames will be blocked except those matching with any of the specified rules in the following table. By default, all MAC frames of the interface in Bridge Mode will be forwarded, you can check Change checkbox and then press Change Policy to change the settings to the interface. For example, from above, the interface atm0.1 is of bridge mode, and all the MAC layer frames will be forward, but you can set some rules to let some item matched the rules to be blocked. Click Add button to add the rules. Protocol type: Select from the drop-down menu the protocol that applies to this rule. Destination /Source MAC Address: Enter the destination/source address. Frame Direction: Select the frame direction this rule applies, both LAN and WAN: LAN <=>WAN, only LAN to WAN: LAN=>WAN, only WAN to LAN: WAN=>LAN. WAN Interfaces: Select the interfaces configured in Bridge mode.
145 Blocking WAN PING This feature is enabled to let your router not respond to any ping command when someone others “Ping” your WAN IP.
146 Time Restriction A MAC (Media Access Control) address is the unique network hardware identifier for each PC on your network’s interface (i.e. its Network Interface Card or Ethernet card). Using your router’s MAC Address Filter function, you can configure the network to block specific machines from accessing your LAN during the specified time. This page adds time of day restriction to a special LAN device connected to the router. Please click Add button to add the device(s) to be subject to Time Restriction rules (forward or drop connection to internet). Devices Not added will not comply with the rules and access internet and router willingly. To find out the MAC address of a window based PC, go to command window, and type “ipconfig/all”. Note: The maximum entries configured: 32. Click Add to add the rules. Host Label: User-defined name. MAC Address: Enter the MAC address(es) you want to allow or block to access the router and LAN. The format of MAC address could be: xx:xx:xx:xx:xx:xx or xx-xx-xx-xx-xx-xx. For convenience, user can select from the list box. Time Schedule: Configure to control the PC from accessing router and internet.  Drop: To drop the MAC entries always; in other words, the MACs are blocked access to router and internet always.  Forward: To forward the MAC entries always; in other words, the MACs are granted access to the router and internet always.  Check or select from listbox: To set the time duration during which the MACs are blocked from access the router and internet. “select from listbox” means that you can select the already set timeslot in “Time Schedule” section during which the MACs are blocked from access the router and internet. Click Apply to confirm your settings. The following prompt window will appear to remind you of the attention.
147 An example: Here you can see that the user “child-use” with a MAC of 18:a9:05:04:12:23 is blocked to access the router from 00:00 to 23:59 Monday through Friday. The “test” can access the internet always. If you needn’t this rule, you can check the box, press Remove, it will be OK. .
148 URL 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. Note: 1) URL Filter rules apply to both IPv4 and IPv6 sources. 2) But in Exception IP Address part, user can click to set the exception IP address(es) for IPv4 and IPv6 respectively. Keywords Filtering: Allow blocking against 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. Domains Filtering: This function checks the whole URL address but not the IP address against your list of domains to block or allow. If it is matched, the URL request will either be sent (Trusted) or dropped (Forbidden). Restrict URL Features: Click Block Java Applet to filter web access with Java Applet components. Click Block ActiveX to filter web access with ActiveX components. Click Block Cookie to filter web access with Cookie components. Click Block Proxy to filter web proxy access. Exception IP Address: You can input a list of IP addresses as the exception list for URL filtering. These IPs will not be covered by the URL rules. Time Schedule: Select or set exactly when the rule works. When set to “Always On”, the rule will work all time; and also you can set the precise time when the rule works, like 01:00 - 19:00 from Monday to Friday. Or you can select the already set timeslot in “Time Schedule” during which the rule works. And when set to “Disable”, the rule is disabled. See Time Schedule. Log: Select Enable for this option if you will like to capture the logs for this URL filter policy. To check the log, users can turn to Security Log.
149 Keywords Filtering Note: Maximum number of entries: 32. Click to add the keywords. Enter the Keyword, for example image, and then click Add. You can add other keywords like this.

Type: select the action this filter deals with the Domain.  Forbidden Domain: The domain is forbidden access.  Trusted Domain: The domain is trusted and allowed access. Enter a domain and select whether this domain is trusted or forbidden with the pull-down menu. Next, click Add. Your new domain will be added to either the Trusted Domain or Forbidden Domain listing, depending on which you selected previously. For specific process, please refer to Keywords
150 Filtering. Exception IP Address In the section, users can set the exception IP respectively for IPv4 and IPv6. Click to add the IP Addresses. Enter the except IP address. Click Add to save your changes. The IP address will be entered into the Exception List, and excluded from the URL filtering rules in effect. For specific process, please refer to Keywords Filtering. For example, users can set IPv4 client 192.168.1.103 in your network as a exception address that is not limited to the rules set in URL filter ( or IPv4 clients (a range) ). And also an IPv6 client (2000:1211:1002:6ba4:d160:5adb:9009:87ae) or IPv6 clients(a range ) can be the exceptions from the URL rules. At the URL Filter page, press Apply to confirm your settings.
151 Parental Control Provider Parental Control Provider provides Web content filtering offering safer and more reliable web surfing for users. Please get an account and configure at the selected Provider “www.opendns.com” in advance. To use parental control (DNS), user needs to configure to use parental control (DNS provided by parental control provider) to access internet at WAN configuration or DNS page(See DNS). Host Name, Username and Password: Enter your registered domain name and your username and password at the provider website www.opendns.com.
152 QoS - Quality of Service Quality of Service QoS helps you to control the data upload traffic of each application from LAN (Ethernet) to WAN (Internet). This feature allows you to control the quality and speed of throughput for each application when the system is running with full upstream load. Note: VDSL/ADSL line speed is based on the VDSL/ADSL sync rate. EWAN Line Speed Upstream / Downstream: Specify the upstream and downstream rate of the EWAN interface. Click Apply to save the EWAN rate settings. Click Add to enter QoS rules. IP Version: Select either IPv4 or IPv6 base on need. Application: Assign a name that identifies the new QoS application rule. Select from the list box for quick setup. Direction: Shows the direction mode of the QoS application.  LAN to WAN: You want to control the traffic from local network to the outside (Upstream). You can assign the priority for the application or you can limit the rate of the application. Eg: you have a FTP server inside the local network, and you want to have a limited control by the QoS policy and so you need to add a policy with LAN to WAN direction setting.  WAN to LAN: Control traffic from WAN to LAN (Downstream). Protocol: Select the supported protocol from the drop down list. DSCP Marking: Differentiated Services Code Point (DSCP), it is the first 6 bits in the ToS byte.
153 DSCP Marking allows users to classify the traffic of the application to be executed according to the DSCP value. IP Precedence and DSCP Mapping Table Mapping Table Default (000000) Best EffortEF(101110) Expedited Forwarding AF11 (001010) Assured Forwarding Class1(L) AF12 (001100) Assured Forwarding Class1(M) AF13 (001110) Assured Forwarding Class1(H) AF21 (010010) Assured Forwarding Class1(L) AF22 (010100) Assured Forwarding Class1(M) AF23 (010110) Assured Forwarding Class1(H) AF31 (011010) Assured Forwarding Class1(L) AF32 (011100) Assured Forwarding Class1(M) AF33 (011110) Assured Forwarding Class1(H) AF41 (100010) Assured Forwarding Class1(L) AF42 (100100) Assured Forwarding Class1(M) AF43 (100110) Assured Forwarding Class1(H) CS1(001000) Class Selector(IP precedence)1 CS2(010000) Class Selector(IP precedence) 2 CS3(011000) Class Selector(IP precedence)3 CS4(100000) Class Selector(IP precedence) 4 CS5(101000) Class Selector(IP precedence) 5 CS6(110000) Class Selector(IP precedence) 6 CS7(111000) Class Selector(IP precedence) 7 DSCP offers three levels of service, Class Selector (CS), Assured Forwarding (AF) and Expedited Forwarding (EF). AF1, AF2, AF3 and AF4 are four levels of assured forwarding services. Each AF has three different packet loss priorities from high, medium, to low. Also, CS1-CS7 indicates the IP precedence. Rate Type: You can choose Limited or Prioritization.  Limited (Maximum): Specify a limited data rate for this policy. It also is the maximum rate for this policy. When you choose Limited, type the Ratio proportion. As above FTP server example, you may want to “throttle” the outgoing FTP speed to 20% of 256K and limit to it, you may use this type.  Prioritization: Specify the rate type control for the rule to used. If you choose Prioritization for the rule, you parameter Priority would be available, you can set the priority for this rule.  Set DSCP Marking: When select Set DSCP Marking, the packets matching the rule will be forwarded according to the pre-set DSCP marking. Ratio: The rate percent of each application/policy compared to total traffic on the interface with limited rate type. For example, we want to only allow 20% of the total data for the LAN-to-WAN direction to be used for FTP server. Then we can specify here with data ratio = 20. If you have ADSL LINE with 256K/bps.rate, the estimated data rate, in kbps, for this rule is 20%*256*0.9 = 46kbps. (For 0.9 is an estimated factor for the effective data transfer rate for an ADSL LINE from LAN to WAN. For WAN-to-LAN, it is 0.85 to 0.8) Priority: Set the priority given to each policy/application. Specify the priority for the use of bandwidth. You can specify which application can have higher priority to acquire the bandwidth. Its default setting is set to Normal. You may adjust this setting to fit your policy / application. Internal IP Address: The IP address values for Local LAN devices you want to give control.
154 Internal Port: The Port number on the LAN side, it is used to identify an application. External IP Address: The IP address on remote / WAN side. External Port: The Port number on the remote / WAN side. Time Schedule: Select or set exactly when the rule works. When set to “Always On”, the rule will work all time; and also you can set the precise time when the rule works, like 01:00 - 19:00 from Monday to Friday. Or you can select the already set timeslot in “Time Schedule” during which the rule works. And when set to “Disable”, the rule is disabled or inactive and there will be an icon” ” indicating the rule is inactive. See Time Schedule.
155 Examples: Common usage 1. Give outgoing VoIP traffic more priority. The default queue priority is normal, so if you have VoIP users in your local network, you can set a higher priority to the outgoing VoIP traffic. 2. Give regular web http access a limited rate
156 3. If you are actively engaged in P2P and are afraid of slowing down internet access for other users within your network, you can then use QoS to set a rule that has low priority. In this way, P2P application will not congest the data transmission with other applications. Other applications, like FTP, Mail access, users can use QoS to control based on need.
157 QoS Port Shaping QoS port shaping supports traffic shaping of Ethernet interfaces. It forcefully maximizes the throughput of the Ethernet interface. When “Shaping Rate” is set to “-1”, no shaping will be in place and the “Burst Size” is to be ignored. Interface: P1-P5. P5 used as EWAN also covered. Type: All LAN when P4 is LAN port; P4 used as EWAN, type WAN and all others LAN. QoS Shaping Rate (Kbps): Set the forcefully maximum rate. Burst Size(Bytes): Set the forcefully Burst Size.
158 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. Exceptional Rule Group Exceptional Rule is dedicated to giving or blocking NAT/DMZ access to some specific IP or IPs(range). Users are allowed to set 8 different exceptional rule groups at most. In each group, user can add specific IP or IP range. Press Edit to set the exceptional IP (IP Range). Default Action: Please first set the range to make “Default Action” setting available. Select “Allow” to grant access to the listed IP or IPs to Virtual Server and DMZ Host. While choose “Block” to ban the listed IP or IPs to access the Virtual Server and DMZ Host. Apply: Press Apply button to apply the change. Exceptional Rule Range IP Address Range: Specify the IP address range; IPv4 address range can be supported. Click Add to add the IP Range. For instance, if user wants block IP range of 172.16.1.102-172.16.1.106 from accessing your set virtual server and DMZ host, you can add this IP range and valid it.
159 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. Note: The maximum number of entries: 64. It is virtual server listing table as you see, Click Add to move on.
160 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) to apply. WAN IP: To specify the exact WAN IP address. It can be flexible while there are multiple WAN IPs on one interface. If the WAN IP field is empty, 8920AX(L) uses the current WAN IP of this interface. 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. User can select from the list box for quick setup. External Port  Start: Enter a port number as the external starting number for the range you want to give access to internal network.  End: Enter a port number as the external ending number for the range you want to give access to internal network. Internal Port  Start: Enter a port number as the internal staring number.  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. Time Schedule: Select or set exactly when the Virtual Server works. When set to “Always On”, the Virtual Server will work all time; and also you can set the precise time when Virtual Server works, like 01:00 - 19:00 from Monday to Friday. Or you can select the already set timeslot in Time Schedule during which the Virtual Server works. And when set to “Disable”, the rule is disabled and there will be an icon in the list table indicating the rule is disabled. See Time Schedule. Exceptional Rule Group: Select the exceptional group listed. It is to grant or block Virtual Server access to a group of IPs. For example, as we set previously group 1 blocking access to
161 172.16.1.102-172.16.1.106. If here you want to block Virtual Server access to this IP range, you can select Group1. 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.
162 (Means the rule is inactive) 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.
163 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 Firewall and NAT algorithms before being 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. Select from the list box to quick set the DMZ. Time Schedule: Select or set exactly when the DMZ works. When set to “Always On”, the DMZ will work all time; and also you can set the precise time when DMZ works, like 01:00 - 19:00 from Monday to Friday. Or you can select the already set timeslot in Time Schedule during which the DMZ works. And when set to “Disable”, the rule is disabled. See Time Schedule. Exceptional Rule Group: Select the exceptional group listed. It is to grant or block DMZ access to a group of IPs. For example, as we set previously group 1 blocking access to 172.16.1.102-172.16.1.106. If here you want to block DMZ Access to this IP range, you can select Group1. 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. Attention 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.
164 One-to-One NAT One-to-One NAT maps a specific private/local address to a global/public IP address. If user has multiple global/public IP addresses from your ISP, you are free to use one-to-one NAT to assign some specific public IP for an internal IP like a public web server mapped with a global/public IP for outside access. Valid: Check whether to valid the one-to-one NAT mapping rule. WAN Interface: Select one based WAN interface to configure the one-to-one NAT. Global IP address: The Global IP mapped to an internal device. It can be left empty, and under this circumstance, it can be reached through the WAN IP of interface set in the field above. Internal Address: The IP address of an internal device in the LAN. Exceptional Rule Group: Select the exceptional group listed. It is to give or block access to a group of IPs to the server after One-to-One NAT. For example, a server with 192.168.1.3 is mapped to 123.1.1.2 by One-to-One NAT, then the exceptional group can be designated to have or have not access to 123.1.1.2. For example, you have an ADSL connection of pppoe_0_8_35/ppp0.1 interface with three fixed global IP, and you then can assign the other two global IPs to two internal devices respectively. If you have a WEB server (IP address: 192.168.1.3) and a FTP server (IP address: 192.168.1.4) in local network, owning a public IP address range of 123.1.1.2 to 123.1.1.4 assigned by ISP. 123.1.1.2 is used as WAN IP address of the router, 123.1.1.3 is used for WEB server and 123.1.1.4 is used for FTP server. With One-to-One NAT, the servers with private IP addresses can be accessed at the corresponding valid public IP addresses
165 Port Triggering Port triggering is a way to automate port forwarding with outbound traffic on predetermined ports (‘triggering ports’), incoming ports are dynamically forwarded to the initiating host, while the outbound ports are in use. Port triggering triggers can open an incoming port when a client on the local network makes an outgoing connection on a predetermined port or a range of ports. Click Add to add a port triggering rule. Interface: Select from the drop-down menu the interface you want the port triggering rules apply to. Application: Preinstalled applications or Custom Application user can customize the utility yourself. Custom Application: It is a kind of service to let users themselves customizes the service they want. Enter the user-defined service name here. Trigger Port  Start: Enter a port number as the triggering port starting number.  End: Enter a port number as the triggering port ending number. Any port in the range delimited by the ‘Start’ and ‘End’ would be the trigger port.
166 Open port  Start: Enter a port number as the open port staring number.  End: Enter a port number as the open port ending number. Any port in the range delimited by the ‘Start’ and ‘End’ would be the preset forwarding port or open port. Protocol: select the protocol this service used: TCP/UDP, TCP, UDP. Set up An example of how port triggering works, when a client behind a NAT router connecting to Aim Talk, it is a TCP connection with the default port 4099. When connecting to Aim Talk, the client typically makes an outgoing connection on port 4099 to the Aim Talk server, but when the computer is behind the NAT, the NAT silently drops this connection because it does not know which computer behind the NAT to send the request to connect. So, in this case, port triggering in the router is working, when an outbound connection is attempted on port 4099 (or any port in the range set), it should allow inbound connections to that particular computer. 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.
167 Remove If you don’t need a specified Server, you can remove it. Check the check box beside the item you want to remove, and then press Remove.
168 ALG The ALG Controls enable or disable protocols over application layer. SIP: Enable the SIP ALG when SIP phone needs ALG to pass through the NAT. Disable the SIP when SIP phone includes NAT-Traversal algorithm. H.323: Enable to secure the voice communication using H.323 protocol when one or both terminals are behind a NAT.
169 Wake On LAN Wake on LAN (WOL, sometimes WoL) is an Ethernet computer networking standard that allows a computer to be turned on or woken up remotely by a network message. Host Label: Enter identification for the host. Select: Select MAC address of the computer that you want to wake up or turn on remotely. Wake by Schedule: Enable to wake up your set device at some specific time. For instance, user can set to get some device woken up at 8:00 every weekday. Click Schedule to enter time schedule configuring page to set the exact timeline. Add: After selecting, click Add then you can submit the Wake-up action. Edit/Delete: Click to edit or delete the selected MAC address. Ready: “Yes” indicating the remote computer is ready for your waking up. “No” indicating the machine is not ready for your waking up. Delete: Delete the selected MAC address.
