Manual Part 2

66 66  Public Port: Specify the public port number.  Private Port: Specify the private port number.  Schedule: Select a schedule to Always or Never from the drop-down list. If a schedule does not exist, you may create it in the Tools > Schedule section.  Inbound Filter: Select an inbound filter from the drop-down list. If an inbound filter does not exist, you may create it from Advanced > Inbound Filter section.  Click on the Add button to insert the entry into the Virtual Server list.
67 67 6.3.3. Special Applications An application rule is used to open single or multiple ports on your router when the router senses data sent to the Internet on a trigger port or port range. An application rule applies to all computers on your internal network.  Name: Assign a meaningful name to the virtual server, for example Web Server. Several well-known types of virtual server are available from the Application Name drop-down list. Selecting one of these entries fills some of the remaining parameters with standard values for that type of server.  Triggering Ports: Specify the outgoing port range that is used by the application.  Firewall Ports: Specify the port range that you would like to open for Internet traffic.  Schedule: Select a schedule to Always or Never from the drop-down list. If a schedule does not exist, you may create it in the Tools > Schedule section.  Click on the Add button to insert the entry into the Special Applications list.
68 68 6.3.4. Port Forwarding Multiple connections are required by some applications, such as internet games, video conferencing, Internet telephony, and others. These applications have difficulties working through NAT (Network Address Translation). This section is used to open multiple ports or a range of ports in your router and redirect data through those ports to a single PC on your network.  Name: Assign a meaningful name to the virtual server, for example Web Server. Several well-known types of virtual server are available from the Application Name drop-down list. Selecting one of these entries fills some of the remaining parameters with standard values for that type of server.  IP Address: Specify the IP address for the virtual server entry.  TCP/UDP Ports: Specify the TCP or UDP port numbers.  Schedule: Select a schedule to Always or Never from the drop-down list. If a schedule does not exist, you may create it in the Tools > Schedule section.
69 69  Inbound Filter: Select an inbound filter from the drop-down list. If an inbound filter does not exist, you may create it from Advanced > Inbound Filter section.  Click on the Add button to insert the entry into the Port Forwarding list.
70 70 6.3.5. StreamEngine The StreamEngine feature helps improve the network performance by prioritizing applications.  Enable Traffic Shaping: Place a check in the box to enable traffic shaping. When this option is enabled, the router restricts the flow of outbound traffic so as not to exceed the WAN uplink bandwidth.  Automatic Uplink Speed. Place a check in this box to enable automatic uplink speed. When enabled, this option causes the router to automatically measure the useful uplink bandwidth each time the WAN interface is re-established (after a reboot, for example).  Measured Uplink Speed: Displays the uplink speed. This is the uplink speed measured when the WAN interface was last re-established. The value may be lower than that reported by your ISP as it does not include all of the network protocol overheads
71 71 associated with your ISP's network. Typically, this figure will be between 87% and 91% of the stated uplink speed for xDSL connections and around 5 kbps lower for cable network connections.  Manual Uplink Speed: Specify an uplink speed or select it from the drop-down list. If Automatic Uplink Speed is disabled, this options allows you to set the uplink speed manually. Uplink speed is the speed at which data can be transferred from the router to your ISP.  Connection Type: By default, the router automatically determines whether the underlying connection is an xDSL/Frame-relay network or some other connection type (such as cable modem or Ethernet), and it displays the result as Detected xDSL or Frame Relay Network. If you have an unusual network connection in which you are actually connected via xDSL but for which you configure either Static or DHCP in the WAN settings, setting this option to xDSL or Other Frame Relay Network ensures that the router will recognize that it needs to shape traffic slightly differently in order to give the best performance. Choosing xDSL or Other Frame Relay Network causes the measured uplink speed to be reported slightly lower than before on such connections, but gives much better results.  Click on the Apply button to store these settings.
72 72  Enable StreamEngine: Place a check in this box to enable this option. Enable this option for better performance and experience with online games and other interactive applications, such as VoIP.  Automatic Classification: Place a check in this box to enable this option. This option is enabled by default so that your router will automatically determine which programs should have network priority.  Dynamic Fragmentation: Place a check in this box to enable this option. This option should be enabled when you have a slow Internet uplink. It helps to reduce the impact that large low priority network packets can have on more urgent ones by breaking the large packets into several smaller packets.
73 73  Add StreamEngine Rule: A StreamEngine Rule identifies a specific message flow and assigns a priority to that flow. For most applications, automatic classification will be adequate, and specific StreamEngine Rules will not be required. StreamEngine supports overlaps between rules, where more than one rule can match for a specific message flow. If more than one rule is found to match the rule with the highest priority will be used.  Enable: Place a check in this box to enable the StreamEngine rule.  Name: Specify a name for the rule.  Priority: Specify a priority for the rule. Being with 1 which is the highest and 255 the lowest priority.  Protocol: Specify a protocol or select one from the drop-down list.  Local IP Range: Specify the local (LAN) IP address range.  Local Port Range: Specify the local (LAN) port range.  Remote IP Range: Specify the remote (WAN) IP address range.  Remote Port Range: Specify the remote (WAN) port range.  Click on the Save button to insert the entry into the StreamEngine list.
74 74 6.3.6. Routing This section adds a new entry into the routing table.  Name: Specify a name for the rule.  Destination IP: Specify the destination IP address.  Netmask: Specify the subnet mask for the IP address.  Gateway: Specify the IP address of the gateway.  Metric: Specify the number of routing hops. The route metric is a value from 1 to 16 that indicates the cost of using this route. A value of 1 is the lowest cost, and 15 is the highest cost. A value of 16 indicates that the route is not reachable from this router. When trying to reach a particular destination, computers on your network will select the best route, ignoring unreachable routes.  Interface: Select the interface from the drop-down list.  Click on the Add button to insert the entry into the Routing table.
75 75 6.3.7. Access Control The Access Control section allows you to control access in and out of devices on your network. Use this feature as Parental Controls to only grant access to approved sites, limit web access based on time or dates, and/or block access from applications such as peer-to-peer utilities or games. When Access Control is disabled, every device on the LAN has unrestricted access to the Internet. However, if you enable Access Control, Internet access is restricted for those devices that have an Access Control Policy configured for them. All other devices have unrestricted access to the Internet.  Place a check in the Enable Access Control check box and then click on the Add Policy button. This will bring up the Add New Policy wizard.  The wireless wizard will inform you that there are six major steps in the process.  Choose a unique name for your policy  Select a schedule  Select the machine to which the policy applies  Select filtering method  Configure web access logging
76 76  Click on the Next button to continue.  Specify a policy name and then click on the Next button to continue.  Select a schedule from the drop-down list: Always or Never, or you may define a new schedule. Click on the Next button to continue.
77 77  Select a machine to which the policy applies.  Address Type: Select the IP address or MAC address radio button.  IP Address: If you selected IP address above, then specify the IP address here.  MAC Address: If you need to change the MAC address of the rounter's WAN-side Ethernet interface, either type in an alternate MAC address (for example, the MAC address of the router initially connected to the ISP) or click on Clone Your PCs MAC Address.  Click on the OK button to insert the entry into the table.  Click on the Next button to continue.
78 78  Select a filtering method:  Log Web Access Only: Select this radio but in order to log web access.  Block All Access: Select this radio but in order to block all web access.  Block Some Access: Select this radio but in order to block some web access.  Click on the Save button to store the changes.
79 79 6.3.8. Web Filter This is a type of parental control feature used to restrict certain websites form being accessed through your network. These filters can be used for securing and restricting your network. Website/URL/Domain: Specify the web address that you would like to filter. Do not use “http://” Click on the Save button to store the changes.
80 80 6.3.9. MAC Address Filter This feature is used to restrict certain MAC address from accessing the Internet. These filters can be used for securing and restricting your network.  Configure MAC Filtering: Select one of the options from the drop-down list.  Turn MAC Filtering OFF: When "OFF" is selected, MAC addresses are not used to control network access.  Turn MAC Filtering ON and ALLOW computers listed to access the network: When "ALLOW" is selected, only computers with MAC addresses listed in the MAC Filtering Rules list are granted network access.  Turn MAC Filtering ON and DENY computers listed to access the network: When "DENY" is selected, any computer with a MAC address listed in the MAC Filtering Rules list is refused access to the network.  MAC Address: Specify that MAC address that you would like to filter.  Click on the Save button to store the changes.
81 81 6.3.10. Firewall The device provides a tight firewall by virtue of the way NAT works. Unless you configure the router to the contrary, the NAT does not respond to unsolicited incoming requests on any port, thereby making your LAN invisible to Internet cyber attacks. However, some network applications cannot run with a tight firewall. Those applications need to selectively open ports in the firewall to function correctly. The options on this page control several ways of opening the firewall to address the needs of specific types of applications.  Enable SPI: Place a check in this box to enable SPI. SPI ("stateful packet inspection" also known as "dynamic packet filtering") helps to prevent cyber attacks by tracking more state per session. It validates that the traffic passing through that session conforms to the protocol. When the protocol is TCP, SPI checks that packet sequence numbers are within the valid range for the session, discarding those packets that do not have valid sequence numbers. Whether SPI is enabled or not, the router always tracks TCP connection states and ensures that each TCP packet's flags are valid for the current state.
82 82  TCP / UDP NAT Endpoint Filtering options control how the router's NAT manages incoming connection requests to ports that are already being used. Select one of the radio buttons.  End Point Independent Once a LAN-side application has created a connection through a specific port, the NAT will forward any incoming connection requests with the same port to the LAN-side application regardless of their origin. This is the least restrictive option, giving the best connectivity and allowing some applications (P2P applications in particular) to behave almost as if they are directly connected to the Internet.  Address Restricted The NAT forwards incoming connection requests to a LAN-side host only when they come from the same IP address with which a connection was established. This allows the remote application to send data back through a port different from the one used when the outgoing session was created.  Port And Address Restricted The NAT does not forward any incoming connection requests with the same port address as an already establish connection.  Note: Some of these options can interact with other port restrictions. Endpoint Independent Filtering takes priority over inbound filters or schedules, so it is possible for an incoming session request related to an outgoing session to enter through a port in spite of an active inbound filter on that port. However, packets will be rejected as expected when sent to blocked ports (whether blocked by schedule or by inbound filter) for which there are no active sessions. Port and Address Restricted Filtering ensures that inbound filters and schedules work precisely, but prevents some level of connectivity, and therefore might require the use of port triggers, virtual servers, or port forwarding to open the ports needed by the application. Address Restricted Filtering gives a compromise position, which avoids problems when communicating with certain other types of NAT router (symmetric NATs in particular) but leaves inbound filters and scheduled access working as expected.  Enable Port Preservation: Place a check in this box to enable Port Preservation. NAT Port preservation (on by default) tries to ensure that, when a LAN host makes an Internet connection, the same LAN port is also used as the Internet visible port. This ensures best compatibility for internet communications. Under some circumstances it may be desirable to turn off this feature.
83 83  Enable anti-spoof checking: Place a check in this box to enable anti-spoof checking. Enabling this option can provide protection from certain kinds of "spoofing" attacks. However, enble this option with care. With some modems, the WAN connection may be lost when this option is enabled. In that case, it may be necessary to change the LAN subnet to something other than 192.168.0.x (192.168.2.x, for example), to re-establish the WAN connection.  Enable DMZ Host: Place check in this box to enable DMZ host. DMZ host is a demilitarized zone used to provide Internet services without sacrificing unauthorized access to its local private network. Typically, the DMZ host contains devices accessible to Internet traffic, such as web, FTP, email and DNS servers.  DMZ IP Address: Specify the IP address of the DMZ host.  Non-UDP/TCP/ICMP LAN Sessions: Place a check in this box to enable this feature. When a LAN application that uses a protocol other than UDP, TCP, or ICMP initiates a session to the Internet, the router's NAT can track such a session, even though it does not recognize the protocol. This feature is useful because it enables certain applications (most importantly a single VPN connection to a remote host) without the need for an ALG.  Note: This feature does not apply to the DMZ host (if one is enabled). The DMZ host always handles these kinds of sessions.  Enabling this option (the default setting) enables single VPN connections to a remote host. (But, for multiple VPN connections, the appropriate VPN ALG must be used.) Disabling this option, however, only disables VPN if the appropriate VPN ALG is also disabled.
84 84  Application Layer Gateway (ALG) Configuration: Place a check in appropriate feature boxes to enable them. . Some protocols and applications require special handling of the IP payload to make them work with network address translation (NAT). Each ALG provides special handling for a specific protocol or application. A number of ALGs for common applications are enabled by default.  PPTP: Allows multiple machines on the LAN to connect to their corporate networks using PPTP protocol. When the PPTP ALG is enabled, LAN computers can establish PPTP VPN connections either with the same or with different VPN servers. When the PPTP ALG is disabled, the router allows VPN operation in a restricted way -- LAN computers are typically able to establish VPN tunnels to different VPN Internet servers but not to the same server. The advantage of disabling the PPTP ALG is to increase VPN performance. Enabling the PPTP ALG also allows incoming VPN connections to a LAN side VPN server (refer to Advanced → Virtual Server).  IPSec: (VPN) Allows multiple VPN clients to connect to their corporate networks using IPSec. Some VPN clients support traversal of IPSec through NAT. This option may interfere with the operation of such VPN clients. If you are having trouble connecting with your corporate network, try disabling this option. Check with the system administrator of your corporate network whether your VPN client supports NAT traversal.  RTSP: Allows applications that use Real Time Streaming Protocol to receive streaming media from the internet. QuickTime and Real Player are some of the common applications using this protocol.  Windows/MSN Messenger: Supports use on LAN computers of Microsoft Windows Messenger (the Internet messaging client that ships with Microsoft Windows) and MSN Messenger. The SIP ALG must also be enabled when the Windows Messenger ALG is enabled.  FTP: Allows FTP clients and servers to transfer data across NAT.  H.323 (Netmeeting): Allows H.323 (specifically Microsoft Netmeeting) clients to communicate across NAT server.  SIP: Allows devices and applications using VoIP (Voice over IP) to communicate across NAT. Some VoIP applications and devices have the ability to discover NAT devices and work around them. This ALG may interfere with the operation of such devices. If you are having trouble making VoIP calls, try turning this ALG off.  Wake-On-LAN: This feature enables forwarding of "magic packets" (that is, specially formatted wake-up packets) from the WAN to a LAN computer or other device that is "Wake on LAN" (WOL) capable.  MMS: Allows Windows Media Player, using MMS protocol, to receive streaming media from the internet.  Click on the Apply button to store these settings.
85 85 6.3.11. Inbound Filter When you use the Virtual Server, Port Forwarding, or Remote Administration features to open specific ports to traffic from the Internet, you could be increasing the exposure of your LAN to cyber attacks from the Internet. In these cases, you can use Inbound Filters to limit that exposure by specifying the IP addresses of internet hosts that you trust to access your LAN through the ports that you have opened. Inbound Filters can be used for limiting access to a server on your network to a system or group of systems. Filter rules can be used with Virtual Server, Gaming, or Remote Administration features.  Name Specify a name for the inbound filter.
86 86  Action: Select Allow or Deny from the drop-down list. This will apply the inbound filter rule on the WAN interface.  Remote IP Range: Specify the remote IP address range and then click in the check box to enable the range.  Click on the Save button to store the changes. 6.3.12. WISH WISH is short for Wireless Intelligent Stream Handling, a technology developed to enhance your experience of using a wireless network by prioritizing the traffic of different applications.  Enable WISH: Place a check in this box to enable the WISH feature.
87 87  HTTP: Place a check in this box to add HTTP as a classifier. This allows the device to recognize HTTP transfers for many common audio and video streams and prioritize them above other traffic. Such streams are frequently used by digital media players.  Windows Media Center: Place a check in this box to add HTTP as a classifier. This enables the router to recognize certain audio and video streams generated by a Windows Media Center PC and to prioritize these above other traffic. Such streams are used by systems known as Windows Media Extenders, such as the Xbox 360.  Automatic: Place a check in this box for the device to automatically configure the classifiers. When enabled, this option causes the router to automatically attempt to prioritize traffic streams that it doesn't otherwise recognize, based on the behavior that the streams exhibit. This acts to deprioritize streams that exhibit bulk transfer characteristics, such as file transfers, while leaving interactive traffic, such as gaming or VoIP, running at a normal priority.  Enable: Place a check in this box to enable the WISH rule. A WISH Rule identifies a specific message flow and assigns a priority to that flow. For most applications, the priority classifiers ensure the right priorities and specific WISH Rules are not required. WISH supports overlaps between rules. If more than one rule matches for a specific message flow, the rule with the highest priority will be used.  Name: Assign a meaningful name to the WISH rule.  Priority: Select a priority from the drop-down list. The four priority message flows are:  BK: Background (least urgent).  BE: Best Effort.  VI: Video.  VO: Voice (most urgent).  Protocol: Select a protocol from the drop-down list.  Hos1 IP Range: Specify the IP range for the rule.  Host 1 Port Range: Specify the port range for the rule.  Host 2 IP Range: Specify the IP range for the rule.  Host 2 Port Range: Specify the port range for the rule.  Click on the Save button to insert the entry into the WISH rules list.
88 88 6.3.13. Wi-Fi Protected Setup Wi-Fi Protected Setup is a feature that locks the wireless security settings and prevents the settings from being changed by any new external registrar using its PIN. Devices can still be added to the wireless network using Wi-Fi Protected Setup.  Enable: Place a check in this box to enable this feature.  Lock: Place a check in this box to lock the wireless security settings and prevents the settings from being changed by any new external registrar using its PIN. Devices can still be added to the wireless network using Wi-Fi Protected Setup.  Reset PIN to Default: Press this button to reset the PIN to it’s default setting.  Generate NEW PIN: Press this button to generate a new random PIN.  Add Wireless Device Wizard: Please refer to Chapter 4 in order to configure Wi-Fi Protected Setup using the Wizard.  Click on the Apply button to store these settings.
89 89 6.3.14. Advanced Network (UPNP, WAN Ping…) In this section you can configure the UPNP, WAN Ping, WAN port speed, multicast streams, and PPPoE pass-through settings.  Enable UPnP: Place a check in this box to enable UPnP. UPnP stands for Universal Plug and Play, which is a networking architecture that provides compatibility among networking equipment, software, and peripherals. This router has optional UPnP capability, and can work with other UPnP devices and software.  Allow Users to disable Internet Access: Place a check in this box if you would like to allow to user to terminate the WAN session.  Allow Users to modify Virtual Server Mappings: Place a check in this box if you would like the users to add, modify, or delete server mapping entries.  Enable WAN Ping Respond: Place a check in this box if you would like this device to be pinged from the WAN side.  WAN Ping Inbound Filter: You may select the computer that may ping this device from the WAN side.  WAN Port Speed: You may select a WAN port speed from the drop-down list. It is recommended that you select Auto.
90 90  Enable Multicast Streams: Place a check in this box to enable multicast streams. The router uses the IGMP protocol to support efficient multicasting -- transmission of identical content, such as multimedia, from a source to a number of recipients. This option must be enabled if any applications on the LAN participate in a multicast group. If you have a multimedia LAN application that is not receiving content as expected, try enabling this option.  Enable PPPoE Pass Through: Place a check in this box to enable PPPoE pass-through. This option controls whether LAN computers can act as PPPoE clients and negotiate the PPP sessions through the router over the WAN ethernet link. Enabling this option allows LAN computers to act as PPPoE clients. Disabling this option prevents LAN computers from establishing PPPoE pass-through connections.  Click on the Apply button to store these settings.
