6Chapter 1 Introduction The WR-6891u is an 802.11n 2.4GHz concurrently compliant VoIP Gateway. It employs a 10/100/1000 Base-T Gigabit Ethernet port for WAN, four 10/100/1000 Base-T Gigabit Ethernet ports for LAN, one USB Host, one WiFi On-Off/WPS button, and an integrated 802.11n 2.4GHz(2T2R) for WLAN Access Point (AP), which is backward compatible with 802.11b/g; therefore WR-6891u allows both wired LAN connectivity and wireless connectivity. It is also capable of facilitating predictable, real-time, toll-quality voice over the Internet. WR-6891u connects to xDSL or GPON (Gigabit-Capable Passive Optical Network) modem and supports state-of-the-art security features such as WPA data encryption, Firewall & VPN pass through. It is designed for both residential and business applications that require wireless and wired connectivity. WR-6891u is also designed with a TR-068 compliant color panel and LED indicators for easy installation and user-friendliness. WR-6891u supports Triple services (Data+VoIP+IPTV) by wired or wireless protocol.

71.1 Application The following diagram depicts the application of the WR-6891u with GPON.

535.4 Wireless 5.4.1 Basic The Basic option allows you to configure basic features of the wireless LAN interface. Among other things, you can enable or disable the wireless LAN interface, hide the network from active scans, set the wireless network name (also known as SSID) and restrict the channel set based on country requirements. Click Apply/Save to apply the selected wireless options. Consult the table below for descriptions of these options. Option Description Enable Wireless A checkbox  that enables or disables the wireless LAN interface. When selected, a set of basic wireless options will appear.

54Option Description Hide Access Point Select Hide Access Point to protect the access point from detection by wireless active scans. To check AP status in Windows XP, open Network Connections from the start Menu and select View Available Network Connections. If the access point is hidden, it will not be listed there. To connect a client to a hidden access point, the station must add the access point manually to its wireless configuration. Clients Isolation When enabled, it prevents client PCs from seeing one another in My Network Places or Network Neighborhood. Also, prevents one wireless client communicating with another wireless client. Disable WMM Advertise Stops the router from ‘advertising’ its Wireless Multimedia (WMM) functionality, which provides basic quality of service for time-sensitive applications (e.g. VoIP, Video). Enable Wireless Multicast Forwarding Select the checkbox  to enable this function. SSID [1-32 characters] Sets the wireless network name. SSID stands for Service Set Identifier. All stations must be configured with the correct SSID to access the WLAN. If the SSID does not match, that user will not be granted access. BSSID The BSSID is a 48-bit identity used to identify a particular BSS (Basic Service Set) within an area. In Infrastructure BSS networks, the BSSID is the MAC (Media Access Control) address of the AP (Access Point); and in Independent BSS or ad hoc networks, the BSSID is generated randomly. Country US= worldwide Wireless - Guest / Virtual Access Points This router supports multiple SSIDs called Guest SSIDs or Virtual Access Points. To enable one or more Guest SSIDs select the checkboxes  in the Enabled column. To hide a Guest SSID, select its checkbox  in the Hidden column. Do the same for Isolate Clients and Disable WMM Advertise. For a description of these two functions, see the previous entries for “Clients Isolation” and “Disable WMM Advertise”. Similarly, for Enable WMF, Max Clients and BSSID, consult the matching entries in this table. NOTE: Remote wireless hosts cannot scan Guest SSIDs.

555.4.2 Security The following screen appears when Wireless Security is selected. The options shown here allow you to configure security features of the wireless LAN interface. Please see 6.10.3 WPS for WPS setup instructions. Click Apply/Save to implement new configuration settings. WIRELESS SECURITY Setup requires that the user configure these settings using the Web User Interface (see the table below). Select SSID Select the wireless network name from the drop-down menu. SSID stands for Service Set Identifier. All stations must be configured with the correct SSID to access the WLAN. If the SSID does not match, that client will not be granted access. Network Authentication This option specifies whether a network key is used for authentication to the wireless network. If network authentication is set to Open, then no authentication is provided. Despite this, the identity of the client is still verified. Each authentication type has its own settings. For example, selecting 802.1X authentication will reveal the RADIUS Server IP address, Port and Key fields. WEP Encryption will also be enabled as shown below.

56 The settings for WPA authentication are shown below. The settings for WPA2-PSK authentication are shown next.

57WEP Encryption This option specifies whether data sent over the network is encrypted. The same network key is used for data encryption and network authentication. Four network keys can be defined although only one can be used at any one time. Use the Current Network Key list box to select the appropriate network key. Security options include authentication and encryption services based on the wired equivalent privacy (WEP) algorithm. WEP is a set of security services used to protect 802.11 networks from unauthorized access, such as eavesdropping; in this case, the capture of wireless network traffic. When data encryption is enabled, secret shared encryption keys are generated and used by the source station and the destination station to alter frame bits, thus avoiding disclosure to eavesdroppers. Under shared key authentication, each wireless station is assumed to have received a secret shared key over a secure channel that is independent from the 802.11 wireless network communications channel. Encryption Strength This drop-down list box will display when WEP Encryption is enabled. The key strength is proportional to the number of binary bits comprising the key. This means that keys with a greater number of bits have a greater degree of security and are considerably more difficult to crack. Encryption strength can be set to either 64-bit or 128-bit. A 64-bit key is equivalent to 5 ASCII characters or 10 hexadecimal numbers. A 128-bit key contains 13 ASCII characters or 26 hexadecimal numbers. Each key contains a 24-bit header (an initiation vector) which enables parallel decoding of multiple streams of encrypted data. Please see 6.10 for MAC Filter, Wireless Bridge and Advanced Wireless features.

585.5 Parental Control This selection provides WAN access control functionality. 5.5.1 Time Restriction This feature restricts access from a LAN device to an outside network through the device on selected days at certain times.

63Chapter 6 Advanced Setup You can reach this page by clicking on the following icon located at the top of the screen. 6.1 Auto-detection setup The auto-detection function is used for CPE to detect WAN service for either ETHWAN or xDSL interface. The feature is designed for the scenario that requires only one WAN service in different applications. The Auto Detection page simply provides a checkbox allowing users to enable or disable the feature. Check the checkbox to display the following configuration options.

64 Enter the PPP username/password given by your service provider for PPP service detection. Select a LAN-as-WAN Ethernet port for auto-detect: Select the Ethernet Port that will be used as ETHWAN during auto-detection.

65 WAN services list: A maximum of 7 WAN services with corresponding VLAN ID (-1 indicates no VLAN ID is required for the service) are required to be configured for ETHWAN. The services will be detected in order. Users can modify the 7 pre-configured services and select disable to ignore any of the services to meet their own requirements. Click "Apply/Save" to activate the auto-detect function. Auto Detection status and Restart The Auto-detection status is used to display the real time status of the Auto-detection feature. The Restart button is used to detect all the WAN services that are either detected by the auto-detection feature or configured manually by users. The following window will pop up upon clicking the Restart button. Click the OK button to proceed.

66 Auto Detection notice Note: The following description concerning ETHWAN is for multiple LAN port devices only. 1) This feature will automatically detect one WAN service only. If customers require multiple WAN services, manual configuration is required. 2) If a physical ETHWAN port is detected, the Auto Detection for ETHWAN will be fixed on the physical ETHWAN port and cannot be configured for any LAN port; if the physical ETHWAN port is not detected, the Auto Detection for ETHWAN will be configured to the 4th LAN port by default and allows it to be configured for any LAN port as well. 3) For cases in which both the DSL port and ETHWAN port are plugged in at the same time, the DSL WAN will have priority over ETHWAN. For example, the ETHWAN port is plugged in with a WAN service detected automatically and then the DSL port is plugged in and linked up. The Auto Detection feature will clear the WAN service for ETHWAN and re-detect the WAN service for DSL port. 4) If none of the pre-configured services are detected, a Bridge service will be created.

676.2 Security To display this function, you must enable the firewall feature in WAN Setup. For detailed descriptions, with examples, please consult Appendix A - Firewall. 6.2.1 IP Filtering This screen sets filter rules that limit IP traffic (Outgoing/Incoming). Multiple filter rules can be set and each applies at least one limiting condition. For individual IP packets to pass the filter all conditions must be fulfilled. NOTE: This function is not available when in bridge mode. Instead, MAC Filtering performs a similar function. OUTGOING IP FILTER By default, all outgoing IP traffic is allowed, but IP traffic can be blocked with filters. To add a filter (to block some outgoing IP traffic), click the Add button. On the following screen, enter your filter criteria and then click Apply/Save.

68Consult the table below for field descriptions. Field Description Filter Name The filter rule label IP Version Select from the drop down menu. Protocol TCP, TCP/UDP, UDP, or ICMP.

At the bottom of this screen, select the WAN and LAN Interfaces to which the filter rule will apply. You may select all or just a subset. WAN interfaces in bridge mode or without firewall enabled are not available.

706.2.2 MAC Filtering NOTE: This option is only available in bridge mode. Other modes use IP Filtering to perform a similar function. Each network device has a unique 48-bit MAC address. This can be used to filter (block or forward) packets based on the originating device. MAC filtering policy and rules for the WR-6891u can be set according to the following procedure. The MAC Filtering Global Policy is defined as follows. FORWARDED means that all MAC layer frames will be FORWARDED except those matching the MAC filter rules. BLOCKED means that all MAC layer frames will be BLOCKED except those matching the MAC filter rules. The default MAC Filtering Global policy is FORWARDED. It can be changed by clicking the Change Policy button. Choose Add or Remove to configure MAC filtering rules. The following screen will appear when you click Add. Create a filter to identify the MAC layer frames by specifying at least one condition below. If multiple conditions are specified, all of them must be met. Click Save/Apply to save and activate the filter rule.

71 Click Save/Apply to save and activate the filter rule. Consult the table below for detailed field descriptions. Field Description Protocol Type PPPoE, IPv4, IPv6, AppleTalk, IPX, NetBEUI, IGMP Destination MAC Address Defines the destination MAC address Source MAC Address Defines the source MAC address Frame Direction Select the incoming/outgoing packet interface WAN Interfaces Applies the filter to the selected bridge interface

726.3 Quality of Service (QoS) NOTE: QoS must be enabled in at least one PVC to display this option. (see Appendix E - Connection Setup for detailed PVC setup instructions). To Enable QoS tick the checkbox and select a Default DSCP Mark. Click Apply/Save to activate QoS. QoS and DSCP Mark are defined as follows: Quality of Service (QoS): This provides different priority to different users or data flows, or guarantees a certain level of performance to a data flow in accordance with requests from Queue Prioritization. Default Differentiated Services Code Point (DSCP) Mark: This specifies the per hop behavior for a given flow of packets in the Internet Protocol (IP) header that do not match any other QoS rule.

736.3.1 QoS Queue Setup Configure queues with different priorities to be used for QoS setup. In ATM mode, maximum 16 queues can be configured. In PTM mode, maximum 8 queues can be configured. For each Ethernet interface, maximum 3 queues can be configured. To add a queue, click the Add button. To remove queues, check their remove-checkboxes (for user created queues), then click the Remove button. The Enable button will scan through every queues in the table. Queues with enable-checkbox checked will be enabled. Queues with enable-checkbox un-checked will be disabled. The enable-checkbox also shows status of the queue after page reload. Note that if WMM function is disabled in Wireless Page, queues related to wireless will not take effect. This function follows the Differentiated Services rule of IP QoS. You can create a new Queue entry by clicking the Add button. Enable and assign an interface and precedence on the next screen. Click Save/Reboot on this screen to activate it.

74Click Add to display the following screen. Name: Identifier for this Queue entry. Enable: Enable/Disable the Queue entry. Interface: Assign the entry to a specific network interface (QoS enabled).

776.3.3 QoS Classification The network traffic classes are listed in the following table. Click Add to configure a network traffic class rule and Enable to activate it. To delete an entry from the list, click Remove. This screen creates a traffic class rule to classify the upstream traffic, assign queuing priority and optionally overwrite the IP header DSCP byte. A rule consists of a class name and at least one logical condition. All the conditions specified in the rule must be satisfied for it to take effect. Click Apply/Save to save and activate the rule.

78 Field Description Traffic Class Name Enter a name for the traffic class. Rule Order Last is the only option. Rule Status Disable or enable the rule. Classification Criteria Class Interface Select an interface: (i.e.LAN, WAN, local, ETH1, ETH2, ETH3, wl0) Ether Type Set the Ethernet type (e.g. IP, ARP, IPv6). Source MAC Address A packet belongs to SET-1, if a binary-AND of its source MAC address with the Source MAC Mask is equal to the binary-AND of the Source MAC Mask and this field. Source MAC Mask This is the mask used to decide how many bits are checked in Source MAC Address. Destination MAC Address A packet belongs to SET-1 then the result that the Destination MAC Address of its header binary-AND to the Destination MAC Mask must equal to the result that this field binary-AND to the Destination MAC Mask. Destination MAC Mask This is the mask used to decide how many bits are checked in Destination MAC Address. Classification Results Specify Class Queue Packets classified into a queue that exit through an interface for which the queue is not specified to exist, will instead egress to the default queue on the interface. Specify Class Policer Packets classified into a policer will be marked based on the conforming action of the policer Mark Differentiated Service Code Point The selected Code Point gives the corresponding priority to packets that satisfy the rule. Mark 802.1p Priority Select between 0-7. Set Rate Limit The data transmission rate limit in kbps.

796.4 Routing The following routing functions are accessed from this menu: Default Gateway, Static Route, Policy Routing, RIP and IPv6 Static Route. NOTE: In bridge mode, the RIP menu option is hidden while the other menu options are shown but ineffective. 6.4.1 Default Gateway Default gateway interface list can have multiple WAN interfaces served as system default gateways but only one will be used according to the priority with the first being the highest and the last one the lowest priority if the WAN interface is connected. Priority order can be changed by removing all and adding them back in again.
