The IP Allocation window for the client opens. 3. Scroll through the New Allocation values and select the address or method to use for the client’s DHCP assignment: • Click Address from DHCP Pool to set the client to accept any valid DHCP address available (standard operation). • Click any of the private fixed IP addresses (192.168.1.64 to 192.168.1.253) shown in the list to allocate that IP address to the selected client. 4. Click the Save button to save the IP allocation settings. A red “Changes saved” message appears at the top of the IP Allocation page. 51 Administrator’s Handbook Link: HPNA When you click the HPNA link, the HPNA Network page appears. The HPNA Network page displays information about the NVG599 gateway’s HPNA-connected devices in 15- minute intervals. You can test the performance of each station to station pair by clicking the Run extended Test button. 52 The following page appears as a warning about this invasive test. If you do not run the extended test, the station-to-station performance section is not displayed. You can generate updated statistics by clicking the Refresh button. HomePNA statistics for the current and previous intervals are displayed below the following static values: Station ID HPNA MAC Address HPNA Firmware (C-coax, T=TP) HPNA Version HPNA Master Interval statistic fields supply the following information: Label Statistic Displayed Short Tx Pkt Transmitted Packets Short Rx Pkt Received Packets CRC Errors Rx Receipt errors Dropped Tx Transmit packets dropped Dropped Rx Receipt packets dropped Tx Error % Percentage of transmitted errors Rx Error % Percentage of receipt errors Frames Tx Number of frames transmitted Frames Rx Number of frames received Bytes Tx Bytes transmitted Bytes Rx Bytes received Unicast Tx Number of unicast packets transmitted Unicast Rx Number of unicast packets received Multicast Tx Number of multicast packets transmitted Multicast Rx Number of multicast packets received Local Control Req Number of requests made to the device by local control Local Control Repl Number of replies made by the device to local control 53 Administrator’s Handbook Label Statistic Displayed Remote Control Req Number of requests made to the device by remote control Remote Control Repl Number of replies made by the device to remote control Voice When you click the Voice tab, the Voice Status page appears. Voice-over-IP (VoIP) refers to voice telephone calls transmitted over the Internet. This type of service differs from traditional phone service that uses the Public Switched Telephone Network (PSTN). VoIP calls use an Internet protocol, Session Initiation Protocol (SIP), to transmit sound over a network or the Internet in the form of data packets. The Voice page displays information about your VoIP phone lines, if configured. Your device supports two phones, Line 1 and Line 2. If either one or both are registered with a SIP server by your service provider or not registered, the Voice page will display their Registration Details. The links at the top of the Voice page provide access to a series of pages that allow you to configure and monitor features of your device. The links bar on the Voice page includes the following links. For more information about each link, see the related section in this guide. Line Details (see page 55) Call Statistics (see page 56) 54 Link: Line Details When you click the Line Details link, the Line Details page appears. If your service provider has enabled your VoIP phone lines, you can register them by clicking the Register Line 1 or Register Line 2 button. To test if the lines are enabled, click the Ring Line 1 or Ring Line 2 button. If enabled and registered, the respective phone will ring for 30 seconds. To clear the current state of each phone line, click the Reset Line 1 or Reset Line 2 button. This will disconnect any calls currently in progress as well. To update the display, click the Refresh button. 55 Administrator’s Handbook Link: Call Statistics When you click Call Statistics, the Call Statistics page appears. For Line 1 and Line 2, the two available phone lines, the Call Statistics page displays the following information: Call Statistics - Line 1 and Line 2 Last Call/Cumulative – Incoming/Outgoing RTP Packet Loss Real-time Transport Protocol packets dropped RTP Packet Loss percentage Percent of Real-time Transport Protocol packets dropped Total RTCP Packets Total Real-time Transport Control Protocol packets Average Inter Arrival Jitter Calculated continuously in milliseconds as each data packet is received and averaged. Max Inter Arrival Jitter The maximum value in milliseconds recorded as each data packet is received. Sum of Inter Arrival Jitter Calculated continuously in milliseconds as each data packet is received and totalled. Sum of Inter Arrival Jitter Calculated continuously in milliseconds as each data packet is received and the total is Squared squared. Sum of Frac Loss Fraction Lost: The fraction of RTP data packets lost since the previous SR or RR packet was sent. This fraction is defined to be the number of packets lost divided by the num- ber of packets expected. This number will be calculated on every RTCP SR packet. Sum of the fraction lost is calculated with all the RTCP packets. Sum of Frac Loss Squared Fraction lost is squared with every RTCP SR or RR packet. Sum of all values will give the Sum of Franc Loss Squared. 56 Max One Way Delay One-way delay will be calculated in milliseconds on every RTCP SR or RR packet. This value is (systime - lsr - dslr) / 2 lsr means last SR timestamp dslr means delay since last SR. Sum of One Way Delay The sum of all the one-way delays calculated in milliseconds on every RTCP packet is displayed as Sum of One Way Delay. Sum of One Way Delay One-way delay is squared with every RTCP SR or RR packet. Sum of all values will give Squared the Sum of One Way Delay Squared. Avg Round Trip Time Average time in milliseconds from this local source to destination address and back again for all logged calls Max Round Trip Time Maximum amount of time in milliseconds from this local source to destination address and back again for all logged calls Sum of Round Trip Time Sum of time in milliseconds from this local source to destination address and back again for all logged calls Sum of Round Trip Time Sum squared of time from this local source to destination address and back again for Squared all logged calls For Line 1 and Line 2, the two available phone lines, the Call Summary section displays the following information: Call Summary - Line 1 and Line 2 Current Call/Last Completed Call Call Timestamp Date and time of the current call Type May be Incoming or Outgoing Duration Length of time in seconds of call connection Codec in Use Audio codec used for decoding the call packet traffic. Far-End Host Information SIP server IP information: IP address and port number Far-End Caller Information Caller ID information, if available Cumulative Since Last Reset 57 Administrator’s Handbook Last Reset Timestamp Date and time of the last call Number of Calls Total number of calls for each VoIP line Duration Time in seconds since the last call Number of Incoming Calls Failed Number of incoming calls that fail to connect Number of Outgoing Calls Failed Number of outgoing calls that fail to connect The following table shows VoIP line states during various conditions.

The Firewall page displays the status of your system firewall elements. All computer operating systems are vulnerable to attack from outside sources, typically at the operating system or Internet Protocol (IP) layers. Stateful Inspection firewalls intercept and analyze incoming data packets to determine whether they should be admitted to your private LAN, based on multiple criteria, or blocked. Stateful inspection improves security by tracking data packets over a period of time, examining incoming and outgoing packets. Outgoing packets that request specific types of incoming packets are tracked; only those incoming packets constituting a proper response are allowed through the firewall. Stateful inspection is a security feature that prevents unsolicited inbound access when network address translation (NAT) is disabled. You can configure UDP and TCP “no-activity” periods that will also apply to NAT timeouts if stateful inspection is enabled on the interface. Stateful Inspection parameters are active on a WAN interface only if enabled on your system. Stateful inspection can be enabled on a WAN interface whether NAT is enabled or not. The Firewall Status page shows whether the each firewall feature is On or Off. The links at the top of the Firewall page provide access to series of pages that allow you to configure security features of your device.
