When you are in the configuration page, enter the VPI/VCI parameters and select the connection mode and encapsulation mode to ensure your packet is transmitted in a more efficient rate. Single click “submit” button to complete the settings.
Figure 4-6 ATM PVC Configuration under PPPoA Mode Huawei Technologies Proprietary 28
Figure 4-7 ATM PVC Configuration PPPoE Mode II. MAC Encapsulation Routing (MER) Mode It is recommended that you configure as being assigned an automatic IP address. If you want to manually configure to MER mode, please ask the WAN IP address, subnet mask, gateway address and DNS server address from your ISP.
You are free to skip the blank items on the configuration and HG520 will use the factory default settings for operation. Generally speaking, the default connection and service modes will satisfy your demand. However, you can configure settings based on Internet Service Provider’s request if there is such need.
III. IPoA (Internet Protocols over ATM) Mode It is recommended that you use the default DNS server and gateway, which means you do not need to make configuration. If you want to manually configure to IPoA mode, please ask the WAN IP address, subnet mask, gateway address and DNS server address from your ISP.
IV. Bridging Mode Please install PPPoE dial-up software if you use Bridging mode. If you select the static IP address, please ask the IP address of your computer, subnet mask, and DNS server address from your ISP. Figure 4-10 ATM PVC Configuration -- Bridging Mode 4.3.3 LAN Setting It refers to the configurations on the LAN port, for which you can set up the IP address and subnet mask. Enter the proper IP address and subnet mask in the space as shown in Figure 4-11.
Figure 4-11 LAN Setting 4.3.4 DHCP Setting DHCP is short for Dynamic Host Configuration Protocol. It is for assigning dynamic IP addresses to devices on a network. With dynamic addressing, a device can have a different IP address every time it connects to the network. Dynamic addressing simplifies network administration because the software keeps track of IP addresses rather than requiring an administration to manage the task.
Figure 4-12 DHCP Sever Setting 2) DHCP Relay DHCP relay is a relay agent for DHCP packets. It is used on a subnet with DHCP clients to "relay" their requests to a subnet that has a DHCP server on it. Because DHCP packets can be broadcast, they will not be routed off of the local subnet. The DHCP relay takes care of this for the client. Enter the DHCP Server IP address and click “Submit” to activate the settings. This function does not work when the PVC setting of NAT feature is configured in the HG520.
Figure 4-13 DHCP Relay Setting 4.3.5 DNS Settings DNS (Domain Name System) is an Internet service that translates domain names into IP addresses. Because domain names are alphabetic, they are easier to remember. The Internet, however, is based on IP addresses. Every time you use a domain name, therefore, a DNS service must translate the name into the corresponding IP address. Enter the DNS server IP address provided by the ISP on the DNS Settings page and single click Submit to complete the settings.
4.3.6 NAT NAT (Network Address Translation) is an Internet standard that enables a local-area network (LAN) to use one set of IP addresses for internal traffic and a second set of addresses for external traffic. A NAT box located where the LAN meets the Internet makes all necessary IP address translations. There are three different setting options under the NAT: z DMZ z NAPT z REDIRECT DMZ (Demilitarized Zone) refers to an isolated area.
NAPT (Network Address and Port Translation) is an extension to basic NAT, in that many network addresses and their TCP/UDP ports are translated to a single network address and its TCP/UDP ports. Please be noted that this feature works only when the PVC with NAT feature is activated. Figure 4-16 NAT- NAPT Settings REDIRECT refers to redirect the packets.
Figure 4-17 Advanced Setup — NAT — Multi NAT Single click New to open a REDIRECT setup page as shown in Figure 4-18. Here is the task you want to fulfill: the HTTP service is activated on the No.80 port of IP address of 192.168.1.2. User communicates with No.30 port of IP address of 10.132.41.116 via the Internet. When receiving such communication request, HG520 will redirect the request to the No.80 port of IP address of 192.168.1.2 and feedback to No.30 port of IP address of 10.132.41.
Figure 4-18 NAT-REDIRECT Setting 4.3.7 IP Route Settings IP Route settings include the setting of destination, netmask, next hop, IF name and route type. Single click New button on Figure 4-19 to create a new IP route. Enter the settings and single click Submit to complete the settings.
Figure 4-20 IP Route Adding 4.4 Advanced Settings Advanced Settings allow you to configure SCL, RIP, ACL, SNTP, IP Filter, Multinat, parental control setting and blocked protocol. 4.4.1 SCL (Service Control List) Setting This feature allows you to assign LAN port or WAN port as the interface when you visit the services (such as FTP, FTTP and ICMP, etc.).
Figure 4-21 SCL Setting 4.4.2 RIP RIP (Routing Information Protocol) is an Interior gateway protocol that specifies how routers exchange routing table information. With RIP, routers periodically exchange entire tables.
Figure 4-22 RIP Setting 4.4.3 QoS Setting QoS (Quality of Service) refers to that the network guarantees the expected bandwidth, delay, delay fluctuation (延遲抖動), and rate of packet loss are reachable during the Internet communication process.
Single click Add to open a QoS configuration page. Select the parameter based on your actual situation and demand, and enter the IP address, subnet mask and UDP/TCP code. When you are done, single click Submit at the bottom of the page to save the changes.
4.4.4 ACL (Access Control List) Setting We may configure ACL on HG520 to avoid any unauthorized user to control the device. ACL keeps the records of the unique authentication code, limit of authority, and expiry of such authentication of the authorized user. With this feature configured, HG520 will only allow the access of authorized user and avoid any illegal access.
Figure 4-25 SNTP Setting 4.4.6 IP Filter IP Filter is a software package that can be used to provide network address translation (NAT) or firewall services. It restricts the IP address of a computer or the IP address of a segment to access the Internet via certain ports. If the IP filter feature is activated, it allows/rejects the packet from a specific port of a specific IP address to be forwarded to a local specific port of a specific IP address.
Figure 4-26 IP Filter Single click New button to open the Rule Information setting page. Enter the parameters and single click Submit to save the configurations.
Figure 4-27 IP Filter Setting 4.4.7 Multinat Setting Multi-NAT can be used where you have been allocated multiple public IP addresses by your ISP. Instead of a many-to-one relationship, you can have a one-to-one relationship between a public IP address and an internal/private IP address.
addressed directly from the outside world by its fake public IP address, but still by only opening specific ports to it. Take Figure 4-28 as example, when internal IP address 192.168.1.56 accesses Internet, Internet will identify this IP address as 192.168.1.166. Internet user can access the service provided on IP address 192.168.1.56 via 192.168.1.166. Figure 4-28 Multinat Setting Single click New button to open the configuration page. Enter the internal and external IP addresses.
4.4.8 Parental Control This feature restricts the time user can access the Internet. Single click New from Parental Control main page and you will be directed to Figure 4-30. Select the MAC address of the computer that you want to control, enter which days of a week and what time of a day you want to control. When done, single Submit to activate the settings and the controlled days of the week and blocking time will be shown as in Figure 4-31.
Figure 4-31 Parental Control 4.4.9 Port Mapping Port mapping supports multiple ports to PVC and bridging groups. Each group will perform as an independent network. Single click Add button to activate this feature, create mapping groups of appropriate LAN and WAN interfaces. Single click Remove button to remove a group and add ungrouped interface to the default group. You can configure up to 16 entries.
z Click Add in Figure 4-32 and you are prompted to Figure 4-33. First enter the group name. Select interfaces from Available Interfaces and click “←” to add them into Grouped Interfaces. You can create new groups by repeating these steps. Please be noted that each group name should be different. Figure 4-33 Port Mapping — Add z Click Save/Apply to validate the modification. To remove a group, check the Remove box and click Remove.
4.4.10 Protocol Block This feature refuses user to access certain websites, or denies the visit from certain IP address for security or other reasons. It blocks the protocols you do not need to use. Apart from the default protocols, there is a Customer Define option for you to add more protocols that you want to block. Select the protocols that you wish to block and click Submit to save the change.

4.5.5 Configuring Advanced Figure 4-49 Wireless Setup — Advanced In most cases, HG520 works with default settings. If you are not familiar with these parameters, modification is not recommended. z AP Isolation: Prevents one wireless client communicating with another wireless client.
z Band: Another term for spectrum used to indicate a particular set of frequencies. Wireless networking protocols work in either 2.4GHz (802.11b/g) or the 5 GHz band (802.11a). z Channel: Select the appropriate channel from the provided list. All devices in your wireless network must use the same channel in order to function correctly. It is 11 by default. z Rate: The range is 1Mbit/s–54Mbit/s. The transmission rate depends on the speed of your wireless network.
z RTS Threshold: It is 2347 by default. The range is 0–2347 bytes. If there is inconsistent data flow, you can make slight adjustment of this value. If the network packet is smaller than the RTS threshold, RTS/CTS will not be enabled. HG520 sends Request to Send (RTS) to a particular receiving station and negotiates the transmission of data frame. After receiving an RTS, the wireless station responds with a Clear to Send (CTS) frame to acknowledge the transmission. Then the transmission begins.
Select 54g LRS if you are not familiar with 802.11b equipment. z 54g protection: In Auto mode, HG520 can improve 802.11g performance in 802.11g/802.11b mixed network through RTS/CTS. The off protection mode can maximize 802.11g throughput in most cases. z Regulatory Mode: Include 802.11d and 802.11h. 802.11d is a roaming standard that decide what frequency should be used for data transmission in different countries to ensure the correct transmission. 802.11h is the evolution of 802.
4.5.6 Quality of Service over the 802.11 Interface QoS manages time-sensitive multimedia and voice application traffic to ensure that this traffic receives higher priority, greater bandwidth, and less delay than best-effort data traffic. WLANs are now used to transport high-bandwidth, intensive data applications in conjunction with time-sensitive multimedia applications. This requirement has led to the necessity for wireless QoS. Configure wireless QoS function in Figure 4-50.
2) Select the Wireless Transmit Priority from the drop-down menu according to your demand. For example, you can select Video Priority which guarantees the transmission speed and quality of image if you are using HG520 for video conferencing. 3) Select Protocol. 4) Enter Source and Destination IP Address and Subnet Mask, UDP/TCP Source and Destination Port. 5) When you are done, single click Save/Apply to save the change.
