Rental Housing Broadband Network Solutions

These two days brother called me he rented the house inside the network problem, because has been using campus network did not contact broadband, make still confused, but fortunately finally solve, otherwise really embarrassed to say that they are learning communication.

Return to Hangzhou after Spring Festival, brother feedback Broadband connection: Error code 678, the remote host is unresponsive.

Troubleshooting One: Can enter the system, and system-independent; teach elder brother use cmd, after ipconfig confirm, IP address is normal, ping 127.0.0.1 normal, Nic is normal.

Troubleshooting two: Network card lamp Status: Yellow light is long and bright, green is not bright. Yellow light long bright instructions to establish a normal link, green light (the internet is said to be in the 10M bandwidth under the green light is not bright, only in the 100M or Gigabit Ethernet conditions will be lit, after viewing their own computer indeed). Initially determine the network link is normal.

Troubleshooting three: Let brother move host to next door rent Hakka link. After trying to be able to connect normally, the problem is in the network cable or switch-ADSL dial end.

Troubleshooting Quad: 10,000th, ask for help querying for problems. The result of his reply is to say that the arrears, giant pits, next door can be on, and certainly no arrears.

Troubleshooting Five: The suspicion is the network cable socket loose, at the landlord end and their own computer side are excluded, no effect. After the landlord changed the network cable, changed a socket, finally normal.

I was very suspicious of what my brother said, saying that all tenants use the same broadband account and password to get online after the landlord, everyone needs to dial the operation separately. I check some information on the Internet, the main implementation methods are as follows:

1. Multi-port Cat Telecom allows the existence of multiple dials, respectively, after several dial-up to achieve Internet access.

2. Pppoe-server. Google's solution is as follows ( go )

This article is based on HiPER 510/520 the REOs v12pro Version (V12 Professional Edition), HiPER 841/840d the REOs V12 version. Preface:Rental housing in the provision of simple and convenient living places, usually also provide a paid network services. This article takes the rental housing environment as the object, introduces the common configuration scheme of the rental Housing network gateway in detail. Network analysis:For the rental housing network, the features commonly used in Gateway devices are: Configuring the Internet, load balancing, pppoe-server, bandwidth management. 1. Configure the Internet rental housing generally applied for telecommunications/Unicom broadband, using PPPoE dial mode connection is more common. 2. Load balancing for multiple Internet connections from the same carrier, the bandwidth overlay effect can be achieved through this function, making full use of the Internet resources. 3. Pppoe-server This feature has been implanted into the Hayter gateway device, which allows the landlord to open an online account and password for the tenant as the operator, so that the residents can dial the Internet via a broadband connection on the computer. And each household's computer between the ARP spoofing attack (ARP spoofing attack, a common network attack means, can make the attack of the computer often appear online drop, slow speed and other symptoms) will be completely resolved. 4. Bandwidth Management The network resources (bandwidth) from the operator application is valuable, in the rental housing network, how these valuable resources (bandwidth) will be allocated to the Internet of computers, so that each computer on the Internet each line of the road, independent of the allocation of reasonable bandwidth management strategy. network topology diagram: Configuration scenarios: This configuration scenario takes HiPER 510/520 the REOs v12pro Version (V12 Professional Edition), HiPER 841/840d the REOs V12 The version is the baseline for illustration. First, Configure the Internet  Rental housing generally applied for telecommunications/Unicom broadband, the use of PPPoE dial-up connection is more common. In the WAN Port Configuration page, basic configuration, WebUI, select WAN1 port for configuration, connection type select "PPPoE Internet", uplink bandwidth and downlink bandwidth according to the actual situation of the Internet line (in general, the uplink bandwidth of the ADSL access is 512K, If this value is not clear, can consult the operator), the operator chooses "other lines", the user name and password to fill in the operator opened the Internet account and password, dialing mode select "Normal mode", the DNS server configuration Select "Automatic Allocation." If you access multiple Internet lines at the same time, you must configure the WAN1 port before configuring the other WAN ports. Second, Load Balancing  It is recommended to use load Balancing mode when the Internet line is connected to multiple lines and both are from the same carrier. As a result, bandwidth can be superimposed, and network resources can be fully utilized. The configuration steps are as follows. 1. In the Global Settings page, line combination, basic configuration, WebUI, set the allocation rule to "NAT session" and set the combination to "all line load balancing". 2. In the Combination information page, basic configuration----WebUI, the weight of each internet line is individually set. For example, there are currently 4 Internet lines, each line of bandwidth is 12M, so the weight of the 4 Internet lines can be set to the same value (the default is 1, without modification); If 4 internet lines are 12M, 8M, 8M and 4M, the weights of 4 Internet lines can be modified to 3, 2, 2 and 1.   Third, Pppoe-server  Pppoe-server function is advantageous for renting landlord control network, prevent unauthorized computer to enter the network, and Pppoe-server can completely solve the problem of ARP spoofing in LAN, and prevent the problems such as frequent computer drop or Internet speed card caused by ARP spoofing. The configuration steps are as follows. 1.         on the Global Configuration page, PPPoE-----WebUI, enable the PPPoE server to tick, Start IP address remains the default, the total number of addresses according to the actual number of households using the network set, the primary and standby DNS server set up the Internet line is the operator designated DNS server, if not clear, you can consult the operator.  2.         on the PPPoE Account Configuration page, PPPoE-i-WebUI, For the Internet tenants to set up their online account and password. In the two gateway devices of the HiPER 841 and HiPER 840D, there is also a separate bandwidth for the online account (HiPER 510 and HiPER 520 do not support this feature, for bandwidth management purposes see below). In the ADSL Internet line, the total upstream bandwidth of a single Internet line is generally only 512Kbit, so in the setting based on the PPPoE account speed limit function, should pay attention to control the uplink bandwidth. Tested: Upstream bandwidth set 80kbit/s, downlink bandwidth setting 2mbit/s (also required to WebUI, bandwidth management-speed Global configuration page, the Enable Speed limit feature is selected as "Enable fine speed limit" mode), Fully able to access video websites (such as Youku, potatoes, etc.) on the Internet through this account to watch online videos, movies, TV dramas and other applications.  3.         Household computer Internet access in the form of broadband connection, enter the landlord on the gateway for its open PPPoE account and password, dial-up connection to the Internet.  4.         to prohibit Internet access for households that do not have an online account, you can set up an Internet control function. On the Internet Control page, PPPoE-----WebUI, enable "Allow PPPoE users to surf the internet Only", and network security at WebUI-> Address group configuration, Address Group configuration page, set up an IP address segment that is not subject to this control and refer to the exception address group.   Four, Bandwidth Management  In the public network, the bandwidth of the Internet line is a valuable resource, should be managed, so that every computer reasonable demand for Internet access is met. Prevent the entire network from being dragged down by the uncontrolled use of bandwidth by individual computers using peer-to-peer downloads (such as BT, E-Asses) or video (such as PPS, PPTV). Do bandwidth management to address these issues. Bandwidth management is divided into two modes: fine speed limit and intelligent elastic speed limit, in the rental housing network, the general use of fine speed limit mode, the following on how to set the fine speed limit function to do a detailed introduction. 1. In the speed-limit global configuration page, bandwidth management---speed global configuration, WebUI, enable the speed limit feature to select the "Enable granular speed limit" mode, which fills in the total number of Internet PCs and the upstream and downstream bandwidth of each internet line. 2. In the speed-limiting rules configuration page, bandwidth management, WebUI, select "All addresses" from the source address, select "All addresses" for the destination address, ensure that the uplink and the maximum downlink are set to NULL, the maximum upstream and the largest downstream depending on the bandwidth situation and the number of machines, if the total Bandwidth for the total belt machine is not sufficient, can refer to the maximum downstream setting between 1.5m-2mbit/s, the maximum upstream setting between 60-80kbit/s, if the total bandwidth for the total belt machine is more sufficient, can refer to the maximum downstream settings between 2m-3mbit/s, The maximum upstream setting is between 80k-100kbit/s, set up can use the computer to do open Web page, visit video website to watch movies and TV series and other operation test effect, and make speed limit strategy debugging according to test effect.      Note: For HiPER 840D, in a rental housing environment, it is generally not necessary to enable the features in the Application Priority Protection feature (in the Application Priority Protection page, WebUI-I, bandwidth management). Thanks to the original author of the method of sharing, harvest a lot, I hope that they will encounter and solve problems in a timely manner to form a solution, record down, develop a good habit of sharing life.
