Configuring Network

Overview

1 Overview
The Network module provides basic router functions, including WAN connection, DHCP service, VLAN, IPTV service and more.
1.1 Supported Features
WAN The router can provide a maximum of four WAN ports. Each WAN port has its own internet connection, providing link backup and load balancing.
LAN For LAN configuration, you can configure the LAN IP address and DHCP (Dynamic Host Configuration Protocol) server. With its DHCP server enabled, the router can automatically assign IP addresses to hosts in the LAN.
IPTV IPTV services is based on the Internet protocol, rather than through traditional satellite signal or cable transmission. The router supports three kinds of IPTV configuration according to your ISP:  IPTV based on IGMP.  IPTV in Bridge mode.  IPTV in Custom mode.
MAC You can change the default MAC address of the WAN port or LAN port according to your needs.
Switch The router supports some basic switch port management functions, like Port Mirror, Rate Control, Flow Control and Port Negotiation, to help you to monitor the traffic and manage the network effectively.
VLAN The router supports 802.1Q VLAN, which can divide the LAN into multiple VLANs, helping to manage the network more effectively.
IPv6 You can set up an IPv6 internet connection if your ISP provides IPv6 service.

Note: · When a WAN port is added, a port-related tab is automatically added; when a WAN port is de-
leted, the port-related tab is automatically deleted.
· The router will reboot after switching the WAN mode.

2.2 Configuring the WAN Connection
The router supports six connection types: Static IP, Dynamic IP, PPPoE, L2TP, PPTP and BigPond Cable, you can choose one according to the service provided by your ISP.

User Guide 13

Configuring Network

WAN Configuration

Static IP: If your ISP provides you with a fixed IP address and the corresponding parameters, choose Static IP. Dynamic IP: If your ISP automatically assigns the IP address and the corresponding parameters, choose Dynamic IP. PPPoE: If your ISP provides you with a PPPoE account, choose PPPoE. L2TP: If your ISP provides you with an L2TP account, choose L2TP. PPTP: If your ISP provides you with a PPTP account, choose PPTP. BigPond Cable: If your ISP provides you with a BigPond Cable account, choose BigPond Cable. BigPond Cable is only available for Australian users.
 Configuring the Dynamic IP Choose the menu Network > WAN > WAN to load the following page.
Figure 2-2Configuring the Dynamic IP

In the Connection Configuration section, select the connection type as Dynamic IP. Enter the corresponding parameters and click Save.

Connection Type

Choose the connection type as Dynamic IP if your ISP automatically assigns the IP address.

Host Name

Optional. Enter a name for the router. It is null by default.

Upstream Bandwidth

Specify the upstream bandwidth of the WAN port. The value configured here is the upper limit of the "Maximum Upstream Bandwidth" on Transmission > Bandwidth Control > Bandwidth Control page, to make "Bandwidth Control" take effect, please ensure this parameter is set correctly.

Downstream Bandwidth

Specify the downstream bandwidth of the WAN port. The value configured here is the lower limit of the "Maximum Downstream Bandwidth" on Transmission > Bandwidth Control > Bandwidth Control page, to make "Bandwidth Control" take effect, please ensure this parameter is set correctly.

Configuring Network

WAN Configuration

MTU
Primary/ Secondary DNS VLAN
Get IP using Unicast DHCP Connect/ Disconnect

Specify the MTU (Maximum Transmission Unit) of the WAN port.
MTU is the maximum data unit transmitted in the physical network. When Dynamic IP is selected, MTU can be set in the range of 576-1500 bytes. The default value is 1500.
Optional. Enter the IP address of the DNS server provided by your ISP.
Add the WAN port to a VLAN. Generally, you don't need to manually configure it unless required by your ISP.
By default, the WAN port is automatically assigned to a VLAN, and the egress rule of the VLAN is UNTAG, so the packets are transmitted by the WAN port without VLAN tags. If you want the WAN port to transmit packets with VLAN tag, you need to create the corresponding VLAN first and configure its egress rule as TAG, then manually add the WAN port to that VLAN. To create VLANs, go to Network > VLAN > VLAN.
Note: When using the IPTV function, either in Bridge mode or Custom mode, the router will automatically create corresponding VLANs after you finished the configuration, and add port 1 (WAN 1) to the VLANs. Users cannot then manually select the VLAN that WAN 1 belongs to.
The broadcasting requirement may not be supported by a few ISPs. Select this option if you can not get the IP address from your ISP even with a normal network connection. This option is not required generally.
Click the button to active/terminate the connection.

4.1 Configuring IPTV Based on IGMP
Some ISPs provide IPTV service based on IGMP technology. In this scenario, you can just enable IGMP snooping and IGMP proxy, and connect your STB (Set-Top Box) to any LAN port of the router. The IPTV stream will then be transmitted to the corresponding LAN port. Choose the menu Network > IPTV> IPTV to load the following page.
Figure 4-1Configuring IPTV Based on IGMP

Enable IGMP Snooping and IGMP Proxy, and choose the IGMP version, then click Save.

IGMP Snooping

Check the box to enable IGMP Snooping.
Without IGMP Snooping, the router will broadcast multicast stream to all LAN ports, even though some LAN ports are not connected to any multicast member.
With IGMP Snooping enabled, the LAN ports listen IGMP packets transmitted between the router and the clients and build a multicast table. The multicast table records the multicast members and the corresponding connected LAN port. So the multicast stream will be transmitted to only the ports that connected to multicast members.

IGMP Proxy

Check the box to enable IGMP Proxy.
IGMP Proxy sends IGMP querier packets to the LAN ports to detect if there is any multicast member connected to the LAN ports.

IGMP Version

Choose the IGMP version as V2 or V3. The default is IGMP V2.

Transmission

1.1 Overview
Transmission function provides multiple traffic control measures for the network. You can configure the transmission function according to your actual needs.
1.2 Supported Features
The transmission module includes NAT, Bandwidth Control, Session Limit, Load Balancing and Routing.
NAT NAT (Network Address Translation) is the translation between private IP and public IP. NAT provides a way to allow multiple private hosts to access the public network using one public IP at the same time, which alleviates the shortage of IP addresses. Furthermore, NAT strengthens the LAN (Local Area Network) security since the address of LAN host never appears on the internet. The router supports following NAT features:
 Multi-Nets NAT Multi-Nets NAT function can help the router provide NAT translation for multiple subnets.
 One-to-One NAT One-to-One NAT creates a relationship between a private IP address and a public IP address. A device with a private IP address can be accessed through the corresponding valid public IP address.
 Virtual Servers When you build up a server in the local network and want to share it on the internet, Virtual Servers can realize the service and provide it to the internet users. At the same time Virtual Servers can keep the local network safe as other services are still invisible from the internet.
 Port Triggering Port Triggering is a feature used to dynamically forward traffic on a certain port to a specific server on the local network. When a host in the local network initiates a connection to the triggering port, all the external ports will be opened for subsequent connections. The router can record the IP address of the host, when the data from the internet returns to the

User Guide 64

Configuring Transmission

Transmission

external ports, the router can forward them to the corresponding host. Port Triggering is mainly applied to online games, VoIPs, video players and so on.
 NAT-DMZ
When a PC is set to be a DMZ (Demilitarized Zone) host in the local network, it is totally exposed to the internet, which can realize the unlimited bidirectional communication between internal hosts and external hosts. The DMZ host becomes a virtual server with all ports opened. When you are not clear about which ports to open in some special applications, such as IP camera and database software, you can set the PC to be a DMZ host.
 ALG
Some special protocols such as FTP, H.323, SIP, IPSec and PPTP will work properly only when ALG (Application Layer Gateway) service is enabled.
Bandwidth Control You can control the bandwidth by configuring bandwidth control rules for limiting various data flows. In this way, the network bandwidth can be reasonably distributed and utilized.
Session Limit The amount of TCP and UDP sessions supported by the router is finite. If some local hosts transmit too many TCP and UDP sessions to the public network, the communication quality of the other local hosts will be affected, thus it is necessary to limit the sessions of those hosts.
Load Balancing You can configure the traffic sharing mode of the WAN ports to optimize the resource utilization.
Routing You can configure policy routing rules and static routing.
Policy routing provides a more accurate way to control the routing based on the policy defined by the network administrator.
Static routing is a form of routing that is configured manually by adding non-aging entries into a routing table. The manually-configured routing information guides the router in forwarding data packets to the specific destination.

Firewall

1.1 Overview
Firewall is used to enhance the network security. It can prevent external network threats from spreading to the internal network, protect the internal hosts from ARP attacks, and control the internal users' access to the external network.
1.2 Supported Features
The Firewall module supports four functions: Anti ARP Spoofing, Attack Defense, MAC Filtering and Access Control.
Anti ARP Spoofing ARP (Address Resolution Protocol) is used to map IP addresses to the corresponding MAC addresses so that packets can be delivered to their destinations. However, since ARP is implemented with the premise that all the hosts and gateways are trusted, there are high security risks on real, complex networks. If attackers send ARP spoofing packets with false IP address-to-MAC address mapping entries, the device will update the ARP table based on the false ARP packets and record wrong mapping entries, which results in a breakdown of normal communication.
Anti ARP Spoofing can protect the network from ARP spoofing attacks. It works based on the IP-MAC Binding entries. These entries record the correct one-to-one relationships between IP addresses and MAC addresses. When receiving an ARP packet, the router checks whether it matches any of the IP-MAC Binding entries. If not, the router will ignore the ARP packets. In this way, the router maintains the correct ARP table.
In addition, the router provides the following two sub functions:
 Permitting the packets matching the IP-MAC Binding entries only and discarding other packets.
 Sending GARP packets to the hosts when it detects ARP attacks. The GARP packets can inform hosts of the correct ARP table, preventing their ARP tables from being falsified by ARP spoofing packets.
Attack Defense Attacks on a network device can cause device or network paralysis. With the Attack Defense feature, the router can identify and discard various attack packets which are sent to the CPU, and limit the packet receiving rate. In this way, the router can protect itself and the connected network against malicious attacks.
User Guide 91

Configuring Firewall

Firewall

The router provides two types of Attack Defense: Flood Defense and Packet Anomaly Defense. Flood Defense limits the receiving rate of the specific types of packets, and Packet Anomaly Defense discards the illegal packets directly.
MAC Filtering
MAC Filtering can flexibly control the access to the network of the specific hosts. You can simply add the MAC addresses of the hosts to the MAC Filtering List and specify the filtering rule for these hosts. Two rules are provided: allow the packets with the MAC addresses in the MAC Filtering List and deny other packets, or deny the packets with the MAC addresses in the MAC Filtering List and allow other packets.
Access Control
Access Control can filter the packets passing through the router based on the Access Control rules. An Access Control rule includes a filter policy and some conditions, such as service type, receiving interface and effective time. The router will apply the filter policy to the packets matching these conditions, and thus to limit network traffic, manage network access behaviors and more.
Access Control can prevent various network attacks, such as attacks on TCP (Transmission Control Protocol) and ICMP (Internet Control Message Protocol) packets, and can also manage network access behaviors, such as controlling access to the internet.

2.1 Anti ARP Spoofing
To complete Anti ARP Spoofing configuration, there are two steps. First, add IP-MAC Binding entries to the IP-MAC Binding List. Then enable Anti ARP Spoofing for these entries.
Note:
In case Anti ARP Spoofing causes access problems to the currently connected devices, we recommend that you add and verify the IP-MAC Binding entries first before enabling Anti ARP Spoofing.
2.1.1 Adding IP-MAC Binding Entries
You can add IP-MAC Binding entries in two ways: manually and via ARP scanning.
 Adding IP-MAC Binding Entries Manually You can manually bind the IP address and MAC address together on the condition that you have got the related information of the hosts on the network.
 Adding IP-MAC Binding Entries via ARP Scanning With ARP Scanning, the router sends the ARP request packets with the specific IP field to the hosts. Upon receiving the ARP reply packet, the router can get the IP address, MAC address and connected interface of the host. The following sections introduce these two methods in detail.

3.1.2 Configuration Scheme

The attacker can launch three types of ARP attacks: cheating gateway, imitating gateway and cheating terminal hosts. The following section introduces the three ARP attacks and the corresponding solutions.

 Cheating Gateway Cheating gateway attack is aimed at the router.

User Guide 103

Configuring Firewall

Configuration Examples

The attacker pretends to be legal terminal hosts and sends fake ARP packets to the router, cheating the router into recording wrong ARP maps of the hosts. As a result, packets from the gateway cannot be correctly sent to the hosts. To protect the router from this kind of attack, you can configure Anti ARP Spoofing on the router.
 Imitating Gateway and Cheating Hosts
These two attacks are aimed at the terminal hosts.
Imitating Gateway means that the attacker imitates the gateway and sends fake ARP packets to the hosts. As a result, the hosts record wrong ARP map of the gateway and cannot send packets to the router correctly.
Cheating Hosts means that the attacker pretends to be a legal host and sends fake ARP packets to other hosts. As a result, the cheated hosts record an incorrect ARP map of the legal host and cannot send packets to legal host correctly.
To protect the hosts from the attacks above, it is recommend to take both of the precautions below.
· Configure the firewall feature on the hosts.
· Configure the router to send GARP packets to the hosts when the router detects ARP attacks. The GARP packets will inform the hosts of the correct ARP maps, and the wrong ARP maps in the hosts will be replaced by the correct ones.
In conclusion, to protect the network from ARP attacks, we should make sure both the router and the hosts are configured with the relevant ARP defense features. Here we introduce how to configure Anti ARP Spoofing on the router. There are mainly three steps: 1) Get the IP and MAC addresses of the legal hosts and bind them to the IP-MAC Binding
list. 2) Enable Anti ARP Spoofing. 3) Configure the router to send GARP packets when ARP attacks are detected.

1.1 Overview
VPN (Virtual Private Network) provides a means for secure communication between remote computers across a public wide area network (WAN), such as the internet. Virtual indicates the VPN connection is based on the logical end-to-end connection instead of the physical end-to-end connection. Private indicates users can establish the VPN connection according to their requirements and only specific users are allowed to use the VPN connection.
The core of VPN is to realize tunnel communication, which fulfills the task of data encapsulation, data transmission and data decompression via the tunneling protocol. Common tunneling protocols are Layer 2 tunneling protocol and Layer 3 tunneling protocol.

Remote Client

Gateway (Client)

Internet VPN Tunnel

Gateway (Server)

Enterprise Server

1.2 Supported Features
The router supports Layer 2 tunneling protocol (PPTP, L2TP) and Layer 3 tunneling protocol (IPSec).
PPTP PPTP (Point-to-Point Tunneling Protocol) is a network protocol that enables the secure transfer of data from a remote client to a private enterprise server by creating a VPN across TCP/IP-based data networks. PPTP supports on-demand, multiprotocol, virtual private networking over public networks, such as the internet.
L2TP L2TP (Layer 2 Tunneling Protocol) provides a way for a dialup user to make a virtual Pointto-Point Protocol (PPP) connection to an L2TP network server (LNS), which can be a security gateway. L2TP sends PPP frames through a tunnel between an L2TP access concentrator (LAC) and the LNS. Because of the lack of confidentiality inherent in the L2TP protocol, it is often implemented along with IPSec.

IPSec
IPSec (IP Security) can provide security services such as data confidentiality, data integrity and data authentication at the IP layer. IPSec uses IKE (Internet Key Exchange) to handle negotiation of protocols and algorithms based on the user-specified policy, and to generate the encryption and authentication keys to be used by IPSec. IPSec can be used to protect one or more paths between a pair of hosts, between a pair of security gateways, or between a security gateway and a host. The security gateway refers to a device which implements IPSec protocol. For example, a router or a firewall implementing IPSec is a security gateway.

Configuring Authentication

Overview

1 Overview
Portal authentication, also known as Web authentication, is usually deployed in a guestaccess network (like a hotel or a coffee shop) to control the client's internet access. In portal authentication, all the client's HTTP requests will be redirected to an authentication page first. The client needs to enter the account information on the page to authenticate, then can visit the internet after the authentication succeeded.
1.1 Typical Topology
The typical topology of portal authentication is shown as below:
Figure 1-1Topology of Portal Authentication

Web Server

Client

Access Device

Authentication Server

 Client The end device that needs to be authenticated before permitted to access the internet.
 Access Device The device that supports portal authentication. In this configuration guide, it means the router. The Access Device helps to: redirect all HTTP requests to the Web Server before authenticated; interact with the Authentication Server to authenticate the client during the authentication process; permit users to access the internet after the authentication succeeded.
 Web Server The web server responds to client's HTTP requests, and returns an authentication login page.
 Authentication Server The authentication server records the information of the user's account, and interacts with the access device to authenticate clients.

1) The client is connected to the router but not authenticated, and starts to visit the internet through HTTP;
2) The router redirects the client's HTTP request to the web server; 3) The client visits the web server; 4) The Web server returns the authentication login page to the client; 5) The client enters the username and password on the authentication login page; 6) The router forwards the username and password to the authentication server; 7) The authentication server returns the authentication result to the router; 8) The router replies to the client with the authentication result; 9) The client visits the internet after the authentication succeeded.
1.3 Supported Features
To configure portal authentication, you need to configure both the web server and the authentication server. The web server provides the authentication page for login; the authentication server records the account information and authenticates the clients.

User Guide 163

Configuring Authentication

Overview

1.3.1 Supported Web Server
The router has a built-in web server and also supports external web server. You can configure the authentication page either using the built-in server or the external server.
Custom Page You can use the built-in web server and customize the authentication page on your router.
External Links You can specify the external web server and configure the authentication page on the external web server.
1.3.2 Supported Authentication Server
The router provides three types of portal authentication:
RADIUS Authentication In RADIUS authentication, you can specify an external RADIUS server as the authentication server. The user's account information are recorded in the RADIUS server.
Local Authentication If you don't have an additional RADIUS server, you can choose local authentication. In local authentication, the router uses the built-in authentication server to authenticate. The builtin authentication server can record at most 500 local user accounts, and each account is can be used for at most 1024 clients to authenticate.
Onekey Online In Onekey Online Authentication, users can access the network without entering any account information.
1.3.3 Guest Resources
Guest Resources is used to provide free resources for users before they pass the portal authentication.

Services

1.1 Overview
The Services module incorporates two functions, Dynamic DNS (DDNS) and UPnP (Universal Plug and Play) to provide convenient network services.
1.2 Support Features
Dynamic DNS Nowadays, network protocols such as PPPoE and DHCP are widely employed by ISPs to assign public IP addresses to users. The use of these protocols can cause the user's public IP address to change dynamically. DDNS is an internet service that ensures a fixed domain name can be used to access a network with a varying public IP address. This means the user's network can be more easily accessed by internet hosts.
UPnP With the development of networking and advanced computing techniques, greater numbers of devices feature in networks. UPnP is designed to solve the problem of communication between these network devices. UPnP function allows devices dynamically discover and communicate with each other without additional configurations. For example, it allows the download of P2P software without opening ports.

Figure 4-1Network Topology

Host A

Router

Internet

Internet Host

4.2 Configuration Scheme
For security management, the internet hosts attempting to manage the router must be permitted by the router. Remote Management is used to manage the IP addresses of these hosts.
Because the user uses PPPoE to access to the network, the public IP address of the router may be changed each time the dial-up connection is established. When the public IP address of the router changes, DDNS service ensures the DNS server rebinds the current domain name to the new IP address. This means the user can always reach the router using the same domain name, even if the public IP address has been changed.
4.3 Configuration Procedure

4.3.1 Specifying the IP Address of the Host
Before configuring DDNS, it is required to specify the IP address of the internet host for remote management. For details, go to System Tools > Admin Setup > Remote Management page.
