1.4 Work Mode
The device can work in router mode and AC mode. The system menu pages and configuration function scope vary depending on the work mode. By default, the EG router works in router mode. To modify the work mode, see Section 3.1 Switching the Work Mode.
1.4.1 Router Mode
The device supports routing functions such as route-based forwarding and network address translation (NAT), VPN, and behavior management. It can allocate addresses to downlink devices, forward network data based on routes, and perform NAT operations. In the router mode, the device can access the network through Point-to-Point Protocol over Ethernet (PPPoE) dialing, dynamic IP address, and static IP address. It can also directly connect to a fiber-to- the-home (FTTH) network cable or an uplink device to provide network access and manage downlink devices.
1.4.2 AC Mode
The device supports Layer 2 forwarding only. The device does not provide the routing and Dynamic Host Configuration Protocol (DHCP) server functions. By default, the WAN port obtains IP addresses through DHCP. The AC mode is applicable to the scenario where the network is working normally. In AC mode, the device serves as the management controller to access the network in bypass mode and manage the AP.
1.5 Configuration Wizard (Router Mode)
1.5.1 Getting Started
(1) Power on the device. Connect the WAN port of the device to an uplink device using an Ethernet cable, or connect the device to the optical modem directly.
(2) Configure the Internet connection type according to requirements of the local Internet Service Provider (ISP). Otherwise, the Internet access may fail due to improper configuration. You are advised to contact your local ISP to confirm the Internet connection type: Figure out whether the Internet connection type is PPPoE, DHCP mode, or static IP address mode. In the PPPoE mode, a username, a password, and possibly a service name are needed. In the static IP address mode, an IP address, a subnet mask, a gateway, and a DNS server need to be configured.

Network-Wide Monitoring

When multiple links are available, some traffic is forwarded along the link selected based on the address library and the remaining traffic is distributed to other links in load balancing mode.

Table 3-1 Load balancing modes

Load Balancing Mode

Description

Balanced

The traffic will be distributed across multiple links according to the weight of each WAN port. Larger traffic will be distributed to the WAN port with a higher weight.
When you select this mode, you must specify the weight of each WAN port.
For example, if the weight of WAN and WAN 1 ports is set to 3 and 2 respectively, then, 60% of the total traffic will be routed over WAN and 40% over WAN 1.

Primary & Secondary

All traffic is routed over the primary interface. Once the primary interface fails, traffic will be switched over to the secondary interface.
If there are multiple primary or secondary interfaces, the weight of these interfaces must be set. (See balanced mode.)

The system supports IPv4 and IPv6 multi-link load balancing. IPv4 multi-link load balancing is enabled by default, while IPv6 multi-link load balancing needs to be enabled manually.
1. Configuring IPv4 Multi-Link Balancing

(1) Select a load balancing mode from the Load Mode drop-down list. (2) Select a loading balancing policy from the Load Balancing Policy drop-down list.

Description

Network-Wide Monitoring

Based on Connections

After you enable this policy, the traffic is routed over multiple links based on the links. Packets with the same source IP address, destination IP address, source port, destination port, and protocol are routed over the same link.

Based on Src IP Address

After you enable this policy, the traffic is routed over multiple links based on the source IP address. The traffic from the same user (same source IP address) will be routed to the same interface. This policy prevents traffic from the same user from being routed to different links, lowering the risks of network access exceptions.

Based on Src and Dest IP Address

After you enable this policy, the traffic is routed over multiple links based on the source IP address and destination. The traffic of the same source IP address and destination IP address will be routed to the same interface.

Smart Load Balancing

After you enable this feature, the traffic is routed over multiple links based on the link bandwidth, the actual loads of the links, application recognition and traffic prediction.

(2) Set the uplink and downlink bandwidths or the weight for each WAN port. When the load balancing policy is set to Based on Connections, Based on Src IP Address, or Based on
Src and Dest IP Address, a weight must be set for each WAN port.
Note The higher the value of the weight, the more traffic is directed to the WAN port.

3.5 Configuring VLAN
3.5.1 VLAN Overview
Virtual Local Area Network (VLAN) is a communication technology that divides a physical LAN into multiple logical broadcast domains. Each VLAN has independent broadcast domains. Hosts in the same VLAN can directly communicate with each other, while hosts in different VLANs cannot as they are isolated at Layer 2. Compared with traditional Ethernet, VLAN has the following advantages: Control broadcast storms: Broadcast packets can only be forwarded inside a VLAN. This saves bandwidth as
the performance of a VLAN is not affected by broadcast storms of other VLANs.
49

Web-based Configuration Guide

Network-Wide Monitoring

Enhance LAN security: As a VLAN is divided into multiple broadcast domains, packets of different VLANs in a LAN are isolated. Different VLAN users cannot directly communicate, enhancing network security.
Simplify network management: The VLAN technology can be used to divide the same physical network into different logical networks. When the network topology changes, you only need to modify the VLAN configuration, simplifying network management.

You also need to specify the start address for IP address allocation by the DHCP server, the number of IP addresses that can be allocated, and the address lease. You can also configure DHCP Options. For details, see Section 3.7.3 Configuring the DHCP Server.

Caution The VLAN configuration is associated with the uplink configuration. Exercise caution when you perform this operation.
3.5.3 Configuring a Port VLAN
Choose Local Device > Network > Port VLAN. This page displays the VLAN division of the current port. Create VLANs on the LAN Settings page and then configure the port based on the VLANs on this page. For details, see Section 3.4.2 Creating a VLAN. Click the check box under a port and select the relationship between VLAN and port from the drop-down list box. UNTAG: Configure the VLAN as the native VLAN of the port. When the port receives packets from the specified
VLAN, the port removes the VLAN ID before forwarding the packets. When the port receives packets without a VLAN ID, the port adds this VLAN ID to the packets before forwarding them. You can set only one VLAN of the port to UNTAG. TAG: Configure the port to allow packets with this VLAN ID to pass. This VLAN is not the native VLAN. When the port receives packets from the specified VLAN, it forwards the packets with the original VLAN ID. Not Join: Configure the port to deny packets with this VLAN ID to pass. For example, if you set VLAN 10 and VLAN 20 to Not Join for port 2, port 2 will not receive packets from VLAN 10 and VLAN 20.

3.8 Configuring IPv6

3.8.1 IPv6 Overview
Internet Protocol Version 6 (IPv6) is the next-generation IP protocol designed by Internet Engineering Task Force (IETF) to substitute IPv4. It is used to compensate insufficient IPv4 network addresses.
3.8.2 IPv6 Basics

1. IPv6 Address Format
IPv6 extends 32-bit IPv4 address into 128 bits, providing wider address space than IPv4. The basic format of an IPv6 address is X:X:X:X:X:X:X:X. It is represented as eight groups of four hexadecimal digits (0-9, A-F), each group representing16 bits. The groups are separated by colons (:). In this format, each X represents a group of four hexadecimal digits. Samples of IPv6 addresses are 2001:ABCD:1234:5678:AAAA:BBBB:1200:2100, 800:0:0:0:0:0:0:1, and 1080:0:0:0:8:800:200C:417A. The digit 0 in an IPv6 address can be suppressed as follows: Leading zeros in each 16-bit field are suppressed. For example, 2001:00CD:0034:0078:000A:000B:1200:2100
can be suppressed to 2001:CD:34:78:A:B:1200:2100. The long sequence of consecutive all-zero fields in some IPv6 addresses can be replaced with two colons (::).
For example, 800:0:0:0:0:0:0:1 can be represented as 800::1. The two colons (::) can be used only when all the 16 bits in a group are 0s, and it can appear only once in an IPv6 address.
2. IPv6 Prefix
IPv6 addresses are typically composed of two logical parts: Network prefix: n bits, corresponding to the network ID in IPv4 addresses interface ID: (128 ­ n) bits, corresponding to the host ID in IPv4 addresses A slash (/) is used to separate the length of network prefix from an IPv6 address. For example, 12AB::CD30:0:0:0:0/60 indicates that the 60-bit network prefix in the address is used for route selection. IPv6 prefixes can be obtained from the IPv6 DHCP server, along with IPv6 addresses. A downlink DHCP server can also automatically obtain IPv6 prefixes from its uplink DHCP server.
3. Special IPv6 Addresses
There are some special IPv6 addresses: fe80::/8: loopback address, similar to the IPv4 address 169.254.0.0/16 fc00::/7: local address, similar to IPv4 addresses 10.0.0.0/8, 172.16.0.0/16, and 192.168.0.0/16 ff00::/12: multicast address, similar to the IPv4 address 224.0.0.0/8
4. NAT66
IPv6-to-IPv6 Network Address Translation (NAT66) is a process of converting the IPv6 address in the IPv6 data packet header into another IPv6 address. NAT66 can be implemented by converting the prefix in an IPv6 address

55

Web-based Configuration Guide

Network-Wide Monitoring

in an IPv6 data packet header into another IPv6 address prefix. NAT66 enables mutual access between an internal network and an external public network.
3.8.3 IPv6 Address Allocation Modes
Manual configuration: IPv6 addresses, prefixes, and other network parameters are configured manually. Stateless Address Autoconfiguration (SLAAC): The link-local address is generated based on the interface ID,
and the lPv6 address is automatically allocated based on the prefix information in the Router Advertisement (RA) packet. Stateful address allocation (DHCPv6): Two DHCPv6 allocation methods are as follows: Automatic DHCPv6 allocation: The DHCPv6 server automatically allocates IPv6 addresses, prefixes, and
other network parameters. Automatic allocation of DHCPv6 Prefix Delegations (PDs): The lower-layer network device submits a prefix
allocation application to the upper-layer network device. The upper-layer network device allocates an appropriate address prefix to the lower-layer device. The lower-layer device further divides the obtained prefix (usually less than 64 bits) into 64-bit prefixed subnet segments and advertises the address prefixes to the user link directly connected to the IPv6 host through the RA packet, implementing automatic address configuration for hosts.
3.8.4 Enabling the IPv6 Function

Choose Local Device > Network > IPv6 Address. Turn on Enable to enable the IPv6 function.

3.8.5 Configuring an IPv6 Address for the WAN Port
Choose Local Device > Network> IPv6 Address > WAN Settings. After you enable the IPv6 function, you can set related parameters on the WAN Settings tab. The number of WAN_V6 tabs indicates the number of WAN ports on the current device.

3.8.6 Configuring an IPv6 Address for the LAN Port
Choose Local Device > Network > IPv6 Address > LAN Settings. When the device accesses the Internet through DHCP, it can obtain LAN port IPv6 addresses from the uplink device and allocate IPv6 addresses to the clients in the LAN based on the IPv6 address prefix. If the uplink device cannot allocate an IPv6 address prefix to the device, you need to manually configure an IPv6 address prefix for the LAN port and enable the NAT66 function to allocate IPv6 addresses to the clients in the LAN. For details, see Section 3.6.5 Configuring an IPv6 Address for the WAN Port.

Click Edit next to the default VLAN, and set IPv6 Address/Prefix Length to a local address with no more than 64 bits. This address is also used as the IPv6 address prefix. You can use either of the following methods to allocate IPv6 addresses to clients: Auto: Allocate IPv6 addresses to clients in DHCPv6 or SLAAC mode.
58

Web-based Configuration Guide

3.9 Configuring a DHCP Server

3.9.1 DHCP Server Overview
After the DHCP server function is enabled in the LAN, the device can automatically deliver IP addresses to clients, so that clients connected to the LAN ports of the device or connected to Wi-Fi can access the Internet using the obtained addresses. See Section 3.6.6 Configuring an IPv6 Address for the LAN Port for more information about the DHCPv6 server function.
3.9.2 Address Allocation Mechanism
The DHCP server allocates an IP address to a client in the following way: (1) When the device receives an IP address request from a DHCP client, the device searches the DHCP static
address allocation list. If the MAC address of the DHCP client is in the DHCP static address allocation list, the device allocates the corresponding IP address to the DHCP client. (2) If the MAC address of the DHCP client is not in the DHCP static address allocation list or the IP address that the DHCP client applies is not in the same network segment as the LAN port IP address, the device selects an IP address not used from the address pool and allocates the address to the DHCP client. (3) If no IP address in the address pool is allocable, the client will fail to obtain an IP address.
3.9.3 Configuring the DHCP Server

1. Configuring Basic Parameters
Choose Local Device > Network > LAN > LAN Settings. DHCP Server: The DHCP server function is enabled by default in the router mode. You are advised to enable the function if the device is used as the sole router in the network. When multiple routers are connected to the upperlayer device through LAN ports, disable this function.
Caution If the DHCP server function is disabled on all devices in the network, clients cannot automatically obtain IP addresses. You need to enable the DHCP server function on one device or manually configure a static IP address for each client for Internet access.
Start: Enter the start IP address of the DHCP address pool. A client obtains an IP address from the address pool. If all the addresses in the address pool are used up, no IP address can be obtained from the address pool. IP Count: Enter the number of IP addresses in the address pool. Lease Time(Min): Enter the address lease term. When a client is connected, the leased IP address is automatically renewed. If a leased IP address is not renewed due to client disconnection or network instability, the IP address will be reclaimed after the lease term expires. After the client connection is restored, the client can request an IP address again. The default lease term is 30 minutes.

Parameter

Description

Dest IP Address

Specify the destination network to which the data packet is to be sent. The device matches the data packet based on the destination address and subnet mask.

Subnet Mask

Specify the subnet mask of the destination network. The device matches the data packet based on the destination address and subnet mask.

Outbound Interface

Specify the interface that forwards the data packet.

Next Hop

Specify the IP address of the next hop in the route for the data packet. If the outbound interface accesses the Internet through PPPoE dialing, you do not need to configure the next-hop address.

After a static route is created, you can find the relevant route configuration and reachability status in the static route list. The Reachable parameter specifies whether the next hop is reachable, based on which you can determine whether the route takes effect. If the value is No, check whether the outbound interface in the current route can ping the next-hop address.

3.10.2 Configuring PBR

Policy-based routing (PBR) is a mechanism for routing and forwarding based on user-specified policies. When a router forwards data packets, it filters the packets according to the configured rules, and then forwards the matched packets according to the specified forwarding policy. The PBR feature enables the device to formulate rules according to specific fields (source or destination IP address and protocol type) in the data packets, and forward the data packets from a specific interface.
In a multi-line scenario, if the device is connected to the Internet and the internal network through different lines, the traffic will be evenly routed over the lines if no routing settings are available. In this case, access data to the internal network may be sent to the external network, or access data to the external network may be sent to the internal network, resulting in network exceptions. To prevent these exceptions, you need to configure PBR to control data isolation and forwarding on the internal and external networks.
The device can forward data packets using either of the following three policies: PBR, address-based routing, and static routing. When all the policies exist, PBR, static routing, and address-based routing have descending order in priority. For details on address-based routing, see Section 3.2.6 Configuring the Multi-Line Load Balancing Mode.

3.14 Port Mapping
3.14.1 Overview

Network-Wide Monitoring

1. Port Mapping
The port mapping function can establish a mapping relationship between the IP address and port number of a WAN port and the IP address and port number of a server in the LAN, so that all access traffic to a service port of the WAN port will be redirected to the corresponding port of the specified LAN server. This function enables external users to actively access the service host in the LAN through the IP address and port number of the specified WAN port. Application scenario: Port mapping enables users to access the cameras or computers in their home network when they are in the enterprise or on a business trip.
2. NAT-DMZ
When an incoming data packet does not hit any port mapping entry, the packet is redirected to the LAN server according to the Demilitarized Zone (DMZ) rule. All data packets actively sent from the Internet to the device are forwarded to the designated DMZ host, thus realizing LAN server access of external network users. DMZ not only realizes the external network access service, but also ensures the security of other hosts in the LAN. Application scenario: Configure port mapping or DMZ when an external network user wants to access the LAN server, for example, access a server deployed in the home network when the user is in the enterprise or on a business trip.
3.14.2 Getting Started
Confirm the intranet IP address of the mapping device on the LAN and the port number used by the service. Confirm that the mapped service can be normally used on the LAN.
3.14.3 Configuration Steps
Choose Local Device > Advanced > Port Mapping > Port Mapping. Click Add. In the dialog box that appears, enter the rule name, service type, protocol type, external port/range, internal server IP address, and internal port/range. You can create a maximum of 50 port mapping rules.

Protocol

Select the transmission layer protocol type used by the service, such as TCP or UDP. The value ALL indicates that the rule applies to both protocols. The value must comply with the client configuration of the service.

External IP Address

Specify the host address used for accessing the external network. You can set it to the following:
Outbound Interface: You can select All WAN Ports or specify a WAN port. Enter or select an IP address: Select or enter the IP address of a WAN port.

125

Web-based Configuration Guide

Network-Wide Monitoring

Parameter

Description

External Port/Range

Specify the port number used for Internet access. You need to confirm the port number in the client software, such as the camera monitoring software. You can enter a port number or a port range, such as 1050-1060. If you enter a port range, the value of Internal Port/Range must also be a port range.

Internal IP Address

Specify the IP address of the internal server to be mapped to the WAN port, that is, the IP address of the LAN device that provides Internet access, such as the IP address of the network camera.

Internal Port/Range

Specify the service port number of the internal server to be mapped to the WAN port, that is, the port number of the application that provides Internet access, such as port 8080 of the Web service.
You can enter a port number or a port range, such as 1050-1060. If you enter a port range, the number of ports must be the same as that specified in External Port/Range.

3.14.4 Verification and Test
Check whether the external network device can access services on the destination host using the external IP address and external port number.
3.14.5 Solution to Test Failure
(1) Modify the value of External Port/Range and use the new external port number to perform the test again. The possible cause is that the port is blocked by the firewall.
(2) Enable the remote access permission on the server. The possible cause is that remote access is displayed on the server, resulting in normal internal access but abnormal access across network segments.
(3) Configure DMZ rules. For details, see Section 3.13.6 Configuration Steps (DMZ). The possible cause is that the specified ports are incorrect or incomplete.
3.14.6 Configuration Steps (DMZ)
Choose Local Device > Advanced > Port Mapping > NAT-DMZ. Click Add. Enter the rule name and internal server IP address, select the interface to which the rule applies, specify the rule status, and click OK. You can configure only one DMZ rule for an outbound interface.

3.20.3 Configuring Session Attack Prevention
1. Overview
Session Attack Prevention In a session attack, an attacker sends heavy traffic to the device. In this case, the device has to consume many resources when creating connections. To reduce the impact of the attack, you can limit the rate of creating sessions.
Flood Attack Prevention In a flood attack, an attacker sends tremendous abnormal packets to a device. As a result, the device uses a large amount of resources to handle the packets. This causes the device performance to deteriorate or the system to break down. If the value of TCP SYN and other TCP Flood parameters is too small, the authentication function and access to local web pages will be affected. If the value of UDP Flood parameter is too small, the DHCP address allocation, DNS domain name resolution, and VPN functionalities will be affected. You are advised to set the value to be greater than the load capacity of the local device.
Suspicious Packet Attack Prevention In a suspicious packet attack, an attacker sends tremendous error packets to the device. When the host or server handles the error packets, its system will crash.

3.21 Configuring TTL Rules
3.21.1 Overview
Time to live (TTL) aims to prevent unauthorized connections. It limits the number of devices that can transmit data packets in the network by limiting the existence time of the data packets in the computer network, so as to prevent infinite transmission of data packets in the network and the waste of resources. When TTL is set to 1 and is valid for LANs, packets are directly discarded when passing through the next router. If a user connects a router to Ruijie device without permission and connects a client to the router, packets cannot pass through the client, either.
