Fig. 6-1-4 Uplink Settings Interface

Link Detection Switch: The device has link detection functionality enabled by default. However, in certain specialized network environments where external communication is not possible, users may need to manually disable link detection. When link detection is turned off, users won't be able to view latency, jitter, packet loss, signal strength, and other information for upstream interfaces in the [ Status ] menu.

Notes:

  1. Modifying settings in the Internet menu can potentially lead to a disruption in device connectivity. Exercise caution when making changes.
  2. When the link detection address is left empty, the default behavior is to detect the DNS address via the upstream interface. If you specify a detection address, all upstream interfaces will only detect the address you provided.
  3. In the router's link backup mode, users can customize detection parameters, and the device will switch links based on the enabled detection items. When detection items are not enabled, upstream link switching will only occur based on priority and link connectivity.
  4. In the device's load balancing mode, all operational upstream links will forward business traffic, provided they are functioning correctly.

6.2  Local Network

In the [ Local Network ] feature, users have the flexibility to define their local subnets. This includes configuring the address range, VLAN ID, DHCP services, and other related parameters for the local LAN. Once the configuration is complete, users need to further apply these settings to the device's LAN port through [ Interface Management ] or apply them to the desired SSID in the Wi-Fi settings. This series of operations is intended to ensure that client devices can smoothly connect to the local network according to the planned network addresses.

  6. Username/Password: Usernames and passwords that need to be the same on both ends for L2TP negotiation.
  7. Authentication Mode: Setting the L2TP authentication mode.
  8. Enable Tunnel Verification Function: When enabled, the usernames/passwords for tunnel verification on both ends need to be the same.

6.4.3   VXLAN VPN

VXLAN（Virtual Extensible LAN）is essentially a tunnelling technology that establishes a logical tunnel over an IP network between the source and destination network devices. It achieves data transmission and forwarding by encapsulating user-side packets in a specific manner.
Click the "Add" button under "VPN > VXLAN VPN" to create a new VXLAN VPN.

Fig. 6-4-3 Add a VXLAN VPN

  1. Name: Set the name for this VXLAN VPN network.
  2. Upstream Interface: The outbound interface used to establish a VXLAN tunnel with other devices.
  3. Peer Address: Configure the IP address of the peer device with which this device needs to establish a VXLAN VPN network.
  4. VNI: The VXLAN Network Identifier, where each VNI represents a different tenant or network segment.
  5. Local Subnet: Specify the address range assigned to local client devices when they connect.
Note:
  1. VXLAN cannot be used with other VPN functions and IP Passthrough functions at the same time.

6.5  Security

In the [ Security ] menu, users can configure advanced features related to firewalls, policy routing, and traffic shaping.

6.5.1   Firewall

The firewall currently includes functions such as inbound rules, outbound rules, port forwarding, MAC address filtering, and more.

6.5.1.1 Inbound Rules/Outbound Rules

You can implement traffic in/out control based on interfaces through the "Security > Firewall > Outbound Rules/Inbound Rules" feature. For example, if a user is subjected to a significant amount of attacks from a specific source IP address, they can use inbound firewall rules to restrict traffic from that IP address.

Fig. 6-5-1-1-a Firewall Function Entry

Furthermore, IT personnel can utilize outbound firewall rules to restrict certain users' access to external networks. Inbound and outbound rules share the same configurable content, with the only distinction being the default rules.

Fig. 6-5-1-1-b Add inbound/outbound rule

  1. Name: Set the name of the inbound/outbound rule for local identification.
  2. Status: Rule function switch.
  3. Interface: For outbound rules, it specifies the upstream interface where traffic leaves the router. For inbound rules, it specifies the upstream interface where traffic enters the router
  4. Protocol: Match traffic based on the protocol type, with options like Any, TCP, UDP, ICMP, or custom.
  5. Source: Match the source address for traffic, supporting custom, with the default as Any.
  6. Destination: Match the destination address for traffic, supporting custom, with the default as Any.
  7. Action: Action taken for matching traffic in inbound/outbound rules, supporting allow and deny.
  8. Inbound Rules: Traffic management rules for external network accessing the router, with the default as deny all.
  9. Outbound Rules: Traffic management rules for traffic going out through the router, with the default allowing all.
  10. Support for adjusting the priority of inbound and outbound rules.

6.5.1.2 Port Forwarding

Port forwarding, also known as port mapping or port redirection, is used to redirect network packets from one network port (or address) to another network port or address. Users can configure port forwarding rules under "Security > Firewall > Port Forwarding." When external traffic accesses a specific port on the router, the device forwards the data to the corresponding port of an internal client, enabling external access to services inside the router.
For example, when a user needs to access the service on port 1024 of the internal client at 192.168.2.10 from the external network, they can map this client's port to port 1024 under the WAN1 interface. External users only need to enter "https://WAN1 address:1024" in their browser to access the target device's data, where the WAN1 address is the IP address of the WAN1 interface.

Fig. 6-5-1-2 Add a Port Forwarding Rule

  1. Name: The name of the port forwarding rule, used for local identification.
  2. Status: The on/off switch for the port forwarding rule.
  3. Interface: The upstream interface that provides mapping functionality for internal clients. The upstream interface needs public IP address support.
  4. Protocol: The protocol type of the traffic for port mapping, supports TCP, UDP, and TCP & UDP.
  5. Public Port: The port number on the upstream interface that provides mapping
  6. Local Address: The address of the target device located under the router that the external network needs to access.
  7. Local Port: The port of the target device that the external network needs to access. It needs to be consistent with the public port input range.

6.5.1.3 MAC Address Filter

MAC address filtering involves allowing or disallowing devices in a MAC address list to access the internet, which means controlling LAN devices' internet access requests through MAC address filtering on the router. Users can configure MAC address filtering rules in "Security > Firewall > MAC Address Filtering."
 You can create multiple MAC addresses in the list, add address descriptions, and set it to allow only the MAC addresses to access the network (whitelist), or you can block MAC addresses in the list from accessing the network (blacklist).

Fig. 6-5-1-3 Add a MAC address filter rule

6.5.2   Policy-Based Routing

Policy routing is a feature that allows users to create policies based on their specific needs, enabling them to route different data flows through different links. This improves the flexibility and control of routing decisions, enhances link utilization efficiency, and reduces enterprise costs. Click the "Add" button under "Security > Policy Routing" to create a new policy routing rule.

Fig. 6-5-2  Add a router policy

Cations:

  1. The source address and destination address in a policy routing rule cannot both be set as "Any."

6.5.3  Traffic Shaping

Create a traffic shaping policy to optimize your network based on each protocol, giving users control and prioritizing critical business traffic. This feature can also reduce the bandwidth allocated to entertainment traffic.You can configure traffic shaping rules in "Security > Traffic Shaping > Add/Edit."

Fig. 6-5-3-a Traffic Shaping interface


Fig. 6-5-3-b Add a traffic-shaping rule

Traffic shaping policies consist of a series of rules executed sequentially, similar to custom firewall rules. Each rule comprises two main components: the type of traffic to restrict or adjust and how to limit or adjust that traffic.

Notes:

  1. Traffic forwarding priority for unmatched rules is medium.
  2. When Limit Bandwidth is set to 0, the system will not limit the bandwidth.
  3. The value of Reserved Bandwidth should not be greater than the Limit Bandwidth.

6.6  Services

6.6.1  Interface Management

You can configure local networks allowed through a specific interface and set the interface's speed in the "Services > Interface Management" function.

Fig. 6-6-1-a Interface Management


Fig. 6-6-1-b Edit the interface

6.6.2   DHCP Server

The DHCP (Dynamic Host Configuration Protocol) service operates in a client/server communication mode, where clients request IP addresses from servers, and servers respond to these requests by assigning IP addresses dynamically to clients.You can configure the DHCP server’s IP address pool using the "Services > DHCP Server" feature.
Fig. 6-6-2 DHCP Server

Notes:

  1. The device's DHCP service is generated based on the network information in the local network. If you remove a local subnet from the "Local Network List," the DHCP Server for that local subnet will also be deleted.
  2. Local network entries need to be set in “IP” mode for the DHCP server function to take effect. Networks in “VLAN Only” mode are not within the selectable range.

6.6.3   DNS Server

DNS (Domain Name System) servers are a crucial network component responsible for translating human-readable domain names (e.g., www.example.com) into computer-understandable IP addresses (e.g., 192.168.1.1). DNS servers act as the address book of the internet, helping computers and devices find the locations of other devices and ensuring that information can be correctly delivered across the network.
When users don't set DNS server addresses in "Services > DNS Server," the DNS addresses obtained from the device's upstream interface will be used for domain name resolution. When users configure DNS server addresses, the configured DNS addresses will be used for domain name resolution.
Fig. 6-6-3 Add a DNS server

6.6.4   Fixed Address List

You can use the "Services > Fixed Address List" function to allocate a fixed IP address to a device based on its MAC address. This means that the device will consistently receive the same IP address every time it connects to the ER805.
Fig. 6-6-4 Add a fixed IP address

Cautions:

  1. The available addresses for allocation must fall within the address range of the local network in IP mode, or else the configuration will not take effect
  2. When the local network is deleted, all fixed address allocation rules within the local network's address range will be removed.

6.6.5   Static Routes

You can configure static routing entries using the "Services > Static Routing" feature to enable data to be forwarded through specified paths and interfaces. The contents of the static routing table are manually created by users, and routing entries generated by other services, such as VPN functionality, will not be displayed in this table.
Fig. 6-6-5 Add a static route

Cautions:

  1. For static routes with the same destination address/network, the next-hop address, interface, or priority cannot be the same; otherwise, it will result in a non-functional route.
  2. When WAN2, Wi-Fi (STA), or L2TP Client VPN is deleted, the corresponding static routes using those interfaces will also be removed.

6.6.6   Dynamic DNS

Dynamic DNS (Dynamic Domain Name System) is used to automatically update the name server content in the domain system. According to internet domain rules, domain names are typically associated with fixed IP addresses. Dynamic DNS technology allows users with dynamic IP addresses to have a fixed name server. This enables external users to connect to the URL of users with dynamic IP addresses through regular updates.
You can manually configure the Dynamic DNS server address under the "Services > Dynamic DNS" feature.
Fig. 6-6-6 Add a Dynamic DNS service
  1. Service Provider: Provided by the Dynamic DNS service operator, you can choose from dyndns, 3322, oray, no-ip, or use a custom option (requires a URL).
  2. Hostname: Register for a hostname by clicking on the URL below the service provider.
  3. Username: Register for a username by clicking on the URL below the service provider.
  4. Password: The password set by the user during registration.

6.6.7   Passthrough Settings

You can enable the IP Passthrough feature through "Service > Passthrough Settings." Once enabled, client devices can obtain the upstream interface address of the ER805.
Fig. 6-6-7 Enable the IP Passthrough
  1. Passthrough MAC: Only clients bound to this MAC can obtain the upstream interface address of the device.

Cautions:

  1. When the IP Passthrough mode is enabled, only one client can access the public network. : static routing, VPN,  policy-based routing, SD-WAN Overlay, and cloud connectivity.
  2. When accessing client devices, you need to release inbound rules.
  3. You can still access the router via the default subnet's IP address.

6.7  System

In the "System" menu, users can configure settings related to cloud management, remote access control, clock settings, device options, configuration management, device alerts, tools, and log servers, among other functions.

6.7.1   adm Management

The initial username and password for the device are "adm" and "123456." To ensure the security of your device, it's recommended that you change the password. You can do this by clicking on "adm" in the top navigation bar and selecting "Change Password" from the dropdown menu.

Fig. 6-7-1 Modify the Password

6.7.2   Cloud Management

ER805 automatically connects to the InCloud Service after establishing an internet connection by default. If you do not wish to use the cloud management function, you can disable it manually in the "System > Cloud Management" function.

Fig. 6-7-2 Enable the InCloud Service

6.7.3   Remote Access Control


Fig. 6-7-3 Set the parameters of remote access

  1. HTTPS: When enabled, users can access the router's web interface remotely by entering the public IP address and port number of the upstream interface in a web browser.
  2. SSH: When enabled, users can remotely log in to the router's backend using remote tools (such as CRT) by providing the public IP address, port number, username, and password.
  3. Ping: When enabled, the upstream interface allows external networks to initiate Ping requests.

6.7.4   System Clock

You can use the "System > Clock" function to select their current time zone and configure NTP (Network Time Protocol) server addresses to synchronize the device's system time with an NTP server.

Fig. 6-7-4 Set the time zone and NTP server

6.7.5   Device Options


Fig. 6-7-5 Device Options

Cautions:

  1. When performing a local firmware upgrade, it is essential to ensure that the firmware is obtained from a legitimate source to avoid rendering the device inoperable due to incorrect firmware imports.
  2. When a device is connected to the cloud platform, the platform will synchronize the previous configuration to the device again due to cloud-based configuration synchronization. The device will only clear historical data during the factory reset.

6.7.6   Configuration Management

Configuring backups and backup recovery are critical tasks in network management and maintenance. They involve saving the configuration information of network devices so that it can be quickly restored or transferred when needed.
Users can export device configurations to local storage in the "System > Configuration Management" menu. This backup can be imported into the device in case of configuration loss or when you need to overwrite the existing configuration.

Fig. 6-7-6 Configuration Management interface

6.7.7   Device Alarms

You can choose to focus on specific events that may occur on the device by selecting the corresponding alarm events and configuring the email address for receiving alerts. When an alarm event occurs, the device will automatically send an email notification. It's important to note that even if a user doesn't select certain alarm options, related alarm events will still be recorded in the device's local logs.
You can configure alarm event types and email addresses for alarm notifications in the "System > Device Alarms" menu.

Fig. 6-7-7-a Alarm event types

After configuring the outgoing email server address, port, username, and password, the device will use this email account to send alarm notifications. You can use the "Send Test Email" option to verify whether the outgoing email configuration is correct. This test email will help you ensure that the device can successfully send alarm notifications to the specified email address.


Fig. 6-7-7-b Mail receiving settings

6.7.8   Tools

6.7.8.1 Ping

You can use ICMP (Internet Control Message Protocol) to check the device's external network connectivity. In the "Target" field, enter any domain name or IP address you want to test the device's connectivity to, and then click "Start" to check the connectivity status between the device and the specified target. This can help you determine whether the device can reach the target over the internet.
You can perform a network ping test on a target by going to "System > Tools > Ping." This allows to send ICMP echo requests to the specified target IP address or domain name and receive ICMP echo replies to check network connectivity and latency to that target.

Fig. 6-7-8-1 Ping

6.7.8.2 Traceroute

Traceroute is a network diagnostic tool used to determine the network path that data packets take from the source to the destination, as well as the intermediate routers or hops along that path.You can enter the target host's IP address in "System > Tools > Traceroute," choose the outgoing interface for the traffic, click "Start," and check the device's connectivity to the target IP by tracing the route.

Fig. 6-7-8-2 Traceroute 

6.7.8.3 Capture

Packet capturing is a network monitoring and analysis technique used to capture and record data packets transmitted over a computer network. Packet capture tools are typically used for network troubleshooting, network performance analysis, security auditing, and protocol analysis, among other purposes.
Users can capture packets passing through a specific interface in "System > Tools > Packet Capture." By selecting the "Output" option, users can choose to display the captured data within the interface or export it locally for further analysis.

Fig. 6-7-8-3 Capture

6.7.9   Scheduled Reboot

Scheduled reboot is a network device management strategy that allows administrators to automatically restart a device at a specific time or under certain conditions to ensure the device's normal operation and performance.
In practice, users can set up scheduled reboots in the "System > Scheduled Reboot" function based on their business requirements. The device supports scheduled reboots at fixed times daily, weekly, or monthly.
In the case of monthly reboots, if the selected reboot day exceeds the actual number of days in the month, the device will reboot on the last day of the month. For example, if you choose to reboot on the 31st of every month, it will reboot on the 30th in a month with only 30 days.

Fig. 6-7-9 Set the scheduled reboot time

6.7.10 Log Server

A log server is a dedicated server or software application used to collect, store, and manage log information generated by network devices, applications, and operating systems. These log records include events, warnings, errors, activities, and other relevant information and are crucial for monitoring, troubleshooting, and performance optimization.
When users enable the log file server function in the "System > Log Server" feature, the device will periodically upload log files to the specified log server.

Fig. 6-7-10 Set the log server address

6.7.11 Other Settings

6.7.11.1   Web Login Management

When a user logs in to the local interface of the device through the web and the session remains active for a certain period, it will automatically log out or disconnect to protect the user's privacy and security.
You can configure the logout time in "System > Other Settings > Web Login Management." If the online time during a single login session on the device's web page exceeds the configured time, the system will automatically log the user out, and they will need to log in again to continue their operations.

Fig. 6-7-11-1 Set the web page logout time

6.7.11.2  Accelerated Forwarding

This feature can be used to accelerate packet forwarding and enhance network performance. It is turned off by default.After enabling this feature in "System > Other Settings > Accelerated Forwarding," the device's cellular speed will significantly improve.

Fig. 6-7-11-2 Enable the accelerated forwarding

Cautions:

  1. Enabling this feature will disable the normal functioning of IPSec VPN, traffic shaping, and other related features.

6.7.11.3  Automatically Restarts

This feature can be used to quickly forward packets, improving network performance. By default, it is turned off. When users enable this feature in "System > Other Settings > Fast Forward," the device's data forwarding rate will significantly increase.

Fig. 6-7-11-3 Enable the Automatically

6.7.11.4   SIP ALG

SIP ALG consists of two technologies: Session Initiation Protocol (SIP) and Application Layer Gateway (ALG). This protocol is typically used to assist in managing and handling SIP communications (Session Initiation Protocol for establishing and managing real-time communication sessions, such as voice and video calls).
Users can enable this feature in "System > Other Settings > SIP ALG."

Fig. 6-7-11-4 Enable the SIP ALG

Note：

  1. If the connected device needs to engage in VoIP (Voice over Internet Protocol) phone communication, it is recommended to disable this function.

6.7.12 SD-WAN

Backgroud:
Between enterprise branches, there is often a need for mutual access to facilitate business data transfer, video conferencing, and other requirements. Traditional VPN configurations can be complex and troubleshooting can be challenging. InHand Networks introduces SD-WAN network functionality, which, through a user-friendly interface, assists users in rapidly establishing connections between branches. This not only enhances link flexibility but also significantly reduces operational and management complexity, ultimately providing enterprise users with a better network experience.

Fig. 6-7-12-a Application Scenarios
Process：

Fig. 6-7-12-b Application Scenarios


6.7.12.1  Create Network

In the platform's "Network" function, select "SD-WAN," click on "Add," and you will be redirected to the SD-WAN network addition page.

Fig. 6-7-12-1-a SD-WAN Entry

Fig. 6-7-12-1-b Create SD-WAN Network

The current SD-WAN network supports the Hub & Spoke topology, with device roles divided into central and branch devices. All branch devices establish tunnels through the central device, and traffic between branch devices passes through the central device.
Hub:
  1. Central devices require a public IP address to ensure the operation of the SD-WAN network. Users can also address the issue of insufficient public IPs through IP mapping.
  2. Tunnels are established between the central device's upstream interface with public IP addresses and all upstream interfaces of the branch devices.
  3. In the firewall rules, the central device's upstream device needs to allow two port numbers and map them to the upstream interface of the ER series router. The port range is 1-65535.
  4. Supported device models: ER805, ER605, ER2000
  5. A maximum of 5 devices can be added.
Spoke:
  1. Branch devices have no specific requirements for public IP addresses.
  2. Multiple branch devices can be added, with the final number determined by the performance of the central device.
  3. Supported device models: ER805, ER605.

6.7.12.2  Add device

On the "Add Network" page, click the "Add" button for either the central device or branch device, depending on the type of device you want to add to the network.After selecting the device, provide the public IP mapping information for the device.
