Multiple WAN Policy

The Multi-WAN function allows the router to connect to multiple WAN landlines to pile up and increase the total bandwidth and speed. It has 4 routing modes available, default is Intelligent line selection mode. You can choose the other modes according to the different applications.

If you have only one internet landline, you do not need to set up this section just except for the line detection function.

The priority queue is:
Policy Routing > Application Diversion > Multi-WAN Mode Settings

Multi-WAN Routing Mode

1) Intelligent line selection
Choose the routing according to landline operators, use in the conditions of using multiple landlines from multiple operators. This routing mode realizes the corresponding games and applications telecommunications to solve the network delay problem between landline providers.

2) Main/auxiliary mode
It is recommended to use one fiber with multiple ADSL lines. Need to enable the application scheduler at the same time. Without [Application scheduler], all traffic will only go to the main line, the auxiliary line will not have any traffic by default. When the fiber optic line has a tight bandwidth, you should choose an ADSL or dial-up line as the main line, and set up the specific application, such as gaming applications, go through fiber optic line configured by the [Application scheduler] rules.

3) Load balancing mode
When using the same type of landlines from the same carrier, load the landlines balanced according to the proportion of bandwidth and stacking the total bandwidth. The distribution of each landline traffic depends on the weight of the interface priority. You can configure the interface priority in advanced interface settings.

4) Active/standby mode
Connect the other lines when the main line is offline.

Note:
After selected the multi-WAN mode, but does not configure the [Application scheduler], all traffic will be allocated to each line in the manner defined by the routing mode. After modified the multi-WAN mode and has not rebooted the router, it does not affect the line selection mode of the old connection. Only the new connection will distribute traffic to each line according to the new configuration.

Add New Application Scheduler

Grpups of IP, Time and Port
Use the existing groups or create new groups of source IP, destination IP, time IP, and port.

High flow application
Enable mass data flow applications including P2P, video streaming, web music, fake IE, download and so on.

Application Protocol
Click to add the protocols.

WAN Interface
Define the WAN port for the selected protocols.

Cautions:

1. Small traffic protocols and applications are not recommended to participate in traffic distribution, such as DNS, ICMP, etc.

2. Massive traffic protocols and applications such as P2P downloads, network video, network TV, fake IE (common applications), software updates, and file transfers. You can divide the data flow according to the network bandwidth. The traffic distribution of each outbound interface depends on the interface weight. You can change the interface priority weight in [Advanced Settings] – [Interface Advanced Settings].

3. In the intelligent line selection and the main and auxiliary modes, if the primary WAN interface has sufficient bandwidth, you need not configure a specific rule for the gaming applications. You can select only one WAN interface when configuring for the network gaming application.

4. After modifying the configuration of application traffic distribution but has not rebooted the router, it does not affect the line selection mode of the old connection. Only the new connection will be offloaded to the designated line according to the new configuration.

PBR Rules

Policy-based routing (PBR) is a technique that forwards and routes data packets based on policies or filters. Network administrators can selectively apply policies based on specific parameters such as source and destination IP address, source or destination port, traffic type, protocols, access list, packet size, or other criteria and then route the packets on user-defined routes.

The goal of PBR is to make the network as agile as possible. By defining routing behavior based on application attributes, PBR provides flexible, granular traffic-handling capabilities for forwarding packets. In this way, PBR enables network administrators to achieve optimal bandwidth utilization for business-critical applications.

Cautions
After modified the policy routing configuration but has not rebooted the router, it does not affect the line selection mode of the old connections. Only the new connections will allocate traffic to the specified line according to the new configuration.

Line Detection

Prevent non-working connections, stabilize the WAN connections, and automatically switch to other available WAN interfaces.
Line detection method:
Ping gateway or ping DNS can detect the WAN interface connection. When WAN interface disabled ping connection, use DNS or ARP detections.

Cautions:

1. Only static IP or dynamic IP connections need the line detection function. PPPoE ADSL connection does not fit to the line detection function.
2. Suggest disables line detection when having only one WAN or 4G connection.

3. When having multiple WAN connections, if detected disconnected line, it will automatically switch the traffic to other lines.

4. The default is ARP detection. It is recommended to use any of the Ping detection methods when Ping is allowed on the external WAN network.
