Dual WAN Configuration on RV320 and RV325 VPN Router Series
WAN is a network that consists of multiple LANs. The RV32x VPN Router Series supports a dual WAN feature that allows both WAN ports to be used simultaneously. The WAN connections can also be configured as a failover setup to ensure continuous Internet connectivity. To further optimize dual WAN use, the RV32x VPN Router Series uses protocol binding. Protocol binding allows for specific traffic to be sent through a specific WAN port.
This article explains how to configure dual WAN on the RV32x VPN Router Series.
• RV320 Dual WAN VPN Router • RV325 Gigabit Dual WAN VPN Router
Step 1. Log in to the Web Configuration Utility and choose System Management > Dual WAN. The Dual WAN page opens:
Step 1. Click the radio button that corresponds to the desired dual WAN mode.
• Smart Link Backup — This option ensures continuous WAN connectivity on the router. If the primary WAN loses connection, the backup WAN takes over. Choose the WAN that is designated as the primary WAN from the drop-down list.
• Load Balance — Use both WAN connections simultaneously. This increases the available bandwidth for the router.
Step 2. Click Save. The dual WAN mode is configured.
Edit Wan Interface
Step 1. Log in to the Router Configuration Utility and choose System Management > Dual WAN. The Dual WAN page opens:
Step 2. Click the radio button of the interface you want to edit.
Step 3. Click Edit.
Refer to the following subsections for information about the blank window.
• WAN Bandwidth — How to configure bandwidth for a specified WAN interface.
• Manage Protocol Binding — How to configure a protocol binding for a specified WAN interface. Protocol bindings determine which WAN interface is used for certain traffic.
Step 1. Enter the maximum upload bandwidth in kilobits per second provided by your ISP in the Upstream field.
Step 2. Enter the maximum download bandwidth in kilobits per second provided by your ISP in the Downstream field.
Step 3. Click Save. The bandwidth settings are configured.
Network Service Detection
Step 1. Check EnableNetwork Service Detection to allow the router to detect connectivity. This is performed through a ping test which is performed on a configured IP address.
Step 2. Enter the number of times the router tries to ping the configured IP address in the Retry Count field.
Step 3. Enter how many seconds the router waits between pings in the Retry Timeout field.
Step 4. From the When Fail drop-down list, choose an action to take place when a ping test fails.
• Keep System Log and Remove the Connection — A failover occurs and the backup WAN interface takes control. The primary WAN resumes control when the connection to the primary WAN is restored.
• Generate the Error Condition in the System Log — A failure is recorded in the system log and no failover takes place.
Step 5. Check the check box of the location that is to be pinged for the ping test.
• Default Gateway — The RV320 pings the configured default gateway.
• ISP Host — Enter the IP of the ISP host for the router to ping.
• Remote Host — Enter an IP of a remote host for the router to ping.
• DNS Lookup Host — Enter a host name or domain name for the router to ping.
Step 6. Click Save. The network service detection settings are configured.
Manage Protocol Binding
Add Protocol Binding
Protocol Binding is a feature that is used to send specific traffic through a specific WAN interface. Any traffic that matches the type of traffic and is sent from the configured source IP addresses to the configured destination addresses is sent through the configured WAN interface of the protocol binding rule. Protocol Binding is only available if the dual WAN mode is configured as load balance.
Step 1. Click Add in the Protocol Binding Table to add a new protocol binding to the specified WAN interface.
Step 2. From the Service drop-down list choose the type of traffic that will apply to the protocol binding.
Step 3. Enter the source IP addresses that will apply to the protocol binding in the Source IP field.
Step 4. Enter the destination IP address that will apply to the protocol binding in the Destination IP field.
Step 5. From the Interface drop-down list choose the interface that the traffic will go through.
Step 6. Check the check box in the Status field to enable the protocol binding.
Note: Click Service Management to add a service. Click here to go to the Service Management section.
Step 7. Click Save. The protocol binding settings are configured.
Edit Protocol Binding
Step 1. Check the check box of the protocol binding you want to edit.
Step 2. Click Edit in the Protocol Binding Table.
Step 3. From the Service drop-down list choose the service that will apply to the protocol binding.
Step 4. Edit the source IP addresses that will apply to the protocol binding in the Source IP field.
Step 5. Edit the destination IP address that will apply to the protocol binding in the Destination IP field.
Step 6. From the Interface drop-down list choose the interface that the traffic will go through.
Step 7. Check the check box in the Status field to enable the protocol binding.
Step 8. Click Save. The protocol binding configuration is updated.
Delete Protocol Binding
Step 1. Check the check box of the protocol binding you want to delete.
Step 2. Click Delete in the Protocol Binding Table.
Step 3. Click Save. The protocol binding configuration is deleted.
Step 1. Click Service Management. The Service Management window appears.
Step 2. Click Add to add a new service.
Step 3. Enter a name for the service in the Service Name field.
Step 4. From the protocol drop-down list choose the protocol that the service uses.
• TCP — The service forwards Transmission Control Protocol (TCP) packets.
• UDP — The service forwards User Datagram Protocol (UDP) packets.
• IPv6 — The service forwards all IPv6 traffic.
Step 5. If the protocol is either TCP or UDP, enter the range of ports that is reserved for the service in the Port Range field.
Step 6. Click Save. The service is saved to the Service Management Table.
Step 7. (Optional) Check the check box of the service you want to edit, click Edit, edit the desired fields and click Save. A warning window appears. Click Yes. The service configuration is updated.
Note: Any configuration that is associated with the edited service will be automatically updated.
Step 8. (Optional) Check the check box of the service you want to delete, click Delete and click Save. A warning window appears. Click Yes. The service configuration is deleted.
Note: Any configuration that is associated with the deleted service will be automatically deleted.
