Multi-WAN routers distribute network traffic across multiple internet connections through load balancing, helping a site make better use of available bandwidth. They can also direct specific traffic through a selected WAN connection based on configured network policies, service needs, or connection status.

Plan for an Ethernet connection from each internet service, a LAN connection to the internal network, and enough switch or patch-panel capacity for the router’s available ports. For multi-WAN failover or load balancing, reserve a dedicated WAN port and, when provided, a configurable WAN/LAN port, match connected equipment and cabling to the port speed, and provide a Cloud Key, hosted controller, or UniFi Network server when the gateway requires external management.

Multi-WAN routers can connect with existing network management through a UniFi Network controller, Cloud Key, hosted service, or network server, depending on the gateway configuration. They also add routing and security functions such as load balancing, intrusion detection and prevention, stateful firewall controls, and VPN support to help manage traffic and protect connected devices.

When comparing multi-WAN routers, review multi-WAN load balancing, configurable WAN and LAN ports, routing throughput with intrusion detection and prevention enabled, and whether the firewall provides stateful traffic inspection. For virtual private network (VPN) use, check the router’s supported VPN capabilities, expected performance under secure connections, and management method, such as integrated network management or a separate controller.
