Vigor 300B Quad-WAN Load Balancer Overiew The Vigor 300B is a high-performance quad-WAN load balancer. The Vigor 300B provides high performance with Dray Tek's traditional ease of use & a comprehensive feature set with robust firewalling, flexible content filtering & multiple monitoring methods. Load Balancing & WAN Backup The four Gigabit WAN ports can provide load balancing or WAN failover. In failover mode, additional WAN connections are activated only when your primary or additional normal connectivity if interrupted. The failover/backup connections kick in automatically, keeping you online. In load balanced mode, up to four of the WAN fees are used all of the time, but your load (connections) is spread across all of the active connections, making the best use of your connectivity. Alternatively, the Vigor 300B can be set with load balance policies so that different traffic types use specific connections, for example reserving one connection for latency-sensitive or high priority data, or forcing low-priority data down your slowest connection. Extensive Qo S & VLAN facilities on the Vigor 300B help keep your network efficiency & online productivity at its best. The Vigor 300B can be rack-mounted (brackets provided) or used standalone.
