DrayTek VIGOR300B Quad-WAN Load Balancing High-Performance Router

WAN Load Balancing

Vigor300B offers WAN throughput up to 1 Gbps, there are 4 Gigabit Ethernet WAN port for either load balance or failover applications, up to 2 3G/4G USB modems can be attached to the USB ports to add additional cellular connectivity. Up to 6 physical WAN connections can be active simultaneously to provide a high-performance as well as high-availability network, these make Vigor300B a perfect gateway for a network with web servers or data center.

Inbound Load Balancing

While acting as an authoritative DNS server, VIgor300B can also perform inbound load balancing to distribute the incoming connection requests across multiple WAN links to the server behind Vigor300B, thus to provide load balancing as well as failover for the inbound connections.

Local Network Management

The 2 Gigabit Ethernet LAN ports of Vigor300B provides high-speed connectivity for the servers and PCs on the local network, and the support of Virtual LAN (VLAN) allows you to separate the local network into different logical domains thus to increase the security and network efficiency, and each VLAN can use a unique IP subnet. As for IP assignment for the LAN clients, except for the commonly-used DHCP, Vigor300B also supports being a PPPoE server to provide  independent connections between the LAN hosts and Vigor300B over a multiple-access network.

Bandwidth management feature can help you to make the most of out of the available bandwidth. You may set up Bandwidth Limit or Session Limit to restrict the maximum bandwidth or session number that a host can use, thus to prevent the bandwidth and the router's resources being occupied by a single host. Quality of Service (QoS) allows you to reserve a certain amount of bandwidth for the critical clients or time-sensitive applications, and ensure their connection quality when traffic is heavy.
