WAN Load Balancing

Up to 5 WAN links can be active simultaneously on Vigor3220 series, including 4 Gigabit Ethernet and 1 3G/4G cellular connection via a USB modem attached to the USB port. With default configuration, Vigor3220 automatically distribute the traffic among all active WANs and determines the load balancing weight based on the bandwidth utilization of each interface. Aggregated bandwidth can also be achieved by using "Session-Based" Load Balancing mode. Vigor3220 series also features Data Budget Tool to track the data usage on each WAN, which will be reset monthly (or on custom cycle), administrator can configured the router to shut down the interface immediately or send a notification when the data usage reaches a threshold.

A Robust VPN Server

Vigor3220 can be the VPN server allows up to 100 simultaneous connections, including LAN-to-LAN VPN with the branch offices, or the Host-to-LAN VPN for the teleworkers. All the industry standard tunneling protocols are supported, including PPTP, L2TP, IPsec, and GRE, and therefore are compatible with 3rd party VPN devices. SSL VPN is also included on Vigor3220, and DrayTek also offers free official client App for Windows, iOS, and Android. 

Vigor3220 also provides VPN redundancy to ensure the reliability of VPN connection. Two VPN tunnels to the same remote network but through different WAN interfaces can be configured into a VPN trunk. The two trunking tunnels can be set up in load balancing or failover mode.

VLAN and Multiple Subnet

Vigor3220 can provide high-speed Internet connectivity for up to 200 hosts, and the support of Virtual LAN Feature (VLAN) allows you to separate the whole LAN network into smaller logical domains, which will help to increase the local network security and improve network efficiency. Up to 8 IP subnet can be set up on Vigor3220 series, this enables each VLAN to use a different IP address range.
