Vigor 3220 Quad-WAN Router Firewall & Load Balancer
The Vigor 3220 is a router/firewall with four Gigabit Ethernet WAN ports, providing load balancing or failover for up to four WAN connections of any type.
The Vigor 3220 is based on DrayTek's own DrayOS operating system, providing familiarity for users of other existing DrayTek products.
The Vigor 3220 supports many professional features such as VLAN tagging, QoS (Quality of Service Assurance), High Availability, DNS Filter, Policy Based Routing, and User Access Control. Wired and Wireless models also include our new Hotspot features. If you deploy DrayTek Wireless Access Points, the Vigor 3220 can act as the Central Management Controller (click on any of those links for an explanation of each feature).
For mission critical applications, a pair of Vigor 3220's can be set up in high-availability mode - also known as 'hardware failover'.
This removes the Vigor 3220 as a single point of failure if it ceases operation or is damaged - the standby router takes over operations.
WAN Load Balancing & Backup
The Vigor 3220's multiple WAN interfaces can be used either for WAN-Backup or load balancing. Each of the 4-WAN Ethernet ports can be connected to any Ethernet-based Internet connection, such as a DSL modem, cable modem, leased line etc.
The USB port provides Internet connectivity (main, backup or load balanced) by connecting to a compatible USB modem (or cellphone) for access to the high speed 3G/4G/LTE cellular networks from UK providers such as Vodafone, O2, 3 and EE. If you don't have a wired Internet connection at all, the USB/3G/4G access method can be used as your primary/only Internet connection, ideal for temporary locations, mobile applications or where broadband access is not available.
The ethernet ports can connect to DSL modems (e.g. Vigor 130), a cable modem or any other Ethernet-based Internet feed. The multiple WAN interfaces can be used either for WAN-Backup or Load Balancing. Load-balancing or failover supports IPv4 only currently (not IPv6).
WAN-Backup provides contingency (redundancy) in case of your primary Internet connection or ISP suffering temporary outage). Internet Traffic will be temporarily routed via the secondary Internet access. When normal services is restored to your primary Internet line, all traffic is switched back to that.
