Key Features. Quad-Core processor Flexible WAN Architecture Switchable WAN and; LAN Ports. Powerful 10 Gb E-Capable Internet Gateway The Vigor 3910 is specially designed to cope with the throughput demands of large networks & as a VPN concentrator has suitable processing power to meet the demands of hundreds of active VPN tunnels. Firewall & NAT throughput of the router can exceed 9 Gigabits per second when connected via the 10 Gigabit SFP+ ports or spread over multiple Internet connections with Load Balancing. The Vigor 3910 accelerates LAN-to-LAN IPsec VPN throughput up to 3 Gigabits per second with up to 500 active VPN tunnels it can provide enough throughput to each tunnel without becoming a bottleneck to the user experience. The SSL VPN capabilities of the Vigor 3910 are also increased with over 1 Gigabit per second of total SSL VPN throughput suitable to cater to the bandwidth requirements of up to 200 active SSL VPN users. High-Performance VPN Concentrator A feature central to Dray Tek routers is its VPN (Virtual Private Networking) capabilities. A VPN enables you to link remote offices & branch offices back to HQ or home-based/mobile teleworkers back to your office. Once connected they have access to your office/remote resources through a secure encrypted tunnel allowing remote desktop file sharing & seamless access to other resources & devices. The Vigor 3910 means that you can have up to 500 simultaneous VPN tunnels to remote offices or teleworkers with over 3 Gbps of VPN throughput. It supports all common industry standard protocols encryption types & authentication methods (see
Specification tab for full support list). Teleworkers can authenticate directly with your LDAP server if preferred. The Vigor 3910 supports VPN trunking; this means that you can create tunnels down multiple WAN connections to a remote site in order to increase bandwidth. VPN trunking also provides failover (backup) of your VPN route down a secondary WAN connection. You can learn more about Dray Tek VPN here. Teleworkers can also use 2FA (Two factor authentication) such as MOTP. Load Balancing
- Ultimate Resiliency and; Reliability The SFP+ ports when fitted with an optional SFP+ or SFP module can be linked to 1 Gb E or 10 Gb E uplinks through Fibre or any other link type with a suitable transceiver. Fibre is of particular use for longer distance deliveries beyond the range of standard Ethernet or where copper connections cannot be used. These multiple WAN interfaces can be used either for WAN-Backup or Load Balancing with Policy-based Routing giving you full control of where & how traffic is routed. Load-balancing or failover supports IPv 4 only currently (not IPv 6). 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 are restored to your primary Internet line all traffic is switched back to that. Flexible WAN and; LAN Ports The Vigor 3910 features 12 physical ports in total with 8 ports that can be switched between LAN & WAN usage to fit your network requirements with many combinations being possible High Availability For even greater resilience the Vigor 3910 provides High Availability (HA) with both a primary & secondary router able to provide connectivity to your network & subnets. In the event of the primary unit failing the secondary unit will take its place on the network automatically switching over to resume Internet routing & VPN connectivity with no intervention required. This can remove the possibility of a single point of failure within your routers. With Config Sync the two routers are managed as a single unit so that any changes made to the primary router will automatically propagate to the secondary router ensuring it’s ready
