Vigor 3910 Multi-WAN Ultra-High-Performance Router

The Vigor 3910 is specially designed to cope with the throughput demands of large networks and as a VPN concentrator, has suitable processing power to meet the demands of hundreds of active VPN tunnels.

Firewall and 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.

The Vigor 3910 features Multi-WAN connectivity with up to 8 WAN interfaces:

• 4 RJ-45 1GbE ports
• 2 RJ-45 2.5GBase-T (backwards compatible with 1GbE) ports
• 2 SFP+ module slots

The Ethernet and 2.5GBase-T ports can be connected to:

• Leased Lines
• DSL modems (e.g. Vigor 130) for ADSL, VDSL and G.Fast connectivity
• 4G and LTE through the Vigor 2620Ln in LTE bridge mode
• Cable modems
• Any other Ethernet-based Internet feed

The Vigor 3910 features 12 physical ports in total, with 8 ports that can be switched between LAN and WAN usage to fit your network requirements, with many combinations being possible: 

• 8 WAN interfaces with 4 LAN ports
• 4 WAN interfaces with 8 LAN ports
• 1 WAN interface with 11 LAN ports

These configurable LAN or WAN interfaces consist of:

The Vigor 3910 features a hugely flexible local network interface, with the router managing up to 100 separate Local Networks (or Subnets) through the use of 802.1Q VLAN Tags. Each network can be used in NAT or Routing modes, containing anywhere from 253 to 1022 devices each, with larger subnet support.

Each of the 100 VLAN subnets can be isolated from each other, for example to feed different companies or departments but keeping their local traffic completely separated. With Inter-LAN routing, specified networks can allowed to communicate with each other or share resources, with the router’s Firewall controlling access.

To take full advantage of VLAN tagging, the Vigor 3910 can be connected to any one of the switches from the DrayTek VigorSwitch range such as the VigorSwitch P2280x.

Security is always taken seriously with DrayTek routers. The firewall protects against attacks including DoS (Denial of Service) attacks, IP-based attacks and access by unauthorised remote systems.

The DrayTek object-based firewall allows even more setup flexibility than ever, enabling you to create combinations of Firewall rules and Content Filtering to suit a large office environment, applying Content Filtering to the whole network, only specified devices or just the network that guests can connect to.

The Vigor 3910 supports IPv6 - the successor to the current IPv4 addressing system that has been used since the Internet was first created. IPv6 can be provided directly by your ISP, but if your WAN interfaces do not (yet) support IPv6, the Vigor 3910 also supports IPv6 broker/tunnel services to provide IPv6 access using either TSPC or AICCU via 3rd party IPv6 providers over each of its interfaces. To learn more about IPv6, you read our detailed IPv6 guide here.

The advanced networking features of the Vigor 3910, such as the object-based Firewall, Quality of Service, Content Filtering and VLANs support both IPv4 and IPv6 networks.

The Vigor 3910 goes beyond 1 Gigabit throughput per port, with both 2.5GbE RJ-45 (copper) ports and 10GbE SFP+ ports.

The faster 10 Gigabit uplink capability allows you to make high bandwidth links to both WAN connections and LAN devices.

10GbE capable switches such as the VigorSwitch P2280x allow you to expand the router’s ports without the risk of creating a bottleneck. Connect other 10GbE capable devices such as Network Attached Storage and Servers to provide more throughput to your network.

The SFP+ ports provide compatibility with your choice of SFP / SFP+ modules (not included) and therefore the most appropriate medium for your application.

Connect a passive Direct Attach SFP+ cable such as the DrayTek DAC-CX10-01M to the SFP+ module port of 1Gbps/10Gbps capable Switches, Network Attached Storage and Servers, for a cost effective, up to 10Gbps network link.

The 2.5GbE ports can be connected to other devices that support the 2.5GbE standard over standard Cat5e copper cabling, or as they are backwards-compatible with 1GbE, they can be used simply to expand the number of available RJ-45 ports on the router.

The content control features of Vigor routers allow you to set restrictions on web site access, blocking download of certain file or data types, blocking specific web sites with whitelists or blacklists, blocking IM/P2P applications or other potentially harmful or wasteful content. Restrictions can be per user, per PC or universal and according to time schedules.

Content filtering can also block sites using HTTPS/SSL where URLs are encrypted (and normal routers cannot block).

Using the GlobalView service, you can block whole categories of web sites (e.g. gambling, adult sites etc.), subject to an annual subscription, which is continuously updated with new or changed site categorisations or sites which have become compromised (such as infected with Malware). A free 30-day trial is included with your new router.

The Vigor 3910 (along with most other DrayTek routers, Access points and switches) can be centrally managed by our VigorACS central management platform.

This scalable solution provides visibility, control and reporting of your entire DrayTek product estate, ideal for dealers/SIs managing customers' devices or any user who wants to know what's going on with their devices. VigorACS also provides features like automated/bulk firmware updates, VPN management and alarms for connectivity or other issues.

Prioritise latency-sensitive applications on your network with Quality of Service.

Use 4 separate queues to give priority to servers & PCs (IP address), services such as VoIP or DNS, or packet tagging used by IP phones with 802.1p and DSCP support

Auto Voice VLAN allows the router to automatically prioritise VoIP calls as they pass through the router without additional configuration.

Control throughput with Bandwidth Limit, by setting speed limits for all clients individually, groups of IPs, or a shared bandwidth limit for a whole subnet, such as a Guest network.

The Vigor 3910 can manage DrayTek VigorAP access points and VigorSwitch switches connected locally to the router. This enables you to centrally control, manage and administer multiple AP & Switch devices installed around your building/campus from just the one router.

Central AP Management

The DrayTek router operating as the wireless controller can provision up to 50 DrayTek VigorAP access points with Central AP Management profiles, with an option to Auto Provision - auto configuring newly installed VigorAP access points with the Auto Provisioning profile, upon initial connection to the DrayTek Vigor router's network.

Central Switch Management

DrayTek VigorSwitch switches can be provisioned and managed through the router with DrayTek’s Central Switch Management system, which allows you to:

• Easily provision VLAN configuration and other port settings directly from the router.
• Set bandwidth rate limits and schedules for individual ports.
• Log switch events for alert notifications if network problems occur
• At a glance see the devices connected on your network with a virtual topology.
