WAN Load Balancing

Vigor3900 offers WAN throughput up to 1 Gbps, there are 4 Gigabit Ethernet WAN ports and 1 SFP slot 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 7 physical WAN connections can be active simultaneously to provide a high-performance as well as high-availability network.

While acting as an authoritative DNS server, VIgor3900 can also perform inbound load balancing to distribute the incoming connection requests across multiple WAN links to the server behind Vigor3900.

High Capacity VPN

As a VPN concentrator, Vigor3900 allows up to 500 concurrent VPN connection, including LAN-to-LAN and Teleworker-to-LAN VPN. All the industry standard tunneling protocols are supported, including PPTP, L2TP, IPsec, IKEv2, and GRE. DrayTek SSL VPN is also provided. Vigor3900 also features VPN trunking, which allows you to establish multiple VPN tunnels to one remote network but through different WAN links. The two trunking tunnels can be used for load balancing application to increase the VPN throughput, or to be used in failover mode to provide a backup access.

User Management

Vigor3900 provides an integrated solution for local user management. Besides being a VPN gateway for remote dial-in users, it can also be a PPPoE server to authenticate LAN clients and track data usage of each client; and also a web portal server for authenticating guests and displaying information. Vigor3900 supports user authentication based on local user profiles or external authentication servers, including RADIUS and LDAP/Active Directory. Furthermore, Vigor3900 allows user-based management rules, content filtering policies and bandwidth management policies can all be to be applied to a certain user profile, user group, or even certain LDAP profile. This ensures the security of local network while providing Internet services to plenty of users.

High Availability (Hardware Redundancy)

Vigor3900 offers High Availability to prevent a single point of failure. The feature is based on the Common Address Redundancy Protocol (CARP). The network administrator can add a redundant Vigor3900 to the network as a standby router, in the events of failure of the main Vigor3900, the backup one can take over the traffic automatically, and reduce the downtime of the network.
