TRENDnet TWG-431BR – Gigabit Multi-WAN VPN Business Router

TRENDnet’s Gigabit Multi-WAN VPN Business Router, model TWG-431BR, features internet WAN load balancing, a network fail-safe backup, and encrypted Virtual Private Network (VPN) access for remote users. Improve peak-network-loading performance and eliminates network downtime with the use of the VPN router’s multiple WAN ports. Smooth network loading, minimize network downtime, and allow employees to access your network from the Internet—all with a single router. The VPN router features advanced management, high availability, QoS, VLAN, VPN, and other capabilities to ensure optimal performance, scalability, and protection of your network. Advanced SPI, NAT and SNAT protects against Internet attacks.

The TWG-431BR comes fully integrated with Router Limits’ comprehensive web management system, designed to give users more control over the activity on their network. Manage screen time, filter content, track web use and browsing history, as well as device level controls and more. Router Limits’ software is also available for mobile devices, providing you better management of your connected network.

The latest software upgrade adds support for DPI and speed test. DPI analyzes data traffic and provides more detailed information on specific devices or users, such as bandwidth usage, content being downloaded or viewed, apps that are used, and more. This allows both IT administrators at work and parents in the home to better monitor and manage network traffic. Conveniently run speed tests remotely between your TRENDnet router and ISP to check your Internet connection speeds for connectivity or bandwidth issues.


Connect up to four separate WAN internet connections to efficiently load-balance traffic by distributing network traffic to the best available link.

VPN Router

The VPN router creates an encrypted VPN tunnel to access local area network resources remotely using IPSec, PPTP, L2TP w/ IPsec, and SSL VPN protocols.

High Availability

Group multiple TWG-431BR routers together to create a high availability network with router redundancy to minimize downtime.
