Product Features

High-Performance Dual-WAN Routing

Features 1 dedicated Gigabit WAN port and 3 flexible Gigabit WAN/LAN ports, allowing for load balancing and automatic failover to ensure stable, high-speed internet access.

Up to 150,000 Concurrent Sessions

Supports high-volume traffic and connections, making it suitable for environments with large user bases or high session concurrency.

Advanced VPN Support

Supports up to 100 IPsec VPN tunnels and 50 PPTP/L2TP VPN connections, allowing secure remote access and site-to-site connectivity using robust encryption protocols such as AES256, SHA1, and MD5.

Comprehensive Traffic Management

IP-based bandwidth control and session limiting help manage network resources and ensure fair usage, especially in environments with diverse or heavy bandwidth consumption.

Intelligent Load Balancing

Automatically distributes traffic across multiple WAN connections to maximize performance and ensure consistent uptime.

Full Spectrum of Security Features

Built-in defenses include DoS protection, IP-MAC binding, SPI firewall, ARP inspection, and access control policies to guard against both external and internal threats.

Centralized Management and Monitoring

Offers web-based configuration, SNMP, system logging, diagnostics, and remote management options for efficient control of your network environment.
