Overview

What This Product Does

The TL-ER5120 Gigabit Load Balance Broadband Router from TP-Link possesses exceptional data processing capabilities and a rich array of features including Load Balance, Access Control, DoS Defense, Bandwidth Control, and Session Limit. Suitable for small and medium-sized enterprises, the router can deliver high-speed connections to a large volume of client devices as part of a secure and easy-to-manage network.

Abundant Security Features

For defense against external threats, TL-ER5120 features automatic protection to detect and block Denial of Service (DoS) attacks such as TCP/UDP/ICMP Flooding, TCP Scanning, Ping of Death and other related threats. For better management of the internal network, TL-ER5120 allows administrators to set rules to block specific websites and limit staff access to specific services such as FTP, HTTP and SMTP. Captive Portal provides a convenient and secure method for guest authentication.

Superior Hardware

With a 64-bit network processor and 2Gbit DDRIII memory, TL-ER5120 is able to handle multiple tasks simultaneously while staying reliable and fast.

Intelligent Bandwidth Allocation

The TL-ER5120 features three freely interchangeable ports that can be set to either LAN or WAN, allowing the router to support up to four WAN ports to satisfy various internet access requirements. Intelligent Load Balancing can distribute data streams according to the bandwidth proportion of each WAN port to make full use of multi-line broadband. With IP-based Bandwidth Control and Session Limit functions, network administrators can flexibly manage network bandwidth to optimize usage.

Peace of Mind Whatever the Weather

Professional-standard lightning protection prevents electrical surges from penetrating your network equipment. Designed to withstand 4KV of electricity when well-grounded, this router ensures your network investments remain as safe as possible.
