TP-LINK Gigabit Load Balance
Broadband Router
TL-ER5120
The TL-ER5120 Gigabit Load Balance Broadband Router from TP-LINK possesses excellent data processing
capabilities and multiple powerful functions including Load Balance, Access Control, IM/P2P Blocking,
DoS Defense, Bandwidth Control, Session Limit, PPPoE Server and so on, which consumedly meet the
needs of small and medium enterprises, hotels and communities with large volumes of users demanding
an ecient and easy-to-manage network with high security.
Abundant Security Features
For defense against external threats, TL-ER5120 features an 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. Moreover, this router oers a hardware DMZ port, which allows you to setup public servers
without exposing your internal network, to avoid attacks from external threats. For better management of
the internal network, TL-ER5120 allows administrators to set rules to block specic web sites and IM/P2P
applications with just one-click, and restrict sta to use specic services such as FTP, HTTP and SMTP.

Better Reasonable Management
By setting PPPoE Server to allocate PPPoE account to the private network users, the router only allows the
users with legal account and passed the authentication to access the Internet via. Cooperating with
IP-based Bandwidth Control, it is capable to conne the bandwidth usage of certain PPPoE account.
Moreover, the E-Bulletin function is able to release bulletin in the form of webpage to certain user groups
periodically, which noties the users about the expiration date of the PPPoE account. With the above
features, the router will prioritize dierent users in surfer jurisdiction for a better reasonable management.
Optimizing Bandwidth Usage
The TL-ER5120 features three free changeable 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 through one device.
The Intelligent Load Balancing function can distribute data streams according to the bandwidth propor-
tion of every WAN port to raise the utilization rate of multi-line broadband. With IP-based Bandwidth
Control and Session Limit functions, network administrators can exibly manage network bandwidth to
optimize bandwidth usage.
Safety Minded Enterprise Investments
Professional lightning protection technology is designed to prevent electrical surges from penetrating the
interior of the electrical equipment and is discharged harmlessly into the Earth. This router is designed to
prevent lightning up to 4Kv in the well-grounded connection conditions. This feature ensures that
networking infrastructure investments remain as safe as possible from one of mother nature's more
violent situations.
