TL-ER5120 is a high-performance Internet cafe router with multiple WAN ports launched by TP-LINK. It uses a 64-bit network dedicated processor, is equipped with 128MB DDRII high-speed memory, has powerful hardware processing performance, and supports multiple WAN ports, load balancing, Line backup, intelligent bandwidth control, ARP attack protection, DoS attack protection, access control strategy, URL filtering, game acceleration and other rich features are suitable for deployment in Internet cafes, communities, hotels and other network environments to form high performance, high stability, and high Secure network.

high performance

TL-ER5120 provides 1 10/100M WAN port, 1 10/100M LAN port, 3 10/100M WAN/LAN configurable ports, using a 64-bit network dedicated processor with a main frequency of 500MHz, combined with 128MB/533MHz The high-speed DRRII memory ensures that the TL-ER5120 has high-speed data processing capabilities and supports wire-speed forwarding between the LAN port and the WAN port.

High stability

TL-ER5120 adopts innovative heat-conducting natural heat dissipation, fanless design, built-in high-quality switching power supply, wide operating voltage range, effectively preventing unstable problems caused by voltage fluctuations, and ensuring normal startup and stable operation of the equipment in a low-voltage environment; external Using 1U steel shell, 19-inch standard frame design, fully guarantee the long-term stable operation of the whole machine.

High security

TL-ER5120 has a powerful attack protection function, which can not only defend against ARP attacks and spoofing and virus attacks from the local area network, but also against ARP viruses and DoS attacks from the Internet, and fully guarantee the long-term stable and safe operation of the Internet cafe network.

Anti-LAN attack: TL-ER5120 supports IP/MAC binding to hosts in the LAN, which effectively prevents ARP attacks in the LAN; supports a free ARP packet timing sending mechanism, effectively avoids ARP spoofing in the LAN, and completely eliminates ARP attacks in the LAN . TL-ER5120 has built-in advanced firewall and filtering rules. It not only supports filtering rules based on IP, MAC, and URL, but users can also customize virus types according to protocols and port numbers, and perform two-way detection and filtering on data packets, effectively preventing Nimda and shock waves. Virus attacks such as, Trojan horses, etc. provide reliable LAN security for Internet cafes.

Anti-WAN attack: TL-ER5120 supports IP/MAC binding to the gateway connected to the WAN port, which effectively prevents ARP attacks from the WAN; it also provides rich attack protection such as scanning, DoS, and suspicious packets, which can effectively Detect and block IP address spoofing, source routing attacks, IP/port scanning, DoS and other network attacks from the WAN.

High flexibility

Flexible access mode: TL-ER5120 provides 3 WAN/LAN configurable ports. By default, the device works in dual WAN port mode. Users can flexibly configure the number of WAN ports of the router according to actual needs to meet multi-line access requirements ; At the same time, it also provides a complete flow balance strategy and line backup function to easily expand network bandwidth and ensure stable access; TL-ER5120 supports PPPoE, dynamic IP, static IP and L2TP multiple access methods, and can adapt to ADSL, fiber, and residential Various access requirements such as broadband.

Flexible bandwidth management: support intelligent bandwidth control function, can flexibly enable bandwidth control strategy according to the actual bandwidth utilization rate, can carry out two-way bandwidth control for each host (IP) in the network, effectively restrain the excessive occupation of P2P applications such as BT and Thunder Bandwidth, to avoid the problems of online game cards and slow Internet speed, and to ensure the smooth flow of the network at all times; support the game acceleration function to ensure the smooth flow of the game; support the connection limit function, effectively preventing the excessive use of bandwidth by P2P software such as BT and Thunder.

Flexible equipment configuration management: TL-ER5120 supports the import and export of configuration files, which greatly shortens the configuration time; at the same time, it adopts the all-Chinese WEB management interface, supports remote management, and provides a variety of system detection tools and rich log functions, and equipment management and maintenance are flexible; Support the modification of MAC address of WAN and LAN ports, flexible and convenient network formation and equipment upgrade.

Flexible function setting: TL-ER5120 supports one-to-one NAT function, which can easily allocate the WAN IP address to a specific server and avoid the use of complicated virtual server rules. Support ARP scanning and import function, easily realize the whole network ARP binding.
