TP-LINK TL-ER5120 Load Balance Broadband Routers NAT Setup

Category : TL-ER5120

NAT (Network Address Translation) is the translation between private IP and public IP,

which allows private network users to visit the public network using private IP addresses.

With the explosion of the Internet, the number of available IP addresses is not enough.

NAT provides a way to allow multiple private hosts to access the public network with one public IP at the same time,

which alleviates the shortage of IP addresses.

Furthermore, NAT strengthens the LAN (Local Area Network) security of the network since

the address of LAN host never appears on the Internet.

NAT Setup

On this page, you can set up the NAT function.

Choose the menu Advanced→NAT→NAT Setup to load the following page.

TP-LINK TL-ER5120 Load Balance Broadband Routers Port VLAN Configuration

Category : TL-ER5120

A VLAN (Virtual Local Area Network) is a network topology configured according to a logical scheme rather than the physical layout,

which allows you to divide the physical LAN into multiple logical LANs so as to control the communication among the ports.

The VLAN function can prevent the broadcast storm in LANs and enhance the network security.

By creating VLANs in a physical LAN, you can divide the LAN into multiple logical LANs,

each of which has a broadcast domain of its own.

Hosts in the same VLAN communicate with one another as if they are in a LAN.

However, hosts in different VLANs cannot communicate with one another directly.

Therefore, broadcast packets are limited in a VLAN.

TL-ER5120 provides the Port VLAN function,

which allows you to create multiple logical VLANs for the LAN ports based on their port numbers.

Egress Limit: Specify whether to enable Egress Limit feature.

Egress Rate: Specify the limit rate for the egress packets.

The first entry in Figure indicates: The Ingress and Egress Limits are enabled for port 1.

The Ingress mode is Flood while the Ingress and Egress Rates are 1Mbps.

That is, the receiving rate for the ingress packets of Flood mode will not exceed 1Mbps,

and the transmitting rate for all the egress packets will not exceed 1Mbps.


TP-LINK TL-ER5120 Load Balance Broadband Routers Port Mirror Configuration

Category : TL-ER5120

Port Mirror, the packets obtaining technology, functions to forward copies of packets

from one/multiple ports (mirrored port) to a specific port (mirroring port).

Usually, the mirroring port is connected to a data diagnose device,

which is used to analyze the mirrored packets for monitoring and troubleshooting the network.
