Chapter 3 Configuration 3.1 Network 3.1.1 Status The Status page shows the system information, the port connection status and other information related to this Router. Choose the menu Network→Status to load the following page.
Figure 3-1 Status 3.1.2 System Mode The TL-ER5120 Router can work in three modes: NAT, Non-NAT and Classic. If your Router is hosting your local network’s connection to the Internet with a network topology as the Figure 3-2 shown, you can set it to NAT mode.
Figure 3-2 Network Topology - NAT Mode If your Router is connecting the two networks of different areas in a large network environment with a network topology as the Figure 3-3 shown, and forwards the packets between these two networks by the Routing rules, you can set it to Non-NAT mode. Figure 3-3 Network Topology – Non-NAT Mode If your Router is connected in a combined network topology as the Figure 3-4 shown, you can set it to Classic Mode.
Figure 3-4 Network Topology – Classic Mode Choose the menu Network→System Mode to load the following page. Figure 3-5 System Mode You can select a System Mode for your Router according to your network need. z NAT Mode NAT (Network Address Translation) mode allows the Router to translate private IP addresses within internal networks to public IP addresses for traffic transport over external networks, such as the Internet. Incoming traffic is translated back for delivery within the internal network.
source IP address can be transported by NAT, whereas the packet with 20.31.76.80 as its source IP address will be dropped. z Non-NAT Mode In this mode, the Router functions as the traditional Gateway and forwards the packets via routing protocol. The Hosts in different subnets can communicate with one another via the routing rules whereas no NAT is employed.

3.1.5 DMZ DMZ (Demilitarized Zone) is a network which has fewer default firewall restrictions than the LAN does. TL-ER5120 provides a DMZ port to allow all the local hosts connected to this port to be exposed to the Internet for some special-purpose services, such as such as Internet gaming and video-conferencing. The DMZ physical port can work in Public mode and Private mode. In Public mode, the DMZ port allows the Hosts in DMZ to directly communicate with Internet via routing mode using public IP address.
Choose the menu Network→DMZ→DMZ to load the following page. Figure 3-18 DMZ The following items are displayed on this screen: ¾ DMZ Status: Activate or inactivate this entry.

Set the MAC Address for LAN port: In a complex network topology with all the ARP bound devices, if you want to change to use TL-ER5120 instead of the current router in a network node, you can just set the MAC address of TL-ER5120 ‘s LAN port the same to the MAC address of the previous router, which can avoid all the devices under this network node to update their ARP binding tables.
to apply. Note: To avoid a conflict of MAC address on the LAN, it’s not allowed to set the MAC address of the Router’s LAN port to the MAC address of the current management PC. 3.1.7 Switch Some basic switch port management functions are provided by TL-ER5120, which facilitates you to monitor the traffic and manage the network effectively. 3.1.7.1 Statistics Statistics screen displays the detailed traffic information of each port, which allows you to monitor the traffic and locate faults promptly.
Unicast: Displays the number of normal unicast packets received or transmitted on the port. Broadcast: Displays the number of normal broadcast packets received or transmitted on the port. Pause: Displays the number of flow control frames received or transmitted on the port. Multicast: Displays the number of normal multicast packets received or transmitted on the port. Undersize: Displays the number of the received frames (including error frames) that are less than 64 bytes long.

Mode: Select the mode for the port mirror function. Options include: z Ingress: When this mode is selected, only the incoming packets sent by the mirrored port will be copied to the mirroring port.
The entry in Figure 3-21 indicates: The outgoing packets sent by port 1, port 2, port 3 and port 5 (mirrored ports) will be copied to port 4 (mirroring port). Tips: If both the mirrored port and the mirroring port are the LAN ports, these two LAN ports should be in the same Port VLAN. For example, if port 3 (the mirroring port) and port 4 (the mirrored port) are the LAN ports, the Port Mirror function can take effect only when port 3 and port 4 are in the same Port VLAN.
Figure 3-22 Rate Control The following items are displayed on this screen: ¾ Rate Control Port: Displays the port number. Ingress Limit: Specify whether to enable the Ingress Limit feature.

3.1.7.6 Port VLAN 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.

The data packets are transmitted from WAN1 port. DMZ Forwarding and this entry are both activated. Note: One-to-One NAT entries take effect only when the Connection Type of WAN is Static IP. Changing the Connection type from Static IP to other ones will make the entries attached to the interface disabled. 3.3.1.
The first entry in Figure 3-30 indicates that: This is a Multi-Nets NAT entry named tplink1. The subnet under the LAN port of the Router is 192.168.2.0/24 and this entry is activated. After the corresponding Static Route entry is set, the hosts within this subnet can access the Internet through the Router via NAT. Note: ● Multi-Nets NAT entry takes effect only when cooperating with the corresponding Static Route entries.

The first entry in Figure 3-42 indicates: If there are packets being sent to a device with IP address of 172.31.70.28 and subnet mask of 255.255.255.0, the Router will forward the packets from WAN1 port to the next hop of 116.10.1.254. Application Example There is a network topology as the following figure shown: If the LAN port of TL-ER5120（with Non-NAT or Classic system mode）is connected to LAN1 with subnet of 192.168.0.
The distance of RIP refers to the hop counts that a data packet passes through before reaching its destination, the value range of which is 1–15. It means the destination cannot be reached if the value is more than 15. Optimal path indicates the path with the fewest hop counts. RIP exchanges the route information every 30 seconds by broadcasting UDP packets.
Authentication: network situation, and the password should not be more than 15 characters. All Interfaces: Here you can operate all the interfaces in bulk. All the interfaces will not apply RIP if “Enable” option for All Interfaces is selected. ¾ List of RIP After RIP is enabled, the information of RIP forwarding the packets received by the Router will be displayed in the list. The first entry in Figure 3-43 indicates: when receiving packets with destination IP is 116.10.20.
