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-ER6020 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. 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.
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. For example: If the DMZ port of the Router is in WAN mode, the Hosts in the subnet of DMZ port can access the servers in Internet only when the Static Router rules permit. Note: In Non-NAT mode, all the NAT forwarding rules will be disabled.

The first entry in Figure 3-43 indicates: If there are packets being sent to a device with IP address of 211.162.1.0 and subnet mask of 255.255.255.0, the Router will forward the packets from WAN1 port to the next hop of 211.200.1.1. Application Example There is a network topology as the following figure shown: If the LAN port of TL-ER6020（with Non-NAT or Classic system mode）is connected to LAN1 with subnet of 192.168.0.0/24, while the LAN port of another Router R1 is connected to LAN2 with network of 192.
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.

Figure 5-4 Port Settings 6. Choose File → Properties → Settings on the Hyper Terminal window as Figure 5-5 shows, then choose VT100 or Auto detect for Emulation and click OK.
7. The DOS prompting “TP-LINK>” will appear after pressing the Enter button in the Hyper Terminal window as Figure 5-6 shows. Figure 5-6 Log in the Router 5.2 Interface Mode The CLI of TL-ER6020 offers two command modes: User EXEC Mode and Privileged EXEC Mode. User EXEC Mode only allows users to do some simple operations such as view the system information, while Privileged EXEC Mode allows you to manage and configure the Router. Thus different users have different privileges management.
Mode Accessing Path User EXEC Primary Mode mode Prompt once it is TP-LINK > Logout or Access the next mode Use the exit command to disconnect the Router (except that the Router is connected with the Router. connected through the Console port). Use the enable command to access Privileged EXEC mode.
2) enable - Enter the privileged mode exit - Exit the CLI (only for telnet) history - Show command history ip - Display or Set the IP configuration ip-mac - Display or Set the IP mac bind configuration sys - System manager user - User configuration Type a command and a question mark separated by space. If there are keywords in this command, all the keywords and their brief descriptions will display.
5.4 Command Introduction TL-ER6020 provides a number of CLI commands for users to manage the Router and user information. For better understanding, each command is followed by note which is the meaning of the command. 5.4.1 ip The ip command is used to view or configure the IP address and subnet mask of the interfaces. View command can be used in both User EXEC Mode and Privileged EXEC Mode while configuration function can be only used in Privileged EXEC Mode.
5.4.3 sys The sys command is used for system management, including Backup and Restore, Factory Default, Reboot, Firmware Upgrade and so on. Reboot the system. Y means TP-LINK # sys reboot This command will reboot system, Continue?[Y/N] YES, N means NO. Restore to factory default. Y TP-LINK # sys restore This command will restore system, Continue?[Y/N] means YES, N means NO. TP-LINK # sys export config Export the configuration file. Server address: [192.168.1.101]192.168.1.
● Pay special attention that the specified account must be with appropriate permissions since the functions such as export, import and firmware upgrade require read-write operation on FTP server. TP-LINK # sys import config Import the configuration file. Server address: [192.168.1.101] The steps are as the above item shown. Username: [admin] Password: [admin] File name: [config.bin] Try to get the configuration file < config.bin > ...
