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.
-9-
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.
-10-
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.
-11-
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. However, the
Router will drop all the packets whose source IP addresses are in different subnet of LAN port. For
example: If the LAN port of the Router is set to 192.168.0.1 for IP address and 255.255.255.0 for the
Subnet Mask, then the subnet of LAN port is 192.168.0.0/24. The packet with 192.168.0.123 as its
-12-
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. 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.
z Classic Mode
It's the combined mode of NAT mode and Non-NAT mode. In Classic mode, the Router will first
transport the packets which are compliant with NAT forwarding rules and then match the other packets
to the static routing rules. The matched packets will be transmitted based on the static routing rules
and the unmatched ones will be dropped. In this way, the Router can implement NAT for the packets
without blocking the packets in the different subnet of the ports.
3.1.3 WAN
3.1.3.1 WAN Mode
TL-ER5120 provides four available WAN ports. You can set the number of WAN ports on this page.
Choose the menu Network→WAN→WAN Mode to load the following page.

Select the total number of WAN ports you prefer to use.
And the Router will adjust the physical ports
accordingly, which can be illustrated on the following
-13-
port sketch.
Note:
1) By default, TL-ER5120 is set to work in the mode of dual WAN ports.
2) Any change to the number of WAN ports may lead to a loss of current configurations. Please be
sure to backup your configurations in advance.
3) The DMZ port will not be available if four WAN ports are enabled.
3.1.3.2 WAN1
TL-ER5120 provides the following six Internet connection types: Static IP, Dynamic IP, PPPoE/Russian
PPPoE, L2TP/Russian L2TP, PPTP/Russian PPTP and BigPond. To configure the WAN, please first
select the type of Internet connection provided by your ISP (Internet Service Provider).
Tips:
● It’s allowed to set the IP addresses of multiple WAN ports within the same subnet. However, to
guarantee a normal communication, make sure that the WAN ports can access the same network,
such as Internet or a local area network.
● The amount of tab pages for WAN port varies with the number of the WAN ports. For the
configurations of the other WAN ports, please refer to the instructions of WAN1.
Choose the menu Network→WAN→WA N1 to load the configuration page.
