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-ER604W Router can work in three modes: NAT, Non-NAT and Classic.
-9-
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
-10-
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. 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
-11-
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.
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-ER604W provides two adjustable 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.

Provider).
Tips:
It’s allowed to set the IP addresses of both the 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.

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-ER604W provides the Port VLAN function, which allows you to create multiple logical VLANs for
the LAN ports based on their port numbers.

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.

3.4.5 Routing
3.4.5.1 Static Route
Routing is the process of selecting optimized paths in a network along which to send network traffic.
Static Route is a kind of special routing configured by the administrator, which is simple, efficient, and
reliable.
Commonly used in small-sized network with fixed topology, Static Route does not change along with
the network topology automatically. The administrator should modify the static route information
manually as long as the network topology or link status is changed.

The first entry in Figure 3-47 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-ER604W（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 192.168.2.0/24. Meanwhile, the WAN ports of the two routers are interconnected and within the
same network. Now a host under TL-ER604W and within network of LAN1 desires to communicate
with the host within network of LAN2.
You can set a Static Route entry: Enter the WAN IP address of R1 (116.31.88.16) in the Next Hop field
on the Static Route page of TL-ER604W as the following figure shown, then click the <Add> button to
save the entry.
3.4.5.2 RIP
RIP (Routing Information Protocol) is a dynamic route protocol using distance vector algorithm to select
the optimal path. With features of easy configuration, management and implementation, it is widely used
in small and medium-sized networks such as the campus network.
-79-
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. If one Router has not sent route information
in 180 seconds, the RIP of the other routers would set the distance to this Router into infinity and delete
the corresponding information from route table.
RIP develops from initial RIPv1 to RIPv2 gradually. Compared with RIPv1, RIPv2 supports VLSM
(Variable Length Subnet Mask), simple plain text authentication, MD5 cryptograph authentication, CIDR
(Classless Inter-Domain Routing) and multicast.
TL-ER604W supports both RIPv1 version and RIPv2 version, thus you can configure the RIP version
based on the actual need to improve the network performance.

3.5 Firewall
3.5.1 Anti ARP Spoofing
ARP (Address Resolution Protocol) is used for analyzing and mapping IP addresses to the
corresponding MAC addresses so that packets can be delivered to their destinations correctly.
ARP functions to translate the IP address into the corresponding MAC address and maintain an ARP
Table in which the latest used IP address-to-MAC address mapping entries are stored. ARP protocol
can facilitate the Hosts in the same network segment to communicate with one another or access to
external network via Gateway. However, since ARP protocol is implemented with the premise that all
the Hosts and Gateways are trusted, there are high security risks during ARP Implementation
Procedure in the actual complex network.
The attacker may send the ARP spoofing packets with false IP address-to-MAC address mapping
entries, and then the device will automatically update the ARP table after receiving wrong ARP
packets, which results in a breakdown of the normal communication. Thus, ARP defense technology is
generated to prevent the network from this kind of attack.
3.5.1.1
IP-MAC Binding functions to bind the IP address, MAC address of the host together and only allows the
Hosts matching the bound entries to access the network.
Choose the menu Firewall→Anti ARP Spoofing→IP-MAC Binding to load the following page.
IP-MAC Binding
-82-
Figure 3-50 IP-MAC Binding
The following items are displayed on this screen:
¾ General
It is recommended to check all the options. You should import the IP and MAC address of the host to
IP-MAC Binding List and enable the corresponding entry before enabling “Permit the packets
matching the IP-MAC Binding entries only”.
When suffered ARP attack, the correct ARP information will be sent to the device suffering attack
initiatively by GARP (Gratuitous ARP) packets, thus the error ARP information of the device will be
replaced. You can set the packets sending rate in the Interval field.
With the box before Enable ARP Logs checked, the Router will send ARP logs to the specified
server. The IP address of server is the Server IP set on 3.8.7 Logs.
