4.3.4 MAC Address
The MAC (Media Access Control) address, as the unique identifier of the router in network, does not
need to be changed commonly.
Set the MAC Address for LAN port:
In a complex network topology with all the ARP bound devices, if you want to use TL-R480T+ instead
of the current router in a network node, you can just set the MAC address of TL-R480T+’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.
Set the MAC Address for WAN port:
In the condition that your ISP has bound the account and the MAC address of the dial-up device, if you
want to change the dial-up device to be TL-R480T+, you can just set the MAC address of TL-R480T+’s
WAN port the same to the MAC address of the previous dial-up device for a normal Internet
connection.

mirroring port.
Select the Mirroring Port to which the traffic is copied. Only one port can
be selected as the mirroring port.
Select the Mirrored Port from which the traffic is mirrored. One or multiple
ports can be selected as the mirrored ports.
The entry in Figure 4-16 indicates: The outgoing packets sent by port 1, port 2, port 3 and port 5
(mirrore
d 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.

4.3.5.6 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. 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-R480T+ provides the Port VLAN function, which allows you to create multiple logical VLANs for the
LAN ports based on their port numbers.

4.5.1 NAT
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.

Application Example
Network Requirements
LAN1 is under the router and it uses network segment 192.168.0.0 /24. LAN2 and LAN3 are under a
layer 3 switch and they use network segments 192.168.2.0 /24 and 192.168.3.0 /24 respectively. The IP
address of the cascading LAN port between the layer 3 switch and the router is 192.168.0.2. Now the
hosts within LAN1 desire to access the hosts within LAN2 and LAN3.
The network topology is shown as the following:
Configuration procedure
1. On the Static Route page, add a static routing rule for LAN2 with destination address 192.168.2.0
(LAN2’s IP address) and next hop address 192.168.0.2 (IP address of the cascading LAN port) as
shown in the following figure. Then click the <Add> button.

2. Add a static routing rule for LAN3 by referring to step 1.
The static routing rules are shown in the following figure.
4.6 Firewall
4.6.1 Anti ARP Spoofing
ARP (Address Resolution Protocol) is used to analyze and map 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, where 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.
4.6.1.1 IP-MAC Binding
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.
-73-
Figure 4-39 IP-MAC Binding
The following items are displayed on this screen:
General
It is recommended to check all the options. You should import the IP and MAC address of the host
to List of IP-MAC Binding 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.
Check the box before Enable ARP Logs, and the router will send ARP logs to the specified server.

Enter the start and the end IP addresses in the Scanning IP Range field. Then click the <Scan> button,
the router will scan all the active hosts within the scanning range and display the result in the list.
The entries displayed on the List of Scanning Result do not mean the IP and MAC addresses are
already bound. The current status for the entry will display in the “Status” field.
--- Indicates that the IP and MAC address of this entry is not bound and may be
replaced by error ARP information.

The PPPoE configuration can be implemented on General, IP Address Pool, Account, Exceptional
IP and List of Account pages.
