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

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

4.7.3 Dynamic DNS
DDNS (Dynamic DNS) service allows you to assign a fixed domain name to a dynamic WAN IP
address, which enables the Internet hosts to access the router or the hosts in LAN using the domain
names.
-92-
Download from Www.Somanuals.com. All Manuals Search And Download.
As many ISPs use DHCP to assign public IP addresses in WAN, the public IP address assigned to the
client is unfixed. In this way, it’s very difficult for other clients to get the latest IP address of this client
for access.
DDNS (Dynamic DNS) server provides a fixed domain name for DDNS client and maps its latest IP
address to this domain name. When DDNS server works, DDNS client informs the DDNS server of the
latest IP address, the server will update the mappings between the domain name and IP address in
DNS database. Therefore, the users can use the same domain name to access the DDNS client even
if the IP address of the DDNS client has changed. DDNS is usually used for the Internet users to
access the private website and FTP server, both of which are established based on Web server.
The router, as a DDNS client, cannot provide DDNS service. Prior to using this function, be sure you
have registered on the official websites of DDNS service providers for username, password and
domain name. TL-R480T+ router offers PeanutHull DDNS client, Dyndns DDNS client, NO-IP DDNS
client and Comexe DDNS client.
The Dynamic DNS can be implemented on DynDNS DDNS, No-IP DDNS, Peanuthull DDNS and
Comexe DDNS pages.

Appendix B FAQ
Q1. What can I do if I cannot access the web-based configuration page?
1. For the first login, please try the following steps:
1) Make sure the cable is well connected to the LAN port of the router. The corresponding LED
should flash or be solid light.
2) Make sure the IP address of your PC is set in the same subnet addresses of the router. It’s
recommended to set your PC to get the IP address automatically. Then the router with DHCP
enabled can automatically assign the IP address to your PC. If you want to configure your PC
manually, please set 192.168.0.x ("x" is any number between 2 to 254) for the IP address and
255.255.255.0 for the Subnet Mask.
3) Test the connection between your PC and TL-R480T+ via Ping command.
4) If you still cannot access the configuration page, please restore your router to its factory default
settings and try to log in again.
2. If your management port has been changed, please log into the router with the new address, such
3. If you had successfully logged into the router before, but now you cannot access the router. It’s
quite possible that the configuration of your router has been changed by others, especially when
the Remote Web Management function is enabled. You’re recommended to restore your router
and reconfigure the management port number and the username as well as the password for your
network security.
4. If you cannot access the router even after restoring the router to its defaults, or your login is
dropped down just after a while, it’s quite possible that your router is attacked by ARP cheating.
It’s recommended to locate and quarantine the source of ARP cheating so as to prevent your
network from the attacks.
5. Check to see if you have configured the proxy server for IE browser. If so, please disable the IE
proxy server first.
Q2: What can I do if I forgot the username and the password of the router? How to restore the
router to its factory default settings?
You can restore the router to its factory default settings by the Reset button. It must be noted that once
the router is reset, all the current configuration settings will be lost.
With the router powered on, use a pin to press and hold the
button (about 5 seconds). If the SYS
Reset
LED is flashing 5 times in high frequency, release the
button. It means the router is restored

Q3: What can I do if the router with the remote management function enabled cannot be
accessed by the remote computer?
1. Make sure that the IP address of the remote computer is in the subnet allowed to remotely access
the router.
2. If the router’s management port has been modified, please log into the router with the new
address, such as http://192.168.0.1:XX (“XX” is the new management port number).
3. Check to see if the management port has been mapped to the service port of the LAN host in the
Virtual Server function. If so, you should make a change in the router’s management port or virtual
server’s service port.
4. Make sure that the NAT DMZ service is disabled.
Q4: Some function of the router need to define the IP address subnet with Subnet Mask. What
are the common values of the Subnet Mask?
Subnet Mask is a 32-bit binary address used to distinguish the network address and the host address.
When dividing the network, the different Subnet Mask defines different subnet, and each subnet owns
different number of hosts.
After conversed from 32-bit binary address to decimal address, the common Subnet Mask values can
be 8 (which represents the default Subnet Mask value of class A: 255.0.0.0), 16 (which represents the
default Subnet Mask value of class B: 255.255.0.0), 24 (which represents the default Subnet Mask
value of class C: 255.255.255.0) or 32 (which represents the default Subnet Mask value of class D:
255.255.255.255).
