5. 4. IP & MAC Binding
IP & MAC Binding enables you to bind a specific IP address to your network device’s MAC
address, and is also known as Address Resolution Protocol (ARP) Binding. It protects
your home network from ARP Spoofing, one kind of ARP attacks. By ARP Spoofing, an
attacker can modify and even stop your internet traffic. ARP Spoofing is often followed
by more serious cyber attacks. When you bind an IP address to your network device,
it has exclusive use of the IP address. The attacking device deliberately associating
its MAC address with the bound IP address is denied from accessing your network. To
keep your home network safe from ARP Spoofing, you can rely on IP & MAC Binding.
Prevent ARP spoofing.
1. Visit http://tplinkmodem.net, and log in with the password
you set for the router.
2. Go to Advanced > Security > IP & MAC Binding and enable IP
& MAC Binding.
3. Bind your device(s) according to your needs.
Done!

How can I
do that?
23
Chapter 5 Network Security
To bind the connected device(s)
1 ) Select the device(s) to be bound in the ARP List.
2 ) Click Bind to add to the Binding List.
To bind the unconnected device
1 ) Click Add.
2 ) Enter the MAC address and IP address that you want to
bind. If you don’t know your device’s MAC address, you
can use the Network Map (Basic > Network Map) to help
find it.
3 ) Select Enable This Entry and click Save.
Note:
1. To keep the IP & MAC Binding entries effective all the time, it is recommended
to use Address Reservation (Advanced > Network > LAN Settings) to
reserve the bound IP address to your device or set your device to the bound
IP address.
2. Your device has exclusive use of the IP address bound to its MAC address.
If you want to bind several IP addresses to your device's MAC address, just
add more binding entries.
Now you don’t need to worry about ARP spoofing.
Done!

NAT Forwarding
Modem router’s NAT (Network Address Translation) feature makes the devices in the
LAN use the same public IP address to communicate in the internet, which protects the
local network by hiding IP addresses of the devices. However, it also brings about the
problem that external host cannot initiatively communicate with the specified device in
the local network.
With forwarding feature the modem router can penetrate the isolation of NAT and
allows the external hosts in the internet to initiatively communicate with the devices in
the local network, thus to realize some special functions.
TP-Link modem router includes three forwarding rules. If two or more rules are set, the
priority of implementation from high to low is Virtual Servers, Port Triggering and DMZ.
This chapter contains the following sections:
• Share Local Resources over the Internet by Virtual Servers
• Open Ports Dynamically by Port Triggering
• Free Applications from Port Restriction by DMZ
• Translate Address and Port by ALG
49
Chapter 9 NAT Forwarding
9. 1. Share Local Resources over the Internet by
Virtual Servers
When you build up a server in the local network and want to share it over the internet,
Virtual Servers can realize the service and provide it for the internet users. At the same
time Virtual Servers can keep the local network safe as other services are still invisible
from the internet.
Virtual Servers can be used for setting up public services in your local network, such as
HTTP, FTP, DNS, POP3/SMTP and Telnet. Different service uses different service port.
Port 80 is used in HTTP service, port 21 in FTP service, port 25 in SMTP service and port
110 in POP3 service. Please verify the service port number before the configuration.
Share my personal website I’ve built in local network with my
friends through the internet.
For example, the personal website has been built in my home PC
(192.168.1.100). I hope that my friends can visit my website. The
PC is connected to the modem router with the WAN IP address
218.18.232.154.
Modem Router
WAN: 218.18.232.154
LAN
Home
Personal Website
1. Assign a static IP address to your PC, for example
192.168.1.100.
2. Visit http://tplinkmodem.net, and log in with the password
you set for the router.
3. Go to Advanced > NAT Forwarding > Virtual Servers, click
Add.
I want to:
How can I
do that?
50
Chapter 9 NAT Forwarding
4. Click Scan to select a service from the list to automatically
populate the appropriate port number in the External Port
and Internal Port fields. If the service is not listed, enter the
service manually, and enter the External Port number (e.g.
21) or a range of ports (e.g. 21-25). Leave the Internal Port
blank if it is the same as the External Port; or enter a specific
port number (e.g. 21) if the External Port is a single port. Here
we take HTTP as an example.
5. Enter the IP address of the PC running the service application
in the Internal IP field. Here is 192.168.1.100.
6. Select the corresponding protocol for the service application:
TCP, UDP, or All from the Protocol drop-down list.
7. Select Enable This Entry.
8. Click Save.
Tips:
1. You should verify the port number that the service needs.
2. You can add multiple port forwarding rules if you want to provide several
services in a modem router. Please note that the External Port cannot be
overlapped.
Users in the internet can enter http:// WAN IP: External Port (in
this example: http://218.18.232.154:80) to visit your personal
website.
Tips:
WAN IP should be a public IP address. For the WAN IP is assigned dynamically
by ISP, it is recommended to apply and register a domain name for the WAN
by DDNS, go to Set Up a Dynamic DNS Service Account for more information.
Then you can use http:// Domain Name: External Port to visit the website.
Done!
51
Chapter 9 NAT Forwarding
9. 2. Open Ports Dynamically by Port Triggering
Port Triggering can specify a trigger port and its corresponding external ports. When
a host in the local network initiates a connection to the trigger port, all the external
ports will be opened for subsequent connections. The modem router can record the IP
address of the host. When the data from the internet return to the external ports, the
modem router can forward them to the corresponding host. Port Triggering is mainly
applied to online games, VoIPs and video players. Common applications include MSN
Gaming Zone, Dialpad and Quick Time 4 players, etc.
Follow the steps below to configure the port triggering rules:
1. Visit http://tplinkmodem.net, and log in with the password you set for the router.
2. Go to Advanced > NAT Forwarding > Port Triggering and click Add.
3. Click Scan to select an application from the list to automatically populate the
default values into the appropriate fields. If you want to add an unlisted application,
manually enter the Application, Triggering Port, Triggering Protocol, External Port
and select the External Protocol.
4. Select Enable This Entry.
5. Click Save.
Note:
1. When the triggering connection is released, the corresponding opened ports will be closed.
2. Each rule can only be used by one host on the LAN at a time. The triggering connection of other hosts on the LAN
will be refused.
3. External Port ranges of different entries cannot overlap each other.
52
Chapter 9 NAT Forwarding
9. 3. Free Applications from Port Restriction by DMZ
When a PC is set to be a DMZ (Demilitarized Zone) host in the local network, it is totally
exposed to the internet. This can realize the unlimited bidirectional communication
between internal hosts and external hosts. The DMZ host becomes a virtual server with
all ports opened. When you are not clear about which ports to open in some special
applications, like IP camera and database software, you can set the PC to be a DMZ
host.
Note:
DMZ is more applicable in the situation that users are not clear about which ports to open. When it is
enabled, the DMZ host is totally exposed to the internet, which may bring some potential safety hazard. If
DMZ is not in use, please disable it in time.
Allow the home PC to join the internet online game without port
restriction.
For example, due to some port restriction, when playing the
online games, you can log in normally but cannot join a team
with other players. To solve this problem, set your PC as a DMZ
with all ports opened.
1. Assign a static IP address to your PC, for example
192.168.1.100.
2. Visit http://tplinkmodem.net, and log in with the password
you set for the router.
3. Go to Advanced > NAT Forwarding > DMZ.
4. Enable DMZ.
5. Enter the IP address 192.168.1.100 in the DMZ Host IP
Address field.
6. Click Save.
The configuration is completed. You’ve set your PC to a DMZ
host and now you can make a team to game with other players.

Chapter 9 NAT Forwarding
9. 4. Translate Address and Port by ALG
ALG (Application Layer Gateway) allows customized NAT (Network Address Translation)
traversal filters to be plugged into the gateway to support address and port translation
for certain application layer “control/data” protocols: FTP, TFTP, H225 etc. Enabling ALG
is recommended.
Visit http://tplinkmodem.net, and log in with the password you set for the router. Go to
Advanced > NAT Forwarding > ALG.
• IPSec Passthrough: If enabled, it allows IPSec (Internet Protocol Security) to
be tunneled through an IP network and passed through the router. IPSec uses
cryptographic security services to ensure private and secure communications over
IP networks.
• PPTP Passthrough: If enabled, it allows Point-to-Point sessions to be tunneled through
an IP network and passed through the router.
• Multicast ALG: If enabled, it allows Multicast clients and servers to transfer data via
NAT.
• UPnP ALG: If enabled, it allows UPnP (Universal Plug and Play) clients and servers to
transfer data via NAT.
• FTP ALG: If enabled, it allows FTP (File Transfer Protocol) clients and servers to transfer
data via NAT.
• TFTP ALG: If enabled, it allows TFTP (Trivial File Transfer Protocol) clients and servers
to transfer data via NAT.
• H225 ALG: If enabled, it allows H225 messages to be transferred via NAT.
