Network Security

This chapter guides you on how to protect your home network from cyber attacks and unauthorized users by implementing these three network security functions. You can protect your home network against DoS (Denial of Service) attacks from flooding your network with server requests using DoS Protection, block or allow specific client devices to access your network using Access Control, or you can prevent ARP spoofing and ARP attacks using IP & MAC Binding.

It contains the following sections:

• Protect the Network from Cyber Attacks

• Access Control

• IP & MAC Binding

Chapter 11

Network Security

11. 1. Protect the Network from Cyber Attacks

The SPI (Stateful Packet Inspection) Firewall and DoS (Denial of Service) Protection protect the router from cyber attacks.

The SPI Firewall can prevent cyber attacks and validate the traffic that is passing through the router based on the protocol. This function is enabled by default, and it’s recommended to keep the default settings.

DoS Protection can protect your home network against DoS attacks from flooding your network with server requests. Follow the steps below to configure DoS Protection.

1. Visit http://tplinkwifi.net, and log in with your TP-Link ID or the password you set for

the router.

2. Go to Advanced > Security > Firewall & Dos Protection.

3. Enable DoS Protection.

4. Set the level (Off, Low, Middle or High) of protection for ICMP-FLOOD Attack

Filtering, UDP-FlOOD Attack Filtering and TCP-SYN-FLOOD Attack Filtering.

• ICMP-FLOOD Attack Filtering - Enable to prevent the ICMP (Internet Control Message Protocol) flood attack.

• UDP-FlOOD Attack Filtering - Enable to prevent the UDP (User Datagram Protocol) flood attack.

• TCP-SYN-FLOOD Attack Filtering - Enable to prevent the TCP-SYN (Transmission Control Protocol-Synchronize) flood attack.

Tips:

The level of protection is based on the number of traffic packets. The protection will be triggered immediately

when the number of packets exceeds the preset threshold value (the value can be set on Advanced > System

Tools > System Parameters > DoS Protection Level Settings), and the vicious host will be displayed in the Blocked

DoS Host List.

Chapter 12

NAT Forwarding

The router’s NAT (Network Address Translation) feature makes devices on the LAN use the same public IP address to communicate with devices on the internet, which protects the local network by hiding IP addresses of the devices. However, it also brings about the problem that an external host cannot initiatively communicate with a specified device on the local network.

With the forwarding feature the router can penetrate the isolation of NAT and allows devices on the internet to initiatively communicate with devices on the local network, thus realizing some special functions.

The TP-Link router supports four forwarding rules. If two or more rules are set, the priority of implementation from high to low is Virtual Servers, Port Triggering, UPNP and DMZ.

It contains the following sections:

• Share Local Resources on the Internet by Virtual Servers

• Open Ports Dynamically by Port Triggering

• Make Applications Free from Port Restriction by DMZ

• Make Xbox Online Games Run Smoothly by UPnP

Chapter 12

NAT Forwarding

12. 1. Share Local Resources on the Internet by Virtual Servers

When you build up a server on the local network and want to share it on the internet, Virtual Servers can realize the service and provide it to 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 on your local network, such as HTTP, FTP, DNS, POP3/SMTP and Telnet. Different services use different service ports. 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.

I want to:

How can I do that?

Share my personal website I’ve built in local network with my friends through the internet.

For example, the personal website has been built on my home

PC (192.168.0.100). I hope that my friends on the internet can visit my website in some way. The PC is connected to the router with the WAN IP address 218.18.232.154.

Personal Website

Home

1. Assign a static IP address to your PC, for example

192.168.0.100.

2. Visit http://tplinkwifi.net, and log in with your TP-Link ID or the password you set for the router.

3. Go to Advanced > NAT Forwarding > Virtual Servers.

Router

INTERNET

WAN: 218.18.232.154LAN

4. Click Add. Click View Existing Services and select HTTP. The

External Port, Internal Port and Protocol will be automatically

filled in. Enter the PC’s IP address 192.168.0.100 in the

Internal IP field.

5. Click OK.

Chapter 12

Tips:

• It is recommended to keep the default settings of Internal Port and Protocol if you are

not clear about which port and protocol to use.

• If the service you want to use is not in the Service Type, you can enter the

corresponding parameters manually. You should verify the port number that the service needs.

• You can add multiple virtual server rules if you want to provide several services in a

router. Please note that the External Port should not be overlapped.

NAT Forwarding

Done!

Users on the internet can enter http:// WAN IP (in this example: http:// 218.18.232.154) to visit your personal website.

Tips:

• The WAN IP should be a public IP address. For the WAN IP is assigned dynamically by

the ISP, it is recommended to apply and register a domain name for the WAN referring to Set Up a Dynamic DNS Service Account. Then users on the internet can use

http:// domain name to visit the website.

• If you have changed the default External Port, you should use

http:// WAN IP: External Port or http:// domain name: External Port to visit the website.

12. 2. Open Ports Dynamically by Port Triggering

Port Triggering can specify a triggering port and its corresponding external ports. When a host on the local network initiates a connection to the triggering port, all the external ports will be opened for subsequent connections. The router can record the IP address of the host. When the data from the internet return to the external ports, the router can forward them to the corresponding host. Port Triggering is mainly applied to online games, VoIPs, video players and common applications including MSN Gaming Zone, Dialpad and Quick Time 4 players, etc.

Follow the steps below to configure the Port Triggering rules:

1. Visit http://tplinkwifi.net, and log in with your TP-Link ID or the password you set for the router.

2. Go to Advanced > NAT Forwarding > Port Triggering and click Add.

Chapter 12

NAT Forwarding

3. Click View Existing Applications, and select the desired application. The Triggering

Port, External Port and Protocol will be automatically filled in. The following picture

takes application MSN Gaming Zone as an example.

4. Click OK.

Tips:

• You can add multiple port triggering rules according to your network need.

• The triggering ports can not be overlapped.

• If the application you need is not listed in the Existing Applications list, please enter the parameters manually. You

should verify the external ports the application uses first and enter them into External Port field according to the

format the page displays.

12. 3. Make Applications Free from Port Restriction

by DMZ

When a PC is set to be a DMZ (Demilitarized Zone) host on the local network, it is totally exposed to the internet, which 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, such as IP camera and database software, you can set the PC to be a DMZ host.

Chapter 12

Note:

When DMZ is enabled, the DMZ host is totally exposed to the internet, which may bring some potential safety hazards. If

DMZ is not in use, please disable it in time.

NAT Forwarding

I want to:

How can I do that?

Make the home PC join the internet online game without port restriction.

For example, due to some port restriction, when playing the

online games, you can login normally but cannot join a team with other players. To solve this problem, set your PC as a DMZ host with all ports open.

1. Assign a static IP address to your PC, for example

192.168.0.100.

2. Visit http://tplinkwifi.net, and log in with your TP-Link ID or the password you set for the router.

3. Go to Advanced > NAT Forwarding > DMZ and select Enable

DMZ.

4. Enter the IP address 192.168.0.100 in the DMZ Host IP

Address filed.

5. Click Save.

Done!

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.

12. 4. Make Xbox Online Games Run Smoothly by UPnP

The UPnP (Universal Plug and Play) protocol allows applications or host devices to automatically find the front-end NAT device and send request to it to open the corresponding ports. With UPnP enabled, the applications or host devices on the local network and the internet can freely communicate with each other thus realizing the seamless connection of the network. You may need to enable the UPnP if you want to use applications for multiplayer gaming, peer-to-peer connections, real-time communication (such as VoIP or telephone conference) or remote assistance, etc.

Chapter 12

Tips:

• UPnP is enabled by default in this router.

• Only the application supporting UPnP protocol can use this feature.

• UPnP feature needs the support of operating system (e.g. Windows Vista/ Windows 7/ Windows 8, etc. Some of

operating system need to install the UPnP components).

NAT Forwarding

For example, when you connect your Xbox to the router which has connected to

the internet to play online games, UPnP will send request to the router to open the corresponding ports allowing the following data penetrating the NAT to transmit. Therefore, you can play Xbox online games without a hitch.

LAN WAN

Internet

XBOX Router

If necessary, you can follow the steps to change the status of UPnP.

1. Visit http://tplinkwifi.net, and log in with your TP-Link ID or the password you set for

the router.

2. Go to Advanced > NAT Forwarding > UPnP and toggle on or off according to your

needs.
