•

AP Isolation:

Select this checkbox to enable the AP Isolation feature that allows you to

confine and restrict all wireless devices on your network from interacting with each

other, but still able to access the Internet. AP isolation is disabled by default.

•

WDS:

Select this checkbox to enable the WDS (Wireless Distribution System) Bridging

feature to allow the router to bridge with another access point (AP) in a wireless local

area network (WLAN). Refer to

Appendix B: Troubleshooting

for detailed instructions.

Set Up a Dynamic DNS Service Account

Most ISPs (Internet service providers) assign a dynamic IP address to the router and

you can use this IP address to access your router remotely. However, the IP address can

change any time and you don’t know when it changes. In this case, you might need

the DDNS (Dynamic Domain Name Server) feature on the router to allow you and your

friends to access your router and local servers (FTP, HTTP, etc.) using domain name, in

no need of checking and remembering the IP address.

Note:

DDNS does not work if the ISP assigns a private WAN IP address (such as 192.168.1.x) to the router.

To set up DDNS, please follow the instructions below:

1°

Visit

http://tplinkmodem.net

, and log in with the password you set for the router.

(Dyndns or NO-IP). If you don’t have a DDNS

account, select a service provider and click

Tips:

If you want to use a new DDNS account, please log out first, then log in with the new account.

Create Static Routes

A static route is a pre-determined path that network information must travel to reach

a specific host or network. Data from one point to another will always follow the same

path regardless of other considerations. Normal Internet usage does not require this

setting to be configured.

Visit multiple networks and multiple servers at the same time.

For example

, in a small office, my PC can surf the Internet, but I

also want to visit my company’s server. Now I have a switch and

another router. I connect the devices as shown in the following

figure so that the physical connection between my PC and my

company’s server is achieved. To surf the Internet and visit my

company’s network at the same time, I need to configure the

static routing.

Company’s server

172.30.30.1

Make sure the routers use different LAN IP addresses on the

same subnet. Disable Router 2’s DHCP function.

Click

Add

to add a new static routing entry. Finish the settings

according to the following explanations:

•

Destination IP:

The destination IP address that you want to

assign to a static route. This IP address cannot be on the same

subnet with the WAN IP or LAN IP of the router. In the example,

the IP address of the company network is the destination IP

address, so here enters 172.30.30.1.

•

Subnet Mask:

Determines the destination network with the

destination IP address. If the destination is a single IP address,

enter 255.255.255.255; otherwise, enter the subnet mask of

the corresponding network IP. In the example, the destination

network is a single IP, so here enters 255.255.255.255.

•

Gateway:

The IP address of the gateway device to which the

data packets will be sent. This IP address must be on the same

subnet with the router’s IP which sends out the data. In the

example, the data packets will be sent to the LAN port of

60

Chapter 11

Specify Your Network Settings

Router 2 and then to the Server, so the gateway should be

192.168.1.2

•

Interface:

Determined by the port (LTE/LAN) that sends out the

data packets. In the example, the data is sent to the gateway

through the LTE port, so LTE should be selected.

address to visit the company network.

Set up a

VPN Connection

VPN (Virtual Private Network) is a private network established across the public network,

generally via the Internet. However, the private network is a logical network without

any physical network lines, so it is called Virtual Private Network.

With the wide application of the Internet, more and more data are needed to be shared

through the Internet. Connecting the local network to the Internet directly, though can

allow the data exchange, will cause the private data to be exposed to all the users on

the Internet.

The VPN (Virtual Private Network) technology is developed and used to establish

the private network through the public network, which can provides a secure

communication to a remote computer or remote network, and guarantee a secured

data exchange. IPSec is one of the major implementations of VPNs.

Establish an IPSec VPN tunnel to connect two LANs via Internet so

that the hosts in different remote LANs are able to communicate

with each other as if they are in the same LAN.

For example

, I am the network administrator of a regional office,

I need to let my office staff to visit the headquarters’ servers and

resources, and vice versa. I know that the router in my office and

the device in headquarters both support IPSec VPN feature, so I

decide to set up a VPN connection with the headquarter office.

The following diagram is a typical VPN topology. Here Site A

refers to regional office’s network (local network). And Site B

refers to the headquarters’ network (remote network) which I

want to connect to.

Done!
