Related Configuration of IP Share Router with ezTCP

<IP Share Router>

Model: WRT 54GC Ver2.0 (LynkSYS)

Functions

 - Access Point device

 - Support DDNS

 - Support Remote management

 - Support Port Range Forwarding

There are some functions you should know how to use it when using ezTCP with IP share router.

In this description, I used a router of LynkSYS. However, if you have other routers, you don’t have to worry about it. Most of them have similar interface.

When you input the local IP address of router (192.168.1.1) in the web browser, the configuration environment will be shown like below shot.

1. Port Forwarding

Look at the below diagram.

This technique means when the packet arrived at the router, it forwards the packet to configured host with the information of port number.

Two ports should be opened at least.

The one is for the TCP connection, and the other one is for remote configuration.

The TCP port can be chosen by users but the default value of our products is TCP 1470 and the UDP port should be UDP 50005 because our configuration tool of ezTCP uses the port for remote search.

Following are the process of the configuration.
 

A. Click the [Applications & Gaming] menu.

B. Select the item of [Port Range Forwarding]

A. The comments can be set to easily identify each port.

B. Input the port numbers or ranges of numbers

C. Select protocols to the ports considering their purposes

D. Specify the IP address of ezTCP. You can set the IP address to your ezTCP with ezManager or ezConfig which are offered for configuration.

E. Check [Enabled] options.

If you do this, the router forwards the packet which is using the TCP 1470 and UDP 50005 to the device whose IP address is 192.168.1.2, when the router receive packet from Internet.

2. DDNS

When your device are in environment of assigning dynamic IP address, if you use it as a TCP server, DDNS functions should be needed.

A. Click [Setup] menu.

B. Move to [DDNS] tab.

C. Select [DynDNS.org] to use the function.

You can use other DDNS server. I use the server because I am familiar with that service.

If you use the service of DynDNS, you should register your account on the web site before doing that. (www.dyndns.com)

And they offer 5 free hosts for free and if you pay, more services are provided.

Anyway, register a hostname on the website.

These processes are needed to use DDNS.

D. Input your account's username and password.

E. Input the host name you registered.

F. Press the [Connect] button to update the IP address

G. If the update is successful, the message will be shown.

3. Remote Management

You are setting the IP share router in local network using the IP address of 192.168.1.1.

However, this supports remote management via Internet.

A. Click [Administration] menu

B. Select [Management] tab

C. Set password of the router.

D. Choose the [Remote Management] to [Enabled]

E. Define the [Remote Management Port] item. This number shouldn’t be the same as the TCP port for configuration. (TCP 1470)

Now, you can manage the router via Internet. Just input the host name and the port number on your web browser.

4. Access Point (AP)

ezTCP/WLAN products can be connected with AP in infrastructure mode. In case of CSW-H80 supports IEEE 802.11B and G. In this step, we will look at the simple configuration for use ezTCP/WLAN models.

A. Click [Wireless] menu.

B. Select [Basic Wireless Settings]

C. Choose the wireless standard modes. (We recommend the [Mixed] mode)

Other ezTCP/LAN products except for CSW-H80, only support IEEE 802.11B.

D. Set the SSID of your network. The same SSID has to be set on the ezTCP/WLAN products.

E. Click the [Wireless security]

If you want to use security options, this tab lets you do that.

There are four security modes in this AP.

Following is supported security options for each model.

* CSW-H80: WEP, WPA-PSK (TKIP), WPA2-PSK (AES)

* Other ezTCP/LAN products: only WEP

In addition, there is another security process. It is called Authentication.

A. Click the [Wireless] menu.

B. Select the [Advanced Wireless Settings] tab

C. Choose one of them. The same type should be set to ezTCP, too.

Nowadays, we use IPv4 using 32bit length. This can make a lot of addresses but not enough to allow all of the devices to access the Internet. Because of this, IPv6 system has been raised and will be used soon. However, in many points like interfacing with previous system, it’s going to be needed a lot of effort and time. For these reasons, the protocols which assign the dynamic IP address have appeared and it is widely used throughout the world. These protocols grant an IP address to using devices, or revoke it for effective use of IP address. Even if the type may be different, most of PC in your home are used this system. This means the IP address what I am using is not would be guaranteed tomorrow. The system is definitely needed in point of solution with lack of IP addresses, on the other hand, it will be more complicated for system using IP address like socket communication program.

ezTCP supports two protocols mentioned. This means ezTCP can be operated in environment of dynamic IP address. Except this matter, however, it’s possible to be connected to internet or impossible according to types and of IP allocate and kind of IP address. This post let you use ezTCP easily in any kind of situation.

F  In above, mark of (R) means IP share router’s IP address because the cases have to use the router. Remember that it is not present the IP address of ezTCP.
