How to Configure Google OpenDNS on Innacomm W3400V ?

DNS LogoIn the computer network term, Domain Name System (DNS) is used to resolve the host name into an IP address. E.g. you open your browser and you want to browse google.com. Once you typed in google.com into you browser, the DNS will start its job. The DNS will send a DNS request to the DNS server, it requests the IP address of the google.com to the DNS server. It was merely like your computer asking the DNS server “Hi DNS server, I need to go to google.com, could you tell me what is the IP address of google.com ?”. Then, the DNS server will reply, “Hi there, the IP address of google.com is 179.56.72.89.” Thus, after your computer knew what is the IP address of google.com, it know where to go.

Normally, the DNS server addresses is automatically provided by the ISP. Thus, the ISP could control some websites that they want to block. They could control which website that you can go into and which website that is restricted. Some of the common blocked websites are porn sites, torrent site, and warez sites. Even though, this feature offers good things. But, sometimes you do not want to be restricted.

One of the trick to be unrestricted is by simply use another DNS server. There are a lot of parties that offering the DNS services, such as OpenDNS and Google. Some of those providers will charge you for the services. While, if you want to use a reliable and free DNS service, Google OpenDNS really will do. If you would like to know further about Google OpenDNS, you should check their official site here.

Advantages of using Google OpenDNS are:-

  1. Totally FREE.
  2. Speed up your browsing experience.
  3. Improve security by preventing several attacks such as Denial-of-Service (DOS) attacks and DNS cache poisoning.
  4. Gain access to the websites that is blocked by your ISP.

FYI, Google OpenDNS addresses are 8.8.8.8 and 8.8.4.4.

If you want to use Google OpenDNS you could either set it up on your computer’s network configuration or on your router directly. If you just set it up on your computer, that means only your computer alone that will gain the advantages of using the Google OpenDNS. While, if you set it up on your router’s configuration, every single computer that is connected to the router will also gain the advantage of using Google OpenDNS. Thus, if you have hundreds of computer that is connected to the router, all computer will automatically use the Google OpenDNS as their DNS server, but it only applicable if the DHCP is enabled.

In this post, I will specifically talk about how to configure the Google OpenDNS on the Innacomm W3400V routers.

Step 1

How to Configure Port Forwarding on Innacomm W3400V ?

Innacomm W3400V

Port forwarding enables users or certain applications to gain access to a computer or a server on a specific ports. For example, you have a web server which is served the web application on port 8080 and then you want other people to be able to access your web, but only from web browser, that means other people can just open their web browser, type-in the URL address i.e. http://www.myweb.com, without specifying the port details.

To configure port forwarding on Innacomm W3400V:-

1. Ensure that you were connected to the router.

2. Open a web browser and go to http://192.168.1.1.

7. On the Server IP Address field, you need to specify the targeted computer’s or server’s IP address e.g. 192.168.1.250. So, you should configure you computer or server with a static IP address instead of using DHCP IP address.

8. On the External Port Start field, you have to specify the port number that you want to be accessible from outside network e.g. port 80.

9. If you want to have multiple accessible ports from outside network, you have to specify the end range of the port on the External Port End field. E.g. you want to have accessible port from 80 – 90, then you need to type-in 90 on the external port end field. On the other hand, if you just want to have one specific accessible port, you just need to type-in the same number as the number on the External Port Start field e.g. 80.

10. Specify the protocol on the Protocol drill-down, you can choose between TCP,UCP,or both TCP / UDP.

11. Specify the destination port (the port on your computer that runs for that particular service) on the Internal Port Start e.g. 8080.

12. Similar with the  External Port Start, if you have a range of internal ports, you have to specify the last port in the range on the Internal Port End field e.g. 8090. But, if you only have one external port, this field will be disabled automatically.

13. Once you have done, click Apply / Save.

14. Your new entry will be listed on the NAT – Virtual Servers list.

How to Change Innacomm W3400V User’s Password Through SSH?

FYI, Innacomm W3400V is a free ADSL Modem + WiFi Router from Streamyx.

This modem + router have been branded by TM, so it have its own log in page. The funniest thing is the log in page is do some JavaScript to check whether the username and password specified contain any special characters, such as !@#$%^&*. So, that means you cannot use any special character on your password. But, if you try open the configuration page and change your password using special character, it will accept it.

The problem starts here. I have changed the admin user password on my router using special characters. So, every time I tried to log in, it always says the password is wrong, authentication failed, and so on.

So, I tried to find a workaround to change the password back, without go through the log in page.

1. Open PuTTY . PuTTY is a Windows based SSH / Telnet client and it quiet useful, if you do not have it, you can Google it and download it for FREE!.

2. SSH to your router, enter your router IP address, normally it should be 192.168.1.1.

3. Once you connected, it will prompt you for username, just type in the username that you want to change the password e.g. tmadmin

4. Then, it will prompt again for password, enter the password.

5. If you have successfully authenticated, the Main Menu will appear.

6. Type passwd <option> <new_password> e.g. passwd admin password then enter.

7. There are 3 options for passwd command, which are admin, user, and support. Normally the username for admin is tmadmin, for user is tmuser, and I don’t know the username for support.

8. After that save the configuration by type in save and enter.

9. Reboot your router, either reboot it by turn it off and turn it on again or type in reboot.

10. Open your browser and open router’s web config. Log in with new password.

VOILA! You have changed the password!
