Here i like to share my experience with the great!! great!!! BSNL ADSL2+ Router and how i banged my head with that router😛
While i am staying in coimbatore i am AIRTEL Customer . In their ADSL2+ Router under the NAT i have NAT Virtual Servers Link , Port Triggering and DMZ. I use Nat Virtual servers to do port forwarding to my system so that i can play games host some servers like Apache , ftp in different systems on my LAN.
After myself shifting to chennai i bought BSNL Broadband Connection because of only reason that in my locality Airtel is not Available . To my bad surprise as usual i opened the router configuration page by typing http://192.168.1.1 . Under the NAT there is only DMZ no other links😦 . I want the dam Nat Virtual Server Setup . So i started to pondering how to do that.
Some People recommended to put my Systems LAN IP in DMZ host . Thats really really not recommended because your are putting your system in big security risk unless you have really good Operating system level firewall .
Note : I am talking about DMZ host not DMZ Zone for further reading http://en.wikipedia.org/wiki/DMZ_%28computing%29
And also you cannot able to port forward different services to different servers in your LAN.
To know more about port forwarding www.portforward.com
Here is a how to do a portforward in BSNL WA3002G4 by using a Hidden Link
I dont know why that link is hidden from the users . And also i am wondering who hidden that from the end user whether the manufacturer UTStarCom or BSNL .
How i found that they have hidden the link . I sshed the router and It’s there to my surprise . have a look at the below picture🙂
here is the how to to add a virtual server by using ssh
download Putty login with your username and password Go to NAT–> 1 Virtual servers –> 1 Add
Note : Internal Server IP Address Should be your LAN ip address
But i Request you to go for http configuration by using the link http://192.168.1.1/scvrtsrv.cmd?action=view for better understanding.
