Port forwarding in Airtel Wireless Lan:

When you want computers outside your LAN to access your computer. Some examples can be when u set up a ftp server on my machine for other people to access, or you are running a bittorrent client or DC++.

Steps:
• Step 1 : Put an internal static IP on your machine.

o Open Network Connections.
o Right click on Local Area Connection and select Properties.
o Now select TCP-IP and click on Properties
o Put values as shown. The DNS Server values I have put are that opendns You can also put 192.168.1.1 to use the airtel dns






• Configuring the Airtel Modem.

o Open http://192.168.1.1/main.html in IE
o Go to Advanced Setup -> NAT -> Virtual Servers
o Server IP will be same as the IP Address as mentioned above, which is 192.168.1.10 i this case







o If you want to play Network Game, you can just select this from the dropdown. Click on Save/Apply and you are done.
o In case the service isn't pre-configured, such as Bittorrent. Click on Custom Service. Put the name bittorrent
o You would need to put which port to forward. bittorren typically runs on 19556, so put 19556 in all the four text fields i.e. External Port Start, External Port End, Internal Port Start and Internal Port End.
o Choose the protocol. In case of bittorrent, and in most other cases, it would be TCP. Click on Save/Apply.
o That’s it, enjoy playing games, using torrent and DC++
Please note that these steps are applicable only if you are not using any other routers (wireless or otherwise) with your modem.
