How to connect Tata TNDSL 2120 router to Linksys wireless router for internet


I have a Tata Indicom Broadband TNDSL 2120 router configured for Direct PPPoE mode connection to internet (without dialer). Internet works fine in this mode. But when I connect the Tata TNDSL Router to Linksys wireless router (E2000) and then the Linksys Router to the computer, I am able to use the internet. What are the configuration changes that I have to make in the Tata Router and Linksys Wireless Router to connect to the internet through Wireless. I am attaching the screenshot of the Tata router settings.

Please help me with the settings so that I can share my connection over wifi.
