How to configure Beetel 110BX1 to bridge mode?

I have got a new Airtel broadband connection in Hyderabad today. The modem given is Beetel 110BX1 with a single lan port. It is set as an always on connection (PPPOE). I want to use it in bridge mode with a dialer (made, for example, with RASPPOE). Earlier, I have used the bridge mode + raspppoe dialer with MTNL Triband in Mumbai without any problems and I prefer the bridge mode to the always on PPPOE mode. I know how to make a dialer with RASPPPOE. I also know how to enable the bridge mode option under the WAN settings of the 110bx1 modem. I want to know what other values need to be changed under the WAN options. Also, please let me know what I should do in case something goes wrong. I have already backed up the modem configuration to a file. Thanks in advance.
