hi bsnluser,
finally. thanks for replying. i knew that someone would be coming up with a better explanation (seshu also did a good job, but i'm being lazy didn't trust in him. sorry seshu).
These are my doubts. (i'm using
windows xp)
i want to know what are the advantages of using the modem in "bridged mode".
Does it eliminate the need for port forwarding? >

Well, in bridge mode, you computer which is connected to the modem, practicallly gets the public IP address. The modem works like a bridge and the outside IP network practically see only your computer through the bridge. So the public IP address, the IP given to your modem by BSNL upon connection, essentially becomes your computer's IP address. Hence, you don't need any port forwarding at all in this case.
Also, if you type "ipconfig" in DOS command terminal, you will see that your public IP is listed as ppp connection.
So the advantage is you don't need any port forwarding in this case and you can connect or disconnect from your BNSL connection icon.
The disadvantages are:
1. I guess your modem's firewall needs to be off. I am not sure about this. But try with your modem's firewall off and then with it on and see if you see any difference.
2. If your modem's firewall is off, then you need to have your own firewall on your computer, e.g. Zone Alarm. However, having such a firewall is strongly recommended in any case.
3. I guess in this mode you can only connect one computer with the modem. If I am wrong, others can correct me.

or i still have to forward ports for individual applications (or playing online games).
the smartAx 882 doesnot support forwarding more than 20 ports ( that's the maximum entry that i can make in the virtual server page in
router config)

Does it allow you to forward a range of ports? You could forward, say, 60000~61999 to your computer. But this would entail you to configure your games to listen to those range of ports only.
