Is there any difference in bytes upload/download in case of Bridged or PPPoE??
Is PPPoE consumes more data even when my lappy is switched off?

Those are common myths which are associated with PPPoE mode. I am also on a data-cap plan. Yet i havent noticed any extra data transfer with PPPoE mode.

There is no difference. It's the same in both pppoe & bridge mode.

Yes, a little amount to keep the connection alive.

Bridge mode is a little convenient for people who uses Night Unlimited feature, that's all. So no need to use it because you have limited data plan.

I have used pppoe mode in Home 250 plan.

In PPPoE mode, there is always some data exchange going on while the modem is ON. This data exchange goes on to keep the connection alive. Usually this data exchange is around 1~2 kB/s.

To avoid this, check the option that sets idle timer ON. If the connection is idle for more than the specified time, the connection will be terminated.

Thanks all for reply.
So technically speaking, there is no extra bytes eaten in PPPoE.
And if modem is powered OFF, then there is no bytes wastage.

I switched to PPPoE last week, because I will also configure my Wi-Fi.

I also use PPPoe mode on laptop, because I cant access wifi on bridge mode, I found PPPoE mode very convenient, if any one accessing net from desktop then Bridge mode is fine. and we can secure wifi with WAP also.... so there is no worries....

u can access wifi in bridge mode

if you have multiple pcs then ppoe mode is best.. bridged mode should work as mentioned above.. just ensure that your pc is getting an ip address.

It's simple:

If you're on an unlimited plan, use PPPOE as each time you don't have to dial.

If you're on limited plan, use Bridged mode as each time you'll have to dail the connection manually. That way you can have more control over your usage unlike PPPOE mode.

From security point of view, PPPoE mode is better because public IP is allotted to the router and your computer(s) is not visible to the outside world where as in bridge mode your computer gets the IP address and it it visible to the outside world so there is a great chance of attacking your computer

Yes, but with a software firewall it can be taken care of.

Yes if you are having perfect internet security then bridge mode in complete

If you are in PPPoE mode, and because modem does not provide Virtual Server option, you are forced to use NAT/DMZ option, then it comes to the same thing. All ports, including 0~1023 are forwarded.

But the modem/router has an option in security options that can prevent common attacks thru common ports. The common methods of attack and gaining control over the router from the internet are http, telnet, ftp/tftp, snmp, etc.

Just disable the above access methods in the router from WAN. For example, in UT-300R2U (v 2.2), the security options can be found in:

Main Menu --> Management --> Access Control --> Services

Ensure the following:

Services.....LAN..........WAN
HTTP.........Enabled......Disabled
ICMP......................Enabled
SNMP.........Enabled......Disabled
TELNET.......Enabled......Disabled
TFTP.........Enabled......Disabled

So pppoe mode is best for UnLimited data plan users and bridge mode for Limited data plan users (especially Night Unlimited users).

PS. Bridge mode is not safe unless you have a good firewall software.

i always prefer the pppoe mode exactly for the reasons mentioned by archer ...

then can it be said that a user can be completely safe in PPPoE without using any software firewall...

I too have the doubt whether s/w firewall is necessary in case of PPPoE , thats why I asked the question !!

its always advisable to have a soft firewall in the PC/Laptop end as it often helps in reducing the impact of any unfortunate virus attack by not allowing it to access the net.

Bridged is better if you have only desktop to connect through wire.

PPPoE is advisable if you have to setup WiFi on your laptop and you are connecting using BSNL ADSL modem and with your personal WiFi Router.

Few minutes back, I have successfully setup my wifi router, and accessing bsnl broadband on my laptop. This wifi is done using PPPoE on Modem and then settings on my wifi router.

Everything looks fine. I have DLink 524 router.

Enable the internal firewall of the router. That should take care of the majority of the threats.

IS it possible to enable internal firewall in bridge mode ?

It depends upon the router which u are using. I can enable in mine. (DSL 2540T). But that will be no use if router firewall is enabled in bridged mode. Its is safer and more effective to use a software firewall while in bridged mode.

OK then

Is there any internal firewall in BSNL ADSL modems ? I don't think that PPOE is safer when compared to Bridge mode !

Most of the ADSL modems feature an internal firewall, which will be useful only when pppoe mode is activated. In bridged mode u need to use a separate firewall solution, but in pppoe mode, the router firewall takes care of it.

I don't think that the internal firewall(in PPOE mode) of the BSNL ADSL modem is strong enough like a software firewall ?

That means both the modes are equally unsafe without any software firewalls.
