Thread: Difference between PPPoE and Bridge

Hi,
I have recently started using BSNL Broadband. While Configuring DLink GLB-502T modem, I have presented following option of WAN type "PPPoE" and "Bridge". I have configured Modem for PPPoE (as it worked ). So what is the difference in both WAN types??, and which is better?

In the simplest layman's terms:

A bridge is - well just like a bridge in real life - a connection between two points separated by a crevice. When you configure your router as a bridge, the connection is established from within your dialer application from Windows (or Mac). The dialer application contacts the bridge, passes on the user-id and password (in case of PPPoE) and then requests a connection to the internet. The bridge passes on the information to the ISP (BSNL in this case) and then tries to establish a connection. Once the connection is established, you are on the internet. The thing to remember is that the bridge connection does not store details about your user-id/password, etc..

On the other hand when the router is configured as a PPPoE connection, the connection is established by the router itself. As soon as the router is switched on, it contacts the ISP and establishes a connection immediately. As long as the router has power, the internet connection is always on; which is not the case with a standalone bridge.

The router can be used as a bridge or PPPoE connector so long as you have wired connections. But when you wish to add a wireless router, then one of the routers must be configured as a bridge. In case of wireless router, it is better to have the BSNL router as a bridge.

hi all, bsnl broadband configuration with ZTE ASDL Model is working well with bridgeing the modem and setting up dial up connection suing PPPoE on windows vista. but the problem is that how can i bridge the modem and establish the PPPoE connection on Ubuntu? It worked well when modem is configured on windows and changed the os to ubuntu and with sudo pppoeconf comand. but only few sites were opening. how can i solve this problem? any one recently installed bsnl broadband on ubuntu???

sudo pppoeconf is working well for me on Ubuntu with pon and poff.
What do you mean by only a few sites are opening? As I understand, it should it either work entirely or not at all. It might be a problem with your DNS server

hi, its now working... there might be DNS problems but now when i start the laptop it connects and working fine... thanks

You will get charged this way. You would need to log off from bsnl broadband and then log in again at 2:05 to get free night time usage and then log off again before the night time timings end whatever they may be in your case.

If some one tells you otherwise please be advised that they are wrong and you would end up running into huge bills that way.

i cannot understand your answer... even if i leave my router i will disconnect my bsnl connection .. i will use batch file to reconnect at 2:10..then wat is the wrong in it...

for bridge mode,using batch file to reconnect is OK.just to be sure check that this usage is recorded in bsnl portal in correct time slot the next day.

yea reconnecting is like disconnecting and connecting..2:05 am sometimes can be risky...atleast there was a difference of 7 or 8 min between my system time and bsnl server time!!

i have checked bsnl portal ... its working correctly.. but my friends are saying the one shown in portal is not the one same to calculate the bill... can i trust portal...

in bridge mode it doesn't matter if your modem is on while you connect at 2:05AM.in pppoe mode though it is must to restart the modem at 2:05AM.my clock is matched to "AAJ TAK"tv news channel & i connect exactly at 2:06AM & in bsnl portal too my time is very near to that.maybe your friends meant that do not start downloading at 2:01AM or 2:02AM.to be on safe side connect at 2:06AM after matching your system clock with the channel i mentioned.also its always better if you disconnect before 2:00AM or keep at least a gap of 2 min between disconnecting & connecting.this is to make sure that the IP you get after connecting is different from the one before.i think this also matters.

yuou can trust the portal..all entries are there..sometimes there could be a delay in the entry.. but at the end of the month you will find everything in there

still its not clear.. wat i am doing is i will disconnect my connection at the time when i go to sleep.. i will put my computer in standby.. i will use auto power on and shut down software to power on at 2:12 , at 2:14 i will schedule to launch connection , again at 2:15 i will schedule to disconnect..
then again i will launch the connection at 2:17 automatically using this software then launch utorrent at 2:20.. i will schedule to disconnect at 7:45 and then schedule to shut down the system at 7:47.. this is the procedure i am doing for 10 days.. is it ok.. will i be charged this way..

this procedure of yours is OK assuming you are using bridge mode in which you use windows to connect to net not the pppoe mode in which you can connect by just turning on the modem.

thank you.. me hoping the same.. but we cannot trust their portal.. i have to wait and see my bill.. what else procedure i can add as an additional security.. i am over cautious because i am already billed an excess of 2255 in my last bill.. till now i am getting rightly in my portal..

according to me if the timing of download is,say,2:05AM in bsnl portal then you won't get billed for that.in your last bill did you get billed for such downloads which starts at 2:05AM according to bsnl portal.if yes then you didn't need to pay for that.just get the printout of your usage & you could show it as a proof for bill correction.

i am using bsnl for 2 months only.. i got my 1st bill for january on 14th feb only.. i have been charged an extra of 1200 in that bill.. when i enquired them all i was said was to off the modem and then on to avail free hours.. then i browsed through your posts then i understood.. the problem is on 11th what i have downloaded from 2 to 8 has been entirely taken into account.. but in their portal the start time was 21:13 and end time was 08:58..i am sure i have downloaded during night only but i have kept my modem on from around 9..other days (before feb 13) even if i keep the modem on also the connection used to disconnect every 15 mins automatically.. in that day that also didnt happen.. if it had happened i would have charged for only 60 or 70 mb only.. will i be able to claim..

Hi, Im plannin to take 750 UL with wireless modem.

Cheers

Go through the many guides in "Broadband How To" section and you will probably get answers to most of your queries.
