My objective is not to make the existing BSNL line go down at the same time want to configure for the AIRTEL line and once the AIRTEL line has been configured sucessfully, i can remove the BSNL line. Can this be done, if yes pl. tell me how.

It's great if we can run PPPoE for both on a single Ethernet.

Currently i have a 2-Mbps BSNL broadband connection which is terminated to our Linux Server (Fedora) which acts as the Internet gateway to our LAN users from the DSL Modem using PPPoE.

Now, i want to replace this with a new 2-Mbps AIRTEL broadband connection. My queries:

2. If i add another NIC(for the new connection) and run the

ADSL-SETUP, will this affect the existing connection.

3. Is there a way such that, i can configure this new Airtel

connection without disturbing the existing BSNL connection and just swap the DSL modem.

Not clear: do you want to replace the existing BSNL connection or do you want to have both connections (BSNL and Airtel)?

In any case, you can run PPPoE for both (or either) on a single ethernet card. That's what I'm doing with my MTNL and Airtel connections.

I could find a directory and a file in /etc/ppp/peers/ directory

1. Directory name is : isdn (i think it is not related to our setup)

2. File : wvdial, the contents of /etc/ppp/peers/wvdial is : noauth name wvdial usepeerdns

Here what should i change with respect to AIRTEL.

If i run the command # adsl-setup, it's prompting me for a new connection:

Please enter the device if you want to configure the present DSL config (default ppp0) or enter 'n' if you want to create a new one:

can i do this? Will it deactivate the present link?

Regards, George John.

Yes it can. The simplest method would be to copy your BSNL configuration in /etc/ppp/peers/ to a new file (say, Airtel) then manually edit it and change the parameters to match the Airtel connection. There may be GUI methods of doing this too, but being a command-line type of person this was what I found most convenient.

BTW, all DSL modems supplied in India tend to have the same default IP address (192.168.1.1). If you have two on the same network you will need to change the IP address of one of them.

What is "OP"

As for GUI, you can just use 'Auto eth0' of NetworkManager. I mean considering the modems can connect to ISP, the dhcp thing from dsl/adsl modem can be easily handled by NetworkManager. Swap the modem, connect the lan cable to computer and it'll be automatically connected to internet by NetworkManager.

What you're saying works if you're routing through the modems. However I don't think that's going to work here, since the OP needs to put the modem(s) into bridge mode and run PPPoE on his Linux box to make a connection to each ISP.

Well, actually there will be a single connection between modem & server, and rest of the routing work is to done by server. But IMO, the CLI method that you told is much better for server, because NetworkManager may not even be running on it (need to logon to a desktop environment that costs resource :-). Also for a server, having public IP will be better.

Hi Raju,

Hi Raju,

How do i run PPPoE for 2 ISP's (Airtel & BSNL) on a single ethernet card.

Following is my requirement:

1. I want to add an additional Airtel DSL line to the existing BSNL DSL line.(the result should be both the DSL line should terminate on to our Linux(FC4) gateway machine

2. Either of the line should be a backup line and if one ISP goes down, the internet should be up through the available line.

Please suggest me as how to achieve it.

Regards, George John.
