Currently I am getting three separate public IPs through three simultaneous PPPoE sessions connected through three bridged ports of the ONT. All sessions have individual maximum bandwidth of 40mbps (my plan speed). I think I can get one more public IP through the fourth port which I have kept aside in route mode for access to the ONT. However, I have not tried that for two reasons - 1) I don't need four IPs for my setup, 2) Don't want to draw unnecessary attention of Airtel's backend. Just out of curiosity, does anyone know how many simultaneous PPPoE sessions are allowed by Airtel per user?
