My network topology is as follows:

PC (1 nic) ======> Switch =======> 2 routers ( and

The PC has only 1 nic (ethernet port). Both routers connected to their respective isps.

Need a quick and simple way to make Ubuntu use both the broadband connections.

Please dont point me to Bonding ( That is a different thing, bonding combines 2 nics into 1.

I need to use 2 routers at the same time (like having 2 gateways at the same time)

It can't be 192.168.11. – Radu Rădeanu May 23 '13 at 10:00
I'm not sure if the stock Ubuntu is compiled with channel bonding, but that with two nics is what you really want (or a device with channel bonding between the switch and the routers) – RobotHumans May 23 '13 at 10:03
another one: :) – Rinzwind May 23 '13 at 10:16
@Radu It can be anything, just configure the router's ip address. – Silver Moon May 23 '13 at 10:27
@SilverMoon No, it can't, look here: IPv4 addresses. – Radu Rădeanu May 23 '13 at 10:35

You need a switch, that is capable of doing the bonding. Those switches are business class devices, usually with 24 or 48 ports, even 12 port office class switches can't do that typically.

Another possible solution is a gateway-server with 3 ethernet ports.

that page talks about bonding 2 nics into 1, not 2 internet connections into 1 – Silver Moon May 23 '13 at 10:12
@Rinzwind what will I need ? I have got only 1 nic on my pc, and on the other side of the Lan switch there are 2 routers. So please explain a bit more in detail in a separate answer. – Silver Moon May 23 '13 at 10:15
Sorry I missed a few words. You can not do that with that setup. You need a dedicated server for this to work. – Rinzwind May 23 '13 at 10:18
Sorry, I misunderstood the question, changed the answer. – grimpitch May 23 '13 at 10:33
