Centos 3G failover

[Sigma721]

Hi everyone

I have a Centos server that is connected to the internet via LAN. I would like to use a 3G usb dongle as a fail over connection. I have looked around but cannot seem to figure out how to set this up.

What would be the best/most reliable way of achieving this?

Thanks in advance

Ideally I would use a separate box running something like ZeroShell.

The easiest and quickest way to do this would be to get a router that can do this for you.

I used to use Shorewall on Centos to do load balancing on two ADSL lines, I'm sure you could achieve the same with a compatible 3g modem. This is a hack to use compared to something like a dedicated router though.
