The best bet to do it is use iptables for internet sharing and balancing.
Start off by reading about netfilter for iptables howto.
You also need to know how to balance the traffic between multiple ISP connections.
Here are some links that you can go through:

If you are using Ubuntu server, Zentyal would be worth a look. It is based on Ubuntu server, and provides support for multiple WAN inputs, including load balancing and failover.

Have a look here:

http://trac.ebox-platform.com/

As well as multiple WAN use, it provides many other network functions.

Yup. That is also one that may help. I did work with it when it was called ebox for some time. And it does look good.

Zentyal should be installed as an OS. Its got Ubuntu under the hood and only those needed packages for it to work as a router/firewall/server. You do not need Ubuntu installed. Zentyal is a distribution in itself.

While that is true, it is quite possible to install Zentyal on top of an existing Ubuntu server install. There are instructions on the web site as to how to do it. You will end up with some extras that are not needed, but it is still a viable way of getting Zentyal running.

Starting from scratch, I would certainly use the Zentyal iso, but if Ubuntu server is already installed, I would add the required packages rather than reinstall from scratch.

Paul.

While the prefered method of installing Zentyal is using the full install CD, they do also provide instructions for installing to an exisitng Ubuntu server. Have a look here:
