The answer is nothing to do with Shorewall, or even Linux ... it's a very fundamental IP question. Without explicit support from your ISP (note the singular) then the answer is NO. There simply is no way to combine multiple links with different IP addresses in this manner. Also, being pedantic, I believe you are looking for link aggregation (or PPP multilink support depending on the access technology). Bonding is some thing that can be done only at the local network layer - as in combining multiple links to get higher bandwidth between a system and a switch with such a capability. There are service providers that will provide an aggregation facility like you are looking for. With these service providers, you still need your regular internet connections, but the aggregation provider supplies a router for your premises that will create 2 or more tunnels back to them over your available links. All your traffic is then routed over these tunnels back to the aggregation provider who then routes it out over the internet - and your visible external IP is that provided by the aggregation provider. Alternatively, there are a very small number of ISPs that support multilink. In this case all your links must come from the same provider, and usually have to terminate on the same access controller. -- Simon Hobson Visit http://www.magpiesnestpublishing.co.uk/ for books by acclaimed author Gladys Hobson.
