This is the sort of things that you can solve by having one or more Linux boxes with a combination of NAT and dynamic routing/loadbalancing. There are also commercial boxes that will do all what you want.

We are using two commercial routers that use IS-IS routing over two alternative providers. May be IS-IS is not very sexy, but you got those routers for free nowdays and it provide the full redundancy. In order to make this transparent for the ISPs we have a Level-2 tunnel bringing the traffic in to a site on internet. /Lars ----- Original Message ----- From: "Nick Arnett" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Tuesday, July 15, 2003 5:00 PM Subject: [BAWUG] Backup connection via neighbor? > A neighbor and I want to back up each others' home office DSL lines via > wireless, mainly for reliability, but also perhaps to provide a bit of extra > bandwidth at peaks.
