Uptime is not of that critical importance, I'm very well aware of all the big-$ stuff which could be implemented when it is. For this customer, we're talking small business: there was a business ADSL-line (isp1) which is perfectly fine. Maybe not the hardware you consider business, but it is supplied with a decent router for its purpose, has virtually no downtime and good SLA for $. Now, for some extra upload-bandwidth, we added a consumer cable-connection to isp2. To use this as transparent and convenient as possible, it would be nice if this connection IS used when it is fine and IS NOT used when it is down. My simple question remains: which tools can be used to monitor the extra connection and act uppon changes? 1) switch Shorewall-configuration to "isp1-only" set of files when isp2 goes down 2) restart Shorewall when the dynamic IP of isp2 has changed in order to implement correct routing rules Are there any people out there using multiple ISP's and doing some kind of failover something like this situation?
