Submission + - Linux and multiple internet uplinks: a new tool
Alessandro Zarrilli writes: Linux is able do multipath routing since a long time: it means being able to have routes with multiple gateways and to use them in a (weighted) round-robin fashion. But Linux misses a tool to actively monitor the state of internet uplinks and change the routing accordingly. Without it, on a LAN perspective, it's like having a RAID0 on network: just one uplink goes down and all of your LAN-to-WAN traffic goes down too. Documentation and examples on the subject are lacking, existing solutions are few and deeply integrated in firewall/routing specific distributions. To address these issues, a new stand alone tool was just released: Fault Tolerant Router. It also includes a complete (iptables + ip policy routing) configuration generator.
