I have been working on trying to get Linux to pick any of the default gateways specified and have come around to this problem of dead gateway detection. It looks as if there is no support for it in Linux kernels 2,4 or 2.6. Generally all the tutorials require you to have iproute2 installed and then do some heavy kernel patching. Had a bad experience with the second part so am not keen on patching if i don't have to. What i want is to have lets say 4 different gateways specified on my Linux system and want the system to pick one of those (does not matter which one) in case the default gateway is down. Now in windows this is easy to achieve by specifying multiple gateways but in Linux is a real pain. Also does BSD kernel support this? I will Google for it but if someone has done it in BSD, i would really appreciate some guidance on where to look or tools required for the job.
