Skunks/ettes, Good evening. Has any of you implemented failover on linux. The setup is as follows, I have a linux box running a redhat distro..or any other distro, 3 network cards. One network card is the LAN IP say 192.168.1.1, the other 2 connect to the ISP..failover is between the 2 ISP links. How do you track such that you use ISP A and failover to ISP B when A has a problem. Please note I don't want to load balance, Only one link at a time should be used. Looking forward to your responses. Kind regards, George.
